Multiple Choice

Which of the following best describes a codon in the context of nucleic acids?

A sequence of nucleotides that forms the backbone of DNA

A sequence of nucleotides that signals the end of transcription

A sequence of nucleotides that initiates DNA replication

A sequence of three nucleotides that codes for a specific amino acid

Verified step by step guidance

Understand that a codon is a fundamental concept in molecular biology, specifically in the context of nucleic acids like DNA and RNA.

Recognize that a codon consists of a sequence of three nucleotides. These nucleotides are the building blocks of nucleic acids.

Each codon corresponds to a specific amino acid or a stop signal during the process of protein synthesis, which occurs during translation.

In the genetic code, the sequence of nucleotides in a codon determines which amino acid will be added next during protein synthesis.

Therefore, the best description of a codon is 'A sequence of three nucleotides that codes for a specific amino acid.'
