Question

A three-nucleotide long sequence of mRNA that, during translation, directs the addition of a particular amino acid into a protein (or the termination of the process) is?

a: Anticodon

b.Codon

c.Gene

Answer 1

A three-nucleotide long sequence of mRNA that, during translation, directs the addition of a particular amino acid into a protein (or the termination of the process) is Codon.

Option b) is correct. Because, A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.

Anticodons are found on tRNA which binds to their specific codons on mRNA and add that particular amino acid to peptide chain.

A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein.

Addition of particular amino acid or termination of translation process in caused by codons found on mRNA. Stop codons on mRNA cause translation termination.

example= AUG codon on mRNA codes for methionine amino acid, while,UAG acts as stop codon which terminates the proess of translation.
