A scientist injected a drug into a mouse that inhibits the formation of mRNA in either the sperm or egg cells.

What could be the result of this alteration?

The mouse will not be able to form sperm or egg or abnormal sperms or egg will be formed.

Explanation:

For the synthesis of proteins, the DNA is transcribed and an mRNA is formed. This mRNA is translated by the ribosomes and a protein is formed. If mRNA is not formed, then the protein will not be able to form.

If the formation of mRNA is inhibited for the sperm or egg cells they will either not form the right kind of sperm or egg cells or will not produce them at all depending on the mRNA that is being inhibited from the formation.
