Alu Patterns

Discussion
Alu is a transposable element that can be inserted into the human genome, enabling its use as genetic marker for ancestry differentiation,and thus identification. Due to new insertions, some humans do not have an alu insertions, while others may have accumulated mutations causing three types of polymorphisms, S1, S2 and L, the reference alu insertion, YB8 was useful as a standard to the comparison of nucleotide sequences changes to uncover the difference in the presence and absence of alu insertions, and the various alleles occurred by restriction enzyme digestion. In this lab, the presence of the alu alleles were investigated in the DNA of individual 1 and 2 to determine whether the alu elements can be used as genetic marker to identify race.
The null hypothesis stated that alu elements could not be used as a genetic marker to identify race. The alternative hypothesis (H1) stated that as individual 1 was an african american, they would have at least one alu allele thus, unable to have the S1/- allele, and the homozygous for the L

It is suggested that future studies should consider the amount of water used to dilute the buffer when conducting electrophoresis, as that might affect the migration ability of the DNA. The experimental design should also consider the amount of restriction enzymes, and the amount of DNA used, if more fragments of the DNA are able to be cut, then more accurate representations of these sequences can be produced during electrophoresis. In addition, ensuring correct temperatures during the denaturing, annealing and extension steps could be beneficial to the creation of accurate PCR

    The purpose of Syber-Safe DNA stain is for the stain to bind to DNA and allow the DNA to glow under UV light. The difference in function between the loading dye and Syber-Safe DNA stain was that the loading dye does not bind to the DNA but tracks the DNA during electrophoresis while the Syber-Safe DNA stain will bind to DNA and will help visualize the DNA under UV light. The purpose of a molecular ladder in gel electrophoresis is to serve as a reference to approximate the size of the unknown DNA molecules through LoggerPro software. The molecular ladder is used to determine unknown DNA fragments by using known DNA fragment size as…

    Putty was opened on lab computers on the first day of this lab. Next, the group used Putty to input potential restriction enzymes to see where they would cut the DNA, and how long each of these fragments was. The restriction enzymes observed through the program were AseI, BsrGI, ClaI, EcoRV, HindIII, HpaI, NcoI, and PvuII. The lab group then chose to use BsrGI for the experimental restriction enzyme since they believed it would make the mutant DNA linear since it would cut the plasmid once while leaving the wild-type DNA uncut and supercoiled. This would make the wild-type DNA travel faster through the agarose gel in gel electrophoresis.…

    PCR is used to magnify the 16S rRNA gene and is used in molecular biology to make thousands of copies of the magnified DNA. There are three main stages that the PCR carries out, the first is denaturing when the double-stranded DNA is separated into two strands. Second, annealing which enables the DNA primers to attach to the DNA when the temperature is lowered. Lastly, extending which is when a new strand of DNA is created by the Taq polymerase enzyme when the temperature is raised. This process is run in cycles 29 times and takes approximately 4 hours to complete.…

    The concept of race has historically been flawed at best. This type of human categorization, which draws no basis of biological evidence, has been used for centuries to successfully subjugate large groups of people, paving the way for white supremacists to gain even more emotional, and ergo economic, control over the American working class. Patrick Appel is not the first to delve into the myth of “race”, but he does offer a well-rounded, professionally composed vindication that responds to several misinterpretations of scientific research in the field of genetics. Appel presents this through his 2014 article, “Why ‘Race’ Isn’t Biological.” Biologically, races are defined as “genetically distinct populations within the same species” (Live…

    . These hypotheses do not suggest differing biology, they merely suggest that ancestral traits were chosen for to maintain survival against the selective agent. The general public misunderstands inherited ancestral traits to be biological variation amongst race groups. In Clarence Gravlee’s article, “How Race Becomes Biology: Embodiment of Social Inequality” he wrote, “The central argument is that the race concept is inadequate for describing the complex structure of human genetic variation.…

    Gel electrophoresis is a method used for separation and analysis of molecules such as DNA, RNA, and proteins, based on their sizes and polarity. DNA (deoxyribonucleic acid) is a molecule that carries most of our genetic information, and possesses a negative charge. During gel electrophoresis, DNA fragments can migrate through the gel also known as agarose when placed in a powerful electrical field. The rate at which the DNA fragments will move through the gel depends on their relative size. Horizontal gel slabs are commonly used on conducting gel electrophoresis.…

    Essay Question: What is the difference between the way race is defined in the United States and in Brazil? List the Brazilian folk taxonomy of "tipos" and how to translate "tipos" into U.S. racial categories. Race is a myth. In another word, what looks like a difference in biological variability, is in fact, merely a difference in cultural classification. Similarly, anthropologist have stressed that U.S. racial groups are American cultural structures that depict the way Americans categorize people, rather than it be “a genetically determined reality (Spradley and McCurdy 200).”…

    Social Construction of Race Social Construction Social construction is understood in sociology as a theory of knowledge which examines and evaluates the development of communally constructed understandings of the universe that function to form the background for similar assumptions relating to reality. Social construction dictates that all aspects of the world are inexistent or they do not have meaning unless they are given meaning by the society. In this sense, the society dictates the important issues and it outlines the laws and regulations that help to govern the establishment of a community and the behaviors of people. With regards to race, social construction influenced the development of a negative perception that has developed through time, despite significant efforts to promote equality.…

    Biology is associated with race in the fact that we are genetically similar to species with very few genetic variations across the globe and determined by the way we look. The characteristics can distinguish race by the skin, hair, or eye color. Race is also made up of meaningful categories of people; meaning different groups of made up of people who decided they were important. Such as Caucasians, African Americans, and Latinos. Race refers to groups of people with similar physical features from similar genetic ancestry sharing transmitted traits.…

    Introduction When observing a human population there are many phenotypical differences such as; behavior, development, and morphology. Not only are there phenotypical differences amongst a human population, but there are also genotypic differences that can be observed using DNA sequencing data. One way to observe genetic variation amongst humans would be to sequence the Mitochondrial DNA(mtDNA). Mitochondrial DNA is the most commonly used DNA to form phylogenetic trees. Human Mitochondrial DNA is about 16,500 bps in size and consists of 13 protein coding genes, 22 tRNAs (transfer RNA), and 2 rRNAs (ribosomal RNA) (Ingman, 2001).…

    Question 3 Throughout the majority of history in the United States and to this present day, “race” has been an issue. It causes hostility and disagreements amongst individuals due to their perceptions of what truly is. By definition, race assumes that a particular ethnic group obtains a biological basis (Kottak & Kozaitis, 2012). There are different opinions of what race is from a biological perspective or a social perspective. Furthermore, there are certain circumstances were using “race” is acceptable to analyze diversity and identity.…

    Whether humans could be categorized into races or subspecies is still a huge controversy within the society. The biological definition of race is: “Race: In biological taxonomy, same thing as a subspecies: when applied to humans incorporates both cultural and biological factors.” (C.Stanford et al. 2013, p. 104) The term “race” has been popularly used to differentiate people with different skin colors and other physical traits.…

    Biology of Racism After reading “Race as Biology Is Fiction, Racism as a Social Problem Is Real” and “The Surprising Science of Race and Racism,” I’ve come to the conclusion that scientist have not yet proven a way to tell race nor racism by genetics. There have been many studies trying to show that race can be told by testing your blood or measuring the size of a human’s head but there’s no way that can be proven true. According to “Race as Biology is Fiction, Racism as a Social Problem is Real,” an article written by Audrey Smedley an American anthropologist and Brian D. Smedley, a medical researcher, "When geneticists appeared who emphasized the similarities among races (humans are 99.9% alike), the small amount of real genetic differences…

    Reading one Question: 1) Why was the social classification of race invented? Race being the social classification in which we distinguish one another by our ethnic and or regional background, enables us to not only create, but uphold systematic social status throughout the world. As proven through scientific research, race is not a substantive concept, but rather an unfounded concept that has been used to separate the human race overtime. This being the case, race was invented to create social class ranks; which sanctioned the appalling treatment of non-whites throughout the past couple of centuries. Is Afrocentrism a response to racism?…
