Question 1 a) DNA replication is the process in which a cell passes this DNA sequence onto other cells when it divides which is known as mitosis as it must duplicate its genome so each new cell has a copy. This occurs during interphase. During DNA replication the enzyme DNA helicase are important as they separate double-stranded DNA into single strands allowing each strand to be copied. DNA polymerase are another important enzyme that starts attaching new complementary nucleotides to these templates. 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 the personShow MoreRelatedDn Dna And Dna1128 Words   |  5 PagesQuestion 1 To clone complementary DNA (cDNA), it is necessary to obtain a library including the sequence of interest. Then the clones that are of interest are isolated and tested to ensure they are the right clones. cDNA is then synthesized through reverse transcription by the reverse transcriptase enzyme which yields a complementary DNA from the RNA. The cDNA is incorporated into a vector to allow for manipulation. Screening is then done using cultures such as E.coli bacterial lawns. The cDNA isRead MoreThe Uses Of Dn Dna Fingerprinting1486 Words   |  6 PagesTran Mr. Tucker AP Biology 26 August 2015 The Uses of DNA: DNA Fingerprinting Sir Alec Jeffreys’ 1984 discovery of DNA fingerprinting in England has revolutionized the criminal justice system by enabling legal entities to determine innocence or guilt of a suspect to a much higher level of accuracy(Butler). This discovery has also provided the ability to identify victims of natural disasters or catastrophes like 911(Lippincott). Additionally, DNA testing or profiling, has helped doctors and researchersRead MoreJunk Dn Dna Rna And Transcription Of Genes1966 Words   |  8 PagesJunk DNA Hengye Chen 813198898 Background: When scientists sequenced genome at early period, they found that only a small part of genomic DNA sequence can code proteins. Major DNA sequence did not have function. Then they named those DNA sequences that could not code for proteins as â€Å"Junk DNA†. However, after researching for decades, many sequences thought were useless in that time now have identified functions, such as many regulatory elements, DNA sequences coded for noncoding RNA, origins ofRead MoreHelix High Sequencing Technology : Technology And Storage Dilemma In Medicine763 Words   |  4 Pageswhile Robert (2012) presented the use of DNA as a mean to store large amount data in the range of two hundred petabytes per gram of DNA. The purpose of this paper is to present a tentative application of Helix high sequencing technology (2017) in combination with Robert (2012) technology in resolving the data storage dilemma in healthcare, especially medical radiology. To create the context for this paper, I will f ocus on the following areas: a) history of DNA as a mean of data storage—including pitfallsRead MoreDiabetic Nephropathy Case Study1448 Words   |  6 PagesAim: Diabetic nephropathy (DN), classically defined by the presence of proteinuria is one of the major late microvascular complications of type 1 and type 2 diabetes mellitus and leading to a decline in renal function. In the present study, three important single nucleotide polymorphisms (SNPs) of the PPARG gene were analysed to understand the potential modifier effect of PPARG gene on the advancement of chronic kidney disease in DN.

Deoxyribonucleic acid or DNA carries almost all the genetic information of living things on Earth and is the molecular blue print for all known life (note: some viruses uses Ribonucleic acid RNA instead). The DNA is a linear sequence that exists in a complex structure that comprises two long stretches of nucleotides, which are twisted into a double helix.
