Question

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

Answer 1

Answer:

D) mRNA

Explanation:

In mRNA, genetic information is written from four letters, which correspond to the nitrogenous bases. This is called ogenated codon; A, C, G and U, forming long sequences of triplets. In mRNA, each of these consecutive, non-overlapping triplets is called the codon, which undergoes transient binding to the complementary aminoacyl-tRNA within the ribosome insertion sites during the translation process to establish initiation, elongation, and completion of polypeptide formation, plus a punctuation symbol.

Answer 2

Answer:

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.
