Annotated Bibliography On Dna Replication - 1682 Words

Question 1 a) DNA replication is the process, where a cell passes this DNA sequence onto other cells when it divides. It is known as mitosis as it must duplicate its genome so each new cell has a copy. This occurs during interphase. For the duration of DNA replication the enzyme DNA helicase are significant as they distinct double-stranded DNA into single strands letting each strand to be copied. DNA polymerase is another important enzyme that starts attaching new corresponding nucleotides to these patterns. It is done according to the base pairing rules, A=T, C=G, G=C and T=A. Once the new nucleotides are attached, two new sister DNA strands are formed same as the original strand. The result is two identical strands, each of which is half new. b) mRNA is a translation of DNA into a convertible protein substituting T with U. The template strand shown is the 1st step of transcription and it is transcribed to: GTA GAT TGG GGT CTC CTC. Each of the codons codes for a particular amino acid. For example, each codon is a triplet and codes for one amino acid. In the strand shown it separates it into triplets that will reveal codon and amino acid number. For example, CAT CTA ACC CCA GAG GAG = 6 amino acids. c) Sickle cell anaemia – GTA GAT TGG GGT CAC CTC Normal haemoglobin – GTA GAT TGG GGT CTC CTC While comparing the difference between the normal and sickle cell strands, it was identified that in the sickle cell there is a coding error. As the transcription error causes theShow MoreRelatedThe Human Genome Project Essay1006 Words   |  5 Pagesconstitute the human genome (the complete genetic material of an organism). The project was heralded by the research conducted in 1953 by the scientists Watson and Crick who discovered that DNA existed as a double helical structure (enabling DNA replication), from images of Rosalind Franklin’s DNA X-ray diffraction. Despite the potential positive applications of the project’s results such as in molecular medicine, it has been scrutinized for being unethical by interfering withRead MoreElectronic Media13295 Words   |  54 Pagesprovides Drosophila (fruit fly) researchers with access to submitted genomic data, genetic maps of Drosophila, addresses of other Drosophila researchers, fly stock lists (directories of which labs supply which genetic varieties of fruit fly), and a bibliography of publications on Drosophila.
