Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
mRNA is
A
used as a template to make protein
B
part of a ribosome
C
a small molecule used by the ribosome and is not made into protein
D
all of the above
Explanation: 

Detailed explanation-1: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble-in order-the chain of amino acids that form a protein.

Detailed explanation-2: -DNA, which does not leave the nucleus of eukaryotic cells, acts as a template for the production of mRNA, which carries the instructions needed for protein synthesis from the nucleus to the ribosomes in the cytoplasm.

Detailed explanation-3: -The Art of Protein Synthesis During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.

Detailed explanation-4: -The template strand acts as a base for mRNA transcription. It is also known as sense strand (plus strand) or coding strand.
