- a. Do any strands of nucleic acid exist in nature inwhich part of the strand is DNA and part is RNA?If so, describe when such strands of nucleic acidare synthesized. Is the RNA component at the 5′end or at the 3′ end?b. RNA primers in Okazaki fragments are usually veryshort, less than 10 nucleotides and sometimes asshort at 2 nucleotides in length. What does this facttell you about the processivity of the primaseenzyme—that is, the relative ability of the enzymeto continue polymerization as opposed to dissociatingfrom the template and from the molecule beingsynthesized? Which enzyme is likely to have a greaterprocessivity, primase or DNA polymerase III?Show below is a polypeptide comprised of 3 α-helices and 5 β-sheets joined by randomcoil. Characterizetheforces that stabilize the tertiarystructure and draw the interacting side chains ofd) Cys Cysspecify wether the structure below have a chirality center
- Compqre and contrast the two types of nucleic acids with respect to structure and functionChemistry Write the complimentary (1) DNA nucleic acid sequence and (2) RNA nucleic acid sequence that would pair with this DNA sequence: ATTAGATCAT. We know that amino acids and proteins can move in a certain direction in an electric field when they are in solutions of appropriate pH. Would you expect lipid molecules to move in an electric field? Do you expect nucleic acids and nucleotides (DNAs and segments of DNAs and RNAs) to move in an electric field? Why or why not?Need both answer ASAP. 1.Draw the structure of pppUCGAP ribonucleic acid in the ionic form that would predominate at pH 7.0. 2.Draw the structure of ppTGACpp deoxyribonucleic acid in the ionic form that would predominate at pH 7.0.
- Adenine, cytosine, guanine, and thymineare the four nitrogenous bases found inDNA. For each molecule, identify all of thenonhydrogen atoms that are required to bein the same plane.How is it that protein–protein interactions thatare too weak to cause proteins to assemble in solutioncan nevertheless allow the same proteins to assemble intocomplexes on DNA?Briefly describe the differences and similarities of RNA and DNA. – Know the difference in their structure and function. What bases do they have, what sugars, how are they used by cells?
- a nucleotide sequence has providen to you, you have only the name of source organism. - how will you find the sequence? describe the steps. - you are informed that this sequence codes for protein how would you identify the protein using only the sequence? describes your methos using an example.Describe a nucleotide and a polynucleotide, and compare and contrastthe general structure of DNA and RNA.Within a protein, certain amino acids are positively charged (e.g.,lysine and arginine), some are negatively charged (e.g., glutamateand aspartate), some are polar but uncharged, and some are nonpolar.If you knew that a DNA-binding protein was recognizingthe DNA backbone rather than a base sequence, which aminoacids in the protein would be good candidates for interacting withthe DNA?
