Answer:

A cap is added to the 5 end of the mRNA

Explanation:

In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.

One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.

Thus, the selected option is correct.

Which of the following could be done to help reduce global warming trends?
timama [110]

Answer: A. Plant more trees

Explanation: Planting more trees can reduce more pollution that is in the air.

B is wrong because by bottling up more water, it requires more plastic that may be littered on the ground. Raising more livestock is helps the environment through their feces, but it doesn't help global warming trends. Building more schools does not even reduce global warming trends at all. It may do more damage if machines that produces pollution are used during the process of building.

Hope this helps!!!

This lead to the discovery of the penicillin compound.

Thus, Option-A is the correct answer.
