ANSWER QUICKLY PLS!!Which of the following gives the correct explanation as to why the mature mRNA strand is much shorter than the DNA template strand?
a) mRNA is only copied from a single strand of the DNA.
b) mRNA contains less bases than the DNA sequence.
c) The final mRNA contains only exons, the introns are removed.
d) Because mRNA is partially degraded during transcription.

Respuesta :

C would be the correct answer here. Introns are noncoding sequences of nucleotides that are removed from the pre-mRNA during splicing; the mature mRNA contains only the sequence of exons.
