40. Which of the following is not involved in regulating the synthesis of RNA in the eukaryotic nucleus? (A) active genes in euchromatin, and inactive genes in heterochromatin (B) amplification of some genes such as rRNA genes (C) use of different RNA polymerases to transcribe different classes of RNA (D) spliceosomes that stimulate synthesis of intron-containing hnRNAS

42. Which of the following best describes the complete sequence of steps occurring during every cycle of PCR? 1. The primers hybridize to the target DNA.  2. The mixture is heated to a high temperature to denature the double-stranded target DNA. 3. Fresh DNA polymerase is added. 4. DNA polymerase extends the primers to make a copy of the target DNA.

44. Pax-6 is a gene that is involved in eye formation in many invertebrates, such as Drosophila. Pax-6 is found as well in vertebrates. A Pax-6 gene from a mouse can be expressed in a fly and the protein (PAX-6) leads to a compound fly eye. This information suggests which of the following? (A) Pax-6 genes are identical in nucleotide sequence. (B) PAX-6 proteins have identical amino acid sequences. (C) Pax-6 is highly conserved and shows shared evolutionary ancestry. (D) PAX-6 proteins are different for formation of different kinds of eyes.

45. The first cloned cat, called Carbon Copy, was a calico, but she looked significantly different from her female parent. Why? (A) The environment, as well as genetics, affects phenotypic variation. (B) Fur color genes in cats are influenced by differential acetylation patterns. (C) Cloned animals have been found to have a higher frequency of transposon activation (D) X inactivation in the embryo is random and produces different patterns.
