    (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.
