a gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. although the gene was s
Likurg_2 [28]

The most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.

<h3>What do you mean by Gene?</h3>

A gene may be defined as a stretch of DNA that contains genetic information that assists in the production of functional protein.

The type of protein may change when there will be a change in the codons. A eukaryotic gene contains introns that are removed during splicing and the codon that codes for specific amino acid may form.

But in prokaryotic genes, no introns are there, and no splicing mechanism will occur, which leads to the formation of different codons, and finally, an alteration in protein may clearly be observed.

Therefore, the most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.

Which of the following is NOT an example of a selection pressure?
Lena [83]

Answer:

B. Surgery

Explanation:

I am not entirely sure but based on the definition of selection pressure (which talks about how external agents affect the survival of an organism) surgery is does not meet the definition.

A tiger hunting a prey affects the survival of prey. Beginning of ice age is an environmental agent that can affect survival of organism that cant tolerate cold. Antibiotics are drugs that can kill bacteria thus lower their survival. Surgery can actually increase survival if some form of disease is being treated.
