    In a RNA nucleotide the organic bases can be uracil, adenine, guanine or cytosine. Where as in a DNA nucleotide there can be thymine, adenine, guanine or cytosine. In RNA the pairs are UA or CG and in DNA the pairs are TA or CG. Also in DNA the five-carbon sugar is deoxyribose and in RNA the five-carbon sugar is ribose. P1 task 2 DNA: DNA is what is inside the nucleus of mostly all cells. It carries the genetic information which is what gives a living thing specific trait such ad brown hair or

    Part A Done on the attached paper. Answers to questions 1) How were you able to derive amino acids from your DNA sequence? First of all, from the sense strand given in the question, I derived the antisense strand for it. This is done by using the complementary Nitrogenous base concept. Guanine complements Cytosine, Thymine complements Adenine and vice versa. Once this is done, we obtain the antisense strand. Now the antisense strand is transcribed into messenger RNA (mRNA). Again Cytosine becomes

    human body operates is due purely to one’s genetic disposition. This is due to the way proteins are produced. In protein production, DNA is read three base pairs at a time making up for a codon which codes for a specific amino acid. These amino acids are produced in translation, and they will be strung together by something called tRNA to make full proteins. In DNA replication, there are many factors that determine the efficiency and effectiveness of what product is achieved and how it functions

    Question 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 is

    DNA polymerases are vital in how an organism can sustain life. DNA polymerases are enzymes that synthesize DNA molecules from deoxyribonucleotides and are accountable for DNA replication. They are absolutely critical for DNA replication and will typically work in sets so that they can create two identical sets of DNA strands from one single strand of DNA. DNA polymerase will catalyze the reaction: deoxynucleoside triphosphate + DNAn diphosphate + DNAn+1. DNA polymerases are extremely important because

    testimony, documentary evidence, real evidence, exculpatory evidence, inculpatory evidence, demonstrative evidence, and DNA evidence. However, the piece of evidence I will choose to talk about is DNA evidence which is also known as DNA profiling. This piece of evidence changed the landscape of the justice system when it was first introduced 1986 by Professor Alec Jeffreys; he developed DNA fingerprinting techniques to link two rapes/murders to a perpetrator named Colin Pitchfork while exonerating an innocent

    We start with a piece of DNA to the direction of 3’ to 5’ strand of DNA is called the template strand. Initiation begins at the promoter region or the consensus sequences. The promoter region of the DNA is at the beginning of the gene. Two important finding regions occur at 10 base pairs and 35 base pairs upstream of transcription. Both sequences are important as mutations can prevent initiation. Common in Bacteria is the -10 region also known as the pribnow box. It is a series of thymine and adenine

  • What Is DNA Replicated From DNA?

    800 Words  | 4 Pages

    In cells, DNA is replicated from chromosomes with two points of regulation: a six protein complex forms at an origin and is activated by proteins that can modify others (Gambus et al, 2006; Labib, 2010; Zegerman and Diffley, 2006). This draws more proteins towards the origin for initiation to occur. Origins are specific DNA sequences where the two DNA strands are unwound for replication, creating fork-like structures (Labib, 2010). Origin unwinding occurs by the six protein complex mentioned with

  • The Definition of DNA

    DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth, division, and function. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A), guanine (G), cytosine (C), and thymine (T). these nitrogen bases are bind with
