The diagram above shows how an mRNA molecule is synthesized. What would be the most likely result if a bacterial infection stopped the production of the RNA polymerase?

• DNA would not be replicated

• A lysosome would digest the cell

• DNA would have to leave the nucleus

• A protein could not be manufactured

A mutation is least likely to affect a cell when the mutation —

• reverses the order of bases in a DNA strand

• allows the total number of bases in a DNA sequence to remain the same

• replaces a base with its complementary base

• produces a triplet that codes for the same amino acid as the original triplet

During protein synthesis, amino acids in the cytoplasm are transferred to the ribosome by:

• mRNA

• tRNA

• rRNA

• DNA

If the diagram represents a part of the process of protein synthesis, strand A would:

• carry a code determined by the DNA from the nucleus to the ribosome

• serve as the template for making mRNA

• pick up and transfer amino acids to the cytoplasm

• pick up and transfer nucleic acids to the nucleus
