Why don't cells last the entire lifetime of an organism? a) The repeating telomeric sequence of TTAGGG interferes with normal DNA replication and leads to cell death. b) The removal of the RNA primer following DNA replication leads to a shortening of the chromosome and eventual cell death. c) DNA replication is subject to errors, causing premature cell death. d) The enzyme telomerase is readily destroyed by the environment, resulting in cell death. e) Okazaki fragments disrupt protein synthesis, resulting in premature cell death.
