Textbook Question
Chapter 15, Problem 6A

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.

Yes, but only if a mutation happensarrow_forwardIf a mutation occurred in a control element sequence associated with a particular gene, which of the following would be a likely consequence of this? A. This mutation is not likely to affect the expression of the associated gene, because RNA polymerase does not bind to control elements. B. This will likely affect the expression of the associated gene because it will loosen the coiling of chromatin at this site. C. The expression of the associated gene will be affected because this change will result in a nonsense mutation. D. This mutation is not likely to affect the expression of the associated gene, since control elements are noncoding sequences. E. The associated gene's expression would likely be affected, since this mutation would change the ability of at least one transcription factor to bind.arrow_forward
