DNA

nucleotide consist of three parts: a phosphate unit, a sugar unit, and a heterocyclic base. Phosphate The sugar-phosphate backbone gives the structural its shape and how it looks like, including DNA and RNA. This backbone consists of alternating sugar and phosphate…

nucleus. B. mRNA- mRNA is called the messenger DNA. This RNA can leave the nucleus and delivers information to other parts of the cell. tRNA- Transfers amino acids to proteins. Ribosomal RNA- Forms parts of ribosomal subunits C. Proteins must be synthesised constantly in order to use the codes from genes over and over again. 2. A. During transcription, the enzyme RNA polymerase binds to DNA and separates the DNA strands. It then uses one strand of DNA as a template to assemble nucleotides into…

Plasmids are extra chromosomal DNA within some bacteria that exist as circular structures. Although they are not essential for survival of the bacterium, they often do confer many environment advantages such as antibiotic resistance. One bacteria of interest is E. coli, a gram-negative organism that is part of normal human gut flora. Some strains of E. coli are pathologic to humans, however some strains are beneficial. For example, one strain produces vitamin K, an essential nutrient. In this…

children receive only are maternal. While offspring receive equal amounts of genes from DNA in the nucleus, DNA found outside of the nucleus, such as in the mitochondria, stems only from mothers. That small quantity of mitochondrial DNA the child inherits is from a lineage of maternity, going from mother to grandmother, to great grandmother. Changes, essentially deviations from structure and order, in the DNA in general can lead to a multitude of disorders.However it is aid that “variations in…

Calculations and Pedigrees 1. In DNA extraction the proteins absorb light at 260nm and 280nm, especially the aromatic acids. 2. 250µg to nm, 250 x 1000 = 250,000ng. 3. 200ng/ml = 0.2µg/ml. 150µg/ml = 150,000µg/ml 250,000pg/µl = 250µg/ml 1mg/ml = 1000µg/ml ● 150,00µg/ml - HIGHEST CONCENTRATION OF DNA ● 1000µg/ml ● 250µg/ml ● 0.2µg/ml - LOWEST CONCENTRATION OF DNA 4. Sodium dodecyl sulphate is used as a detergent, which allows the cells to release DNA by disrupting the cell and…

soap in the Extraction solution affect the mass of DNA extracted (g) from kiwi? Aim: To see how the mass of soap in the extraction solution affect the mass of DNA extracted from a kiwi. Background Research: DNA is found in the nucleus of the cell. For this experiment, the main goals is to break apart the plant matter, dissolve the membranes of the cell and extracting the DNA found in the nucleus . To extract DNA, we would need a kiwi as DNA exists in all living organisms . The first step is…

evidence for evolution, which can be beneficial heritable traits, will arise in population over a period of time. Comparisons of Molecules (especially DNA) from different organisms- A) DNA is used to define comparison and identification of organisms. The comparison of DNA base sequences is used to elucidate relationship between organisms. DNA is a complex organisms to their offspring during the reproduction…

destroy the human race as we know it, people got scared. The fear of the unknown set in and people didn’t want anything to do with it. However, what we now is that DNA is a miracle breakthrough in the science world; creating artificial organs so that people, who need them to live, can. There was a great example of cause and effect with DNA and artificial life. Ultimately I don’t feel that is the basis or the concept that Zizek is trying to unfold in his segment in Examine Life, but more…

In Vitro Fertilization and Cas9 By Cody Dyess ENC1102 Professor Rivers 11/20/17 Outline I) Introduction A) Gene therapy B) Thesis statement: Cas9 should be used for gene therapy in in vitro fertilization to stop genetic disorders from developing in children. II) Defining what Cas9 is III) The history of Cas9 IV) Defining in vitro fertilization and its history A) Discovery B) Implementation V) Merging Cas9 with in vitro fertilization VI) Results of Cas9 against disease VII) Cas9’s…

Abstract Plasmids are circular clusters of DNA that carry valuable genes that help a host survive. The process of transformation can occur and the genetic material of the cell can be altered with a plasmid. However, the cell must be competent so it has the ability to take in DNA from the environment in order for transformation to occur properly. The E.Coli was treated with CaCl2 in order for the cell to be competent. The presence or absence of ampicillin is used to test the E.Coli’s competence…
