Which of the following is not a reason why histones are removed (evicted) so that eukaryotic genes can be transcribed?

With regard to eukaryotic genes, the removal and/or displacement of histones is usually necessary for

The Avy allele of the Agouti gene involves the insertion of a transposable element upstream from the normal Agouti promoter. The transposable element carries a promoter that causes the over expression of the Agouti gene. Mice carrying this allele tend to have coat colors that are more yellow than mice that don’t have this transposable element. If pregnant female mice are fed a diet that contains chemicals that increase DNA methylation, how would you expect that this diet would affect the coat color of offspring carrying the Avy allele?

The genetic code and wobble rules for tRNA-mRNA pairing are shown above. If we assume that the tRNAs do not contain modified bases, what is the minimum number of tRNAs that are needed to recognize all of the arginine codons?

An example of an epigenetic change that is caused by environmental factors is

A gene that encodes a tRNA changes the anticodon from 3′-CAG-5′ to 3′-GAG-5′. This mutation does not alter which amino acid that is attached to the mutant tRNA. What effect would this mutation have on translation?
