The antibiotic erythromycin disrupts protein synthesis by preventing ribosomal translocation (movement of the ribosome relative to the mRNA). It does not affect any other step in protein synthesis. Suppose you are doing a translation reaction in vitro and you add erythromycin just before the 3rd peptide bond is about to be made. You wait a few minutes and look at the ribosome.

Circle the correct

a. The carboxyl end of AA #3 should now be covalently bonded directly to: (tRNA #2) (tRNA #3) (tRNA #4) (AA #2) (AA #3) (AA #4) (none of these).

b. Which tRNA will you find in the A site? (tRNA #1) (tRNA #2) (tRNA #3) (tRNA #4) (tRNA #5).

c. The tRNA in the A site will carry: (an amino acid) (a polypeptide) (neither) (either one)

In general, how long does it take to accomplish a long-term goal? a.a few days to a weekb.a few weeks to a monthc.a few months to a yeard. more than a year

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
