During X inactivation, all but one gene get silenced on one X chromosome. Why does one gene escape the inactivation? A) That is the gene responsible for inactivating the others B) Two copies of that gene are needed in females, so both are active C) X inactivation is rarely complete, so occasionally one or two genes get activated by mistake D) That is the gene that encodes the methyltransferase needed to methylate the genome.

Which of the following is NOT an example of a spontaneous mutation? A) errors in replication of DNA polymerase B) ALL of these are examples of spontaneous mutations C) covalent alteration of DNA by chemical products of fatty acid metabolism D) incorporation of a nucleotide analog during DNA synthesis E) failure to correct an apurinic site F) nondisjunction during meiosis

There are sometimes errors in DNA or deoxyribonucleic acid that takes place during DNA replication or due to any damage by chemicals or radiations. These errors are corrected by proofreading, mismatch repair, and excision repair mechanisms.

Solution Summary: The author explains mismatch repair is the ability of some enzymes to sense the insertion of an incorrect nucleotide and to use a DNA polymerase to insert the correct one.
