First, the basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant (called a substrate) to produce products.

What is alternative splicing?

cluponka [151]

Answer: B) mRNA processing events that lead to different types of exons being spliced together

Explanation:

When DNA is transcribed into mRNA, a primary RNA or pre-mRNA transcript is obtained that includes introns and exons. For this pre-mRNA to give way to an mRNA it must undergo a maturation process of the mRNA, which

is basically to eliminate all introns primary transcript and then binding exons.

So RNA splicing is a post-transcriptional process of maturing RNA from which certain sequential fragments are removed. This process is very common in eukaryotes, and can occur in any type of RNA, although it is more common in mRNA.

Removal of introns and binding of exons in the mRNA occurs before leaving the nucleus. This process is known as splicing. <u>The alternative splicing of identical RNA transcripts into different cell types can produce different molecules of mature mRNA that are translated into different polypeptides.</u>

Semenov [28]

Hey there!

I think you mean the Finches. Each Finch has a beak that is very similar to other beaks on the other islands. This shows that they are related. Their beaks change so that they can live better in their environment. They all had a common ancestor.

I hope this helps!
