DNA is transcribed into mRNA and arranged into triplets known as what?

• A. Introns
• B. Exons
• C. Codons
• D. Genes

Answer: (C)

Genetic information is read in three-nucleotide units that specify amino acids during translation. After transcription, the messenger RNA carries these three-letter sequences, called codons. Each codon corresponds to a particular amino acid (or a stop signal), guiding the assembly of the protein. Introns are noncoding parts that get removed from the transcript, exons are the coding segments that remain in mature mRNA, and a gene is the whole hereditary unit. The triplets that directly code for amino acids in the mRNA are codons, so this term best fits the description.
