Question

In RNA editing spliceosomes change the base sequence of the primary transcript and therefore the protein for which it codes. a combination of spliceosomes and enzymes creates different primary RNA transcripts from the same DNA sequence. different spliceosomes in different cells create different RNA sequences from the same primary transcript. enzymes change the base sequence of the primary transcript and therefore the protein for which it codes. microRNAs in different cells create different primary RNA transcripts from the same DNA sequence.

Answer 1

enzymes change the base sequence of the primary transcript and therefore the protein for which it codes.

Step-by-step explanation:

RNA editing refers to the post-transcriptional mechanisms by which nucleotide modifications are introduced into an RNA chain. The RNA editing processes exclude modifications produced during RNA splicing and polyadenylation. For example, deamination is an RNA editing mechanism by which an amine group from cytidine is removed by specific cytidine deaminase enzymes, thereby resulting in uridine (C to U).
