Answer:
The answer is Uracil
Explanation:
Uracil is the only nucleotide present in RNA. remember this RNA is ACGU and DNA is ACGT. See the difference?
Building Blocks of Nucleic acids are polynucleotides- <span>long chainlike molecules composed of a series of nearly identical building blocks called nucleotides</span>
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues
Shorter mRNA will be found in the ribosomes when comparisons are made
with the mRNA from inside the nucleus.
<h3>Ribosomes</h3>
Ribosomes are organelles which acts as sites for protein synthesis. This is
where the mRNA gets converted into polypeptides which have longer
chains.
Ribosomes have a shorter mRNA in the ribosome which becomes longer in
the nucleus after synthesis of larger polypeptides. this is the reason why
there is a variation in the size of the mRNA found in the ribosome and
nucleus.
