Typically, acetylation of histone tails leads
a. tighter packaging of the chromatin and reduced transcription.
b. increased amounts of euchromatin relative to heterochromatin.
c. activation of topoisomerase.
d. removal of the protein components of the chromatin from the dna.
e. relaxed packaging of the chromatin and increased transcription

The correct answer is e. relaxed packaging of the chromatin and increased transcription.

Explanation:

Histone acetylation and deacetylation play an important role in regulating the expression of the gene. Histone protein contains positively charged amino acids which makes electrostatic interaction with negatively charged DNA that helps in tight packaging of DNA into chromatin.

For transcription to occur this chromatin should be loosely packed so in histone acetylation acetyl group is covalently attached by acetyltransferases to lysine residue in histone tail. As the acetyl group is negatively charged it neutralizes the positive charge of histone(lysine) and allows the chromatin to become relaxed and open for transcription.

Therefore acetylation of histone tail leads to relaxed packaging of the chromatin and increased transcription.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

the answer is sex-linked recessive.
