Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed pa
ololo11 [35]

Answer:

relaxed packaging of the chromatin and increased transcription.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.

Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

yaroslaw [1]

Answer: Sphincter muscles

Explanation:

The circular rings of smooth muscles, that can contract to regulate the movement of the smooth muscles that can contract to regulate the movement  of food through the gastrointestinal tract are known as sphincter muscles.

These two layers are outer layer and inner layer. The outer layer is longitudinal and the inner layer is circular. They contract rhythmically to squeeze food.

1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Trava [24]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
