(I) Gene regulation in eukaryotes includes all of the following levels of control except:
a. controls that affect the rate of gene transcription.
b. Controls that govern cutting and splicing g of mRNA transcripts.
c. Controls that affect the precision of mRNA transcription.
d. Controls that regulate which mRNA transcripts will be translated into polypeptides.

II. True-False statements. Indicate your choice with either T or F. (up to 12 pts.)
____ Environmental factors, such as ionizing radiation, UV radiation and chemicals can
damage DNA.
____ A point mutation is a change in one of the bases, and may have neutral outcomes.
____ Transposons are sometimes, and frivolously, called "jumping genes".
____ James Watson and Francis Crick thought that protein is a big part of DNA.
____ Barbara McClintock suggested that transposable genetic elements are responsible
for mottling in maize kernels.
____ Gregor Mendel suggested that "blending" produced phenotypic variation.
____ An operon is made up of genes that are grouped and regulated together.
____ Steroid hormones are signaling molecules that are made up of cholesterol.
____ Tumor-suppressor genes are inactivated when they undergo mutation, thereby
allowing cancerous growth.
____ Telomeres become longer and longer, every time a cell replicates itself.
____ Homeotic genes are "master control genes" that encode translation factors, proteins
which work on rRNA.
