Question

Which of the following statements BEST describes multiple 3 cleavage sites? A single pre-mRNA can be spliced in multiple ways that ultimately lead to the formation of several different proteins from the same gene sequence. Spontaneous mutations can occur within the pre-mRNA that ultimately led to the formation of several different proteins from the same gene sequence. A pre-mRNA with two or more cleavage and polyadenylation sites present ultimately leads to the formation of several different proteins from the same gene sequence. Individual nucleotides within a pre-mRNA can be added or deleted, which ultimately leads to the formation of several different proteins from the same gene sequence. Under certain conditions, only portions of the gene are transcribed, which yield variant pre-mRNA transcripts that ultimately lead to the formation of several different proteins from the same gene sequence.

Explanation / Answer

A pre-mRNA with two or more cleavage and polyadenylation sites present ultimately leads to the formation of several different proteins from the same gene sequence.

The cleavage at different sites give us different proteins from a single gene. This is seen mainly in eukaryotes.
