Question 12 If you expose a cell to chemicals that specifically disrupt the function of RNA polymerase, which of the following processes will be most directly affected? transcription translation DNA replication rate of mutation Question 13 In a ribosome in the process of translating a molecule of mRNA, the maximum number of codons that can be occupied by a tRNA at any one time is 1. 2. 3. 64. Question 14 Similar to genes that code for proteins, the products of genes that code for rRNA and tRNA must also undergo translation. transcription. replication. mutation.

Silent mutations have no effect on amino acid sequences because 1. silent mutations are usually found in noncoding regions of DNA 2. the genetic code is ambiguous. 3. silent mutations are recessive, and the presence of the dominant allele will result in a functional protein. 4. silent mutations are conditional mutagens, and their phenotypes are altered only under very restrictive conditions. 5. only a single base is involved in a series of thousands of nucleotides.

A protein-encoding region of a gene has the following DNA sequence: T T T C A T C A G G A T G C A A C A Determine how each of the following mutations alters the amino acid sequence: a. Substitution of an A for the $\mathrm{T}$ in the first position b. Substitution of a G for the $C$ in the 17 th position c. Insertion of a T between the fourth and fifth DNA bases d. Insertion of a GTA between the 12 th and 13 th DNA bases e. Deletion of the first DNA nucleotide
