  • Pros And Cons Of Human Genetic Variation

    substitution of one amino acid for another in the protein made by a gene [1], a type of nonsynonymous substitution. Figure 2.3: Missense Mutation [1] This figure 2.3 shows an example of missense mutation. One of the nucleotides (adenine) is replaced by another nucleotide (cytosine) in the DNA sequence. This results an incorrect amino acid (proline) being incorporated into the protein sequence. 2.3.2 Nonsense…

  • Amino Acids Are Building Blocks Of Three Structural Components

    Amino acids Amino acids are building block s of proteins. Each amino acid contains main three structural components. 1) Amino group 2) Carboxcilic group 3) R group Figure 1 2016 R can be hydrogen or any other functional group .in world there are around 182-200 found to be present in nature but we can find 20 aminoacids in…

  • Unit 18 Genetics: Questions And Answers

    carry’s the majority of information for development growth and many other functions. DNA is located in the nucleus of a cell. DNA has a double helix structure and is formed by a series of bases these are Adenine , Cytosine , Guanine and Thymine. These bases have a basic pattern when forming DNA. Adenine will only join to Thymine when in DNA and Cytosine will only join to Guanine when in DNA. These bases are bonded by hydrogen bonds. Each base has a start an end in each sequence of the DNA…

  • The Importance Of Information Storage

    In this modern age of information gathering and retrieval, the thought of how and to the extent we can store information has always been an issue of paramount concern. For while libraries, hard drives, and floppy disks served their purpose in bygone times, the amount of information we have today, along with the prodigious rate it is still growing, have made them , while not necessarily obsolete, insufficient for the task. This is why the most promising method of storage in the current time is…

  • Dna In Biology

    that make up DNA are very similar except for the difference in nitrogenous base that each one contains. These bases include adenine, thymine, guanine, cytosine. When nucleotides join together they form a shape that looks like a twisted ladder (also know as a double helix). The bases of a nucleotide also determines what other bases it is paired with on the double helix. Adenine and thymine usually bond and cytosine and guanine are usually bonded together. The nucleotides that make up these…

  • Advantages And Disadvantages Of Tri-O-Acetyloride

    Under oxidative conditions, certain nucleobases (for example, adenine and cytosine) can form N-oxides. Also, the C8 position of guanosine is vulnerable to hydrolytic attack under either strongly acidic or strongly alkaline conditions. The 5,6 double bond of pyrimidine nucleosides also reacts with halogens and halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below.…

  • Difference Between B And Z DNA

    A, B and Z DNA Structure These three types of DNA all possess the similar property of a double helical structure formed from a sugar-phosphate backbone and containing the 4 bases, adenine, thymine, guanine and cytosine, complementarily paired with hydrogen bonding. A and G are purines and have a double ring whereas T and C are pyrimidines and have only a single ring. Within the helix a pyrimidine is always paired with a purine such that G is always paired with C and T with A. The difference…

  • Nucleotide Essay

    MSA University, faculty of pharmacy, Bio chemistry department. Course code PB301 Nucleotides Student name: ID: Under supervision of DR: Teaching assistant Structure Nucleic acids are polymers consist of units called nucleotides. These mononucleotide units react together by intermolecular dehydration reactions that create phosphate ester bonds. Those reactions are either, catalyzed or specialized enzymes. The nucleotide units are created by smaller types of components. Each nucleotide…

  • Aerobic Respiration And Photosynthesis Essay

    reaction that generates ATP and reduced NADP (NICOTINAMIDE ADENINE DIPHOSPHATE) which are used to power a series of reactions known as the Calvin Cycle or the light-independent stage. Aerobic respiration requires oxygen and anaerobic respiration to occur in the absence of oxygen. Aerobic respiration is a series of redox reactions that can produce up to 36 molecules of ATP per molecule of glucose and the reduced coenzyme NADH (NICOTINAMIDE ADENINE D. Aerobic respiration has four stages:…

  • The Role Of DNA In 1953

    and Crick were equipped with the knowledge to know that the number of purines in a person’s DNA was the same as the number of pyrimidines; particularly, the amount of adenine was equal to the amount of thymine, and similarly with cytosine and guanine (“Discovery of DNA Structure & Function”). These nitrogenous bases include adenine and guanine as purines, and thymine and cytosine as pyrimidines. The only step remaining would be to explain how these chains work…
