Aresearcher has identified a mutant strain of yeast whose histones are unable to be acetylated. which of
the following is the most reasonable prediction for how the phenotype of this mutant yeast will differ from
the phenotype of yeast cells with acetylated histones?
o
a. the mutant will grow more rapidly
b. the mutant will grow much more slowly.
the mutant will show decrease d levels of gene express
d. the mutant will show increased levels of gene expression

The correct answer is c the mutant will show decreased levels of gene expression.

Explanation:

Histone acetyl transferase is an enzyme that helps in the transfer of acetyl group to the epsilon -NH2 group of lysine reside of histone proteins that surrounds the DNA molecule of chromosome.

  This results to make the target DNA more assecible for transcription mediated by RNA polymerase resulting the gene expression.

 On the other hand the mutant in which histones are not acetylated,transcription rate decreases as the non acetylated DNA is less assecible to RNA polymerase.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
