the codon is on the ​ (a)  

the anti-codon is the ​ (b)  

• mRNA

• tRNA

Explain how the sequence of nucleotides in DNA determines the sequence of amino acids in a protein.

• By matching one nucleotide with 3 corresponding amino acids

• Through the formation of peptide bonds between nucleotides

• By determining the order of codons, which specify amino acids

• By directly synthesizing amino acids from DNA segments

The "language" of mRNA is called the ​ (a)   , and it uses three-letter "words" called ​ (b)  

• genetic code

• codons

• nucleotide strategy

• anti-codons

• amino acids

Answer explanation

The 'language' of mRNA is referred to as the genetic code, and it uses three-letter 'words' called codons to encode specific amino acids during protein synthesis.
