Answer: Option A) How many codons make up a typical mRNA molecule?
Explanation:
A messenger RNA (mRNA) molecule is a class of RNA molecules, each of which is complimentary to one strand of DNA. It carries the genetic information of genes from the chromosomes to the ribosomes where the information is translated into the amino acid sequence of a polypeptide.
Thus, the codons on a typical mRNA molecule differs from the DNA template strand by the presence of URACIL (U) instead of thymine (T).
Translation is the process that occurs when mRNA is read by the tRNA in the ribsome
