Which of the following molecular structures contain codons?A) tRNAB) rRNAC) a proteinD) mRNA

The correct answer is: D) mRNA.

Explanation:

mRNA is the molecule that is created from a DNA template in the process of Transcription. The mRNA will serve as a guide for the synthesis of proteins when Translation occurs. The mRNA consists of a sequence of nucleotides - every three nucleotides form a codon. Each codon codes for a specific amino acid - this is how the proteins are synthesized with their proper amino acids and in the correct order.

tRNA molecules, on the other hand, have anticodons that will interact with the mRNA codons. tRNA molecules are the ones that provide the amino acids.

rRNA molecules form the two subunits of the ribosome - the structure in which translation (protein synthesis) happens.

Proteins are the final product of translation.
