DNA Fingerprint Analysis Essay

research, this may become a reality very soon. One such technology capable of restructuring genetic codes in human embryos is the CRISPR-Cas9 method. This works by using an enzyme found in bacteria to snip out segments of DNA and replace the section with a customized code of DNA (Burke). Using this method, there is no limit to the changes one can make to a human embryo, whether it is enhancing intelligence, speed, strength, height, beauty, etc. A “Designer baby” is the term used to describe…

Natural Selection and Sexual Selection This world is colored by diverse species. Some of them persist but others distinct. It is natural and sexual selections that result in incredible difference. Both are leading to a process of evolution while there still exist differences between two selections. “In mammalian males, sexual selection can have a great effect on behavior and morphology than other forms of natural selection because male reproductive success usually varies much more than female…

DNA Boot Camp What is DNA First, let’s define DNA. DNA is short for deoxyribonucleic acid. It is the molecule that contains the genetic code of all organisms. DNA is in each cell of an organism and instructs the cells what proteins to make. A cell's proteins determine its function. DNA is inherited by children from their parents. The DNA in a person is a combination of the DNA from each of their parents. DNA has a double helix shape, which is like a ladder twisted into a spiral. Each step of…

Genetic engineering of designer babies is wrong not only because both unwanted traits and germline transmission of DNA can occur, but, lastly it is unpredictable and can cause an imbalance in the world. Once the genetically engineered enter into the world they can have a negative impact on the “regular people”. People cannot be sure how a baby that had cells manipulated and changed will act in society. There was a case where 30 genetically modified babies were born “healthy” after a series of…

This week’s readings have to do with race and genetics in correlation with biomedicine. In Troy Duster’s Race and Reification in Science, he talked about the ability to use genomic knowledge and apply it to the pharmaceutical field. Anne Fausto-Sterling’s The Bare Bones of Race talked about, the racial difference in bone density and uses and definitions of race in medicine. Joan H. Fujimura, Troy Duster, and Ramya Rajagopalan’s collective piece, Special Issue on race, Genomics, and Biomedicine,…

This experiment is a hypothetical representation, modelling the effects of colour mutations in “prey” and vision mutations in “predators”, and their role in natural selection. This means that different materials in this experiment represent real-life organisms and environments. The sand-coloured background represents a sand environment, while the green background represents a grass environment. The individual conducting the experiment is acting as the “predator” (bird) and the tweezers used by…

The four forces of evolution include mutation, gene flow, genetic drift, and natural selection. Mutation occurs when the base pairs in DNA change which leads to different codons being read during translation. Most mutations create codons for the same amino acid that the normal codon would have made but sometimes a different amino acid is made and that leads to changes in the organism's phenotype. Gene flow happens when two different populations come together and reproduce with each other. The…

It has been proven that yeast can grow on both YPD and SD plates. In this lab we cross several yeast strains through the process called replica plating. For this identification test only one dominant allele is required. One copy of each gene is essential to produce enough of each enzyme needed in order to make a histidine. Through the study of Saccharomyces cerevisiae we prove that by transferring yeast cells onto YPD and SD plates over a period of 24-72 hours in a thirty degrees Celsius…

Science and medicine go hand in hand, especially as it works with genes and DNA. Research and study of genetics has uncovered some underlying disorders that can now be treated because of science. Stem cells have been known to have multiple benefits when it comes to medicine. This research has not only generated treatments for health…

scientific knowledge and technological field. With this increasing knowledge the boundaries have become a thin line as the drive for discovery grows. In an alternate world such as GATTACA, technology dictates the lives of its citizens. From birth to death, DNA samples are taken that inform people of your entire history. With such an intrusive system the boundaries of science are called into question. Advancements today make it possible for such technology to exist however, ethical issues arise…
