Question

In eukaryotes introns are removed before mRNA elves the nucleus because:
a) They do not code for protein
b) They prevent the movement of ribosomes
c) They prevent the binding of ribosomes to mRNA
d) The mRNA would be too long to pass through the nuclear pore if the introns remained in it.
e) They do not consist of the same bases as the rest of the mRNA

Answer 1

@emmigrace222 any idea?

Answer 2

Answer Is A, they don't code for proteins, that is why the are removed.

Answer 3

agreed
Genes in eukaryotes are usually not a single stretch of DNA. Instead, there are coding regions broken up by intervening non-coding regions. For example, the average human protein-coding gene consists of 9 exons (the coding regions) separated by 8 introns (the non-coding regions). Before the mRNA leaves the nucleus, the introns have to be removed so that only the coding regions remain.
