Question

Which is a major difference between messenger rna molecules and transfer rna molecules?
a.messenger rna molecules contain ribose, and transfer rna molecules contain deoxyribose.
b.messenger rna molecules function in carrying coded information to the ribosomes, and transfer rna molecules function in carrying amino acids to the ribosomes.
c.messenger rna molecules contain thymine, and transfer rna molecules contain uracil.
d.messenger rna molecules function when they are double-stranded, and transfer rna molecules function when they are single-stranded?

Answer 1

The answer is not a because all RNA contains ribose. The answer is not c because all RNA contains uricil And the answer is not D because all RNA is single-stranded. Therefore the answer is B
