Which of the following occurs as proteins form?

A. Chains of DNA codons and RNA anti codons form.

B. Specific codons pair with specific anti codons.

C. DNA strands form a backbone of sugar rings and phosphate groups.

D. Peptides bond to nucleic acid molecules.

The answer would be B.

mRNA (has codons) is transcribed off of DNA. Then mRNA is translated into polypeptide chains. Anticodons are on tRNA molecules that bind to codons on mRNA

B. Specific codons pair with specific anti codons.

Explanation:

The nucleotide sequence of mRNA serves as a template for protein synthesis. During the process of protein synthesis, the mRNA nucleotide sequence is read in the form of triplet codons. The tRNA with the complementary anticodon sequence joins the mRNA.

There is base pairing between codon of mRNA and its complementary anticodon of tRNA followed by the formation of a peptide bond between existing amino acid on the ribosome and incoming amino acid carried by tRNA.
