Answer:
<em>Translation will be affected.</em>
Explanation:
Ribosomes are the sites where the process of translation errors. Translation can be described as the process by which mRNA is converted into the amino acids which make up specific proteins of the body. If a mutation in the genes that code for proteins of the ribosome occurs, then the process of translation will be affected. Faulty proteins may be formed as a result of this mutation which can be harmful for the body.
The right answer is The cells are damaged.
Take the example of skin cells.
The skin consists of two tissues:
* the outermost, the epidermis, resting on a vascularized connective tissue,
* the dermis.
In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.
On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
