They cannot undergo mitosis. c. They cannot exchange DNA with other cells. d. They cannot repair thymine dimers. e. They do not recombine homologous chromosomes during meiosis. 3) Which of the following sets of materials are required by both eukaryotes and prokaryotes for replication? a. double-stranded DNA, four kinds of dNTPs, primers, origins b. topoisomerases, telomerases, polymerases c. G-C rich regions, polymerases, chromosome nicks d. nucleosome loosening, four dNTPs, four rNTPs e. ligase, primers, nucleases 4) Which of the following would you expect of a eukaryote lacking telomerase? a. a high probability of somatic cells becoming cancerous b. production of Okazaki fragments c. inability to repair thymine dimers d. a reduction in chromosome length in gametes e. high sensitivity to sunlight 5) A biochemist isolates, purifies, and combines in a test tube a variety of molecules needed for DNA replication.

What has she probably left out of the mixture? a. DNA polymerase b. DNA ligase c. nucleotides d. Okazaki fragments e. primase 6) Which of the following help(s) to hold the DNA strands apart while they are being replicated? a. primase b. ligase c.
