Question

3 tail end of mRNA has :
1) About 400 - 500 Adenosine nucleotides
2) About 500 - 600 Adenosine nucleotides
3) About 200 - 300 Adenosine nucleotides
4) About 100 - 300 Adenosine nucleotides

Answer 1

Answer:

4) About 100-300 Adenosine nucleotides

Explanation:

The mRNA end has a polyadenylate tail. During processing, the enzyme poly-A polymerase adds a chain of adenine nucleotides to the RNA, a process, called polyadenylation. This tail is around 250 residues long.

Answer 2

The mRNA tail has:

• Optional option 4) About 100 - 300 Adenosine nucleotide s.
• As we explained the main function of the tail by inserting adenosine at the end of the mRNA transport by protecting the mRNA in the cytoplasm.
• In addition, the role of the tail process is to regulate genetic expression.
• When a gene builds protein by writing and translating, it is said as expressed.
• The gene is active and builds proteins when needed.
• From now on, it is very important that the cell machine controls the amount of protein form in a particular cell or tissue.
