The alteration of a cytosine base in which an -NH2 group is removed is termed a(n) ______________. Question 19 options:   tautomeric shift   transversion   deamination   depurination   dimerization   translocation

QUESTION 6: Based on your knowledge of DNA replication, indicate the polarity of each primer.

Question 18 Release factors involved in translation supply a source of energy for termination of translation. bind to the stop codon in the A site of the ribosome, in place of a tRNA. release the ribosome from the ER to allow polypeptides into the cytosol. release the amino acid from its tRNA to allow the amino acid to form a peptide bond.

QUESTION 21 Choose each of the characteristic(s) of all RNA polymerases from the list below. A. elongation adds new ribonucleotides to the 3-OH B. requires a primer to initiate synthesis C. have 3' to 5' exonuclease activity D. adds nucleotides based on sequence complementarity to a template E. have 5' to 3' polymerase activity O F. elongation adds new ribonucleotides to the 2'-OH G. have 3' to 5' polymerase activity

QUESTION 16 The post-translational modification called collagen (one word = noun) is essential in the stabilization of

QUESTION 15 The researchers Hershey and Chase conducted an experiment where they radioactively labeled the proteins of a T2 phage with 35S. In a separate treatment, they labeled the DNA of a T2 phage with 32p. They allowed the labeled T2 phage to infect E. coli and then agitated the cells so that the phage would fall off of the cells. The cells were then spun down to the bottom of the tubes. When the proteins were labeled, did the researchers see radioactivity in the pelleted cells or the supernatant (liquid on top of pellet)? When the DNA was labeled, did the researchers see radioactivity in the pelleted cells or the supernatant? What conclusion did Hershey and Chase draw from this experiment?
