1) A silencer is a
(a) type of RNA polymerase enzyme
(b) protein that helps initiate transcription
(c) specific sequence of DNA
(d) complementary strand of DNA
(e) new RNA strand
2) Why don't cells last the entire lifetime of an organims?
(a) The removal of the RNA primer following DNA replication leads to a shortening of the chromosome and eventual cell death.
(b) The enzyme telmerase is readily destroyed by the environment, resulting in cell death.
(c) DNA replication is subject to errors, causing premature cell death.
(d) Okazaki fragments disrupt protein synthesis, resulting in premature cell death.
(e) The repeating telomeric sequence of TTAGGG interferes with normal DNA replication and leads to cell death.
