This figure represents which nitrogenous base? Hint: pairs with C   Question 42 options:   adenine   thymine   cytosine   guanine

Draw a diagram of a Ramachandran plot. Indicate the location on the plot of an amino acid residue with phi = - 90 degrees and psi = + 120 degrees.

Which one of the following statements about nucleic acids is correct? Multiple Choice NTPs can be incorporated into either DNA or RNA molecules, but dNTPs can only be incorporated into DNA molecules A nitrogenous base, 5-carbon sugar, and two phosphate groups would most accurately be referred to as a nucleotide diphosphate. During nucleic acid synthesis, the phosphate group at the 3' carbon of the incoming monomer is covalently linked to the hydroxyl group at the 5' carbon of the existing macromolecule. RNA and DNA have all the same pyrimidine bases in them, but differ in the selection of purine bases. A nucleic acid found in a cell with the sequence GCCTTATCGCG would most likely be found paired with another molecule in double-stranded form.

Name the structure below:  A. Adenosine B. Cytidine C. Thymidylate D. Adenylate
