Explanation:

Answer:
Explanation:
Proteins are involved in almost every function of cell and inside the body and each protein is specific for its role. Some of them are
1) Protein constitute major part of structure of cell. Proteins are major constituent of cell membrane along with lipids.
2) Enzymes which are proteins in nature catalyze all the important chemical reactions inside and outside the cell e.g transporting material across the cell, synthesizing and repair of DNA
3) Hormones which are proteins play important role in the regulation of metabolic reactions inside the cell
4) Regulation of cell division is performed by DNA-associated proteins
5) Proteins plays important role in storage of iron inside the cells
6) Proteins can be stored as fats inside the body and used as energy when needed by cells for its metabolic activities.
<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
<span>The right answer is: A
A) The molecule is digested by exonucleases because it is not protected at the 5' end. (correct)
B) The molecule is digested by restriction enzymes in the eukaryotic cell's nucleus. (false it is digested by exonucleases due to the absence of the 3'cap and the 5'tail)
C) The mRNA cannot exit the nucleus to be transcribed without the 5' cap and poly-A tail. (false, to be TRANSLATED and not to be transcribed)
D) The mRNA molecule attaches to a ribosome and is translated at a much slower rate. (false, it doesn't have a role to play in translation)</span>
