Concept explainers
Interpretation: The correct definition of the codon should be determined.
Concept Introduction: Protein synthesis (translation) is a process of generating new protein sequences inside the cell. This process takes place in the cytoplasm of the cell. This process is balanced by the degradation or export of cellular proteins. It is constituted of three steps, initiation, elongation, and termination.

Answer to Problem 1P
Correct answer: Option (c), three nucleotides encode an amino acid.
Explanation of Solution
Reason for correct option:
Option (c) is three nucleotides encode an amino acid. A codon is a set of three nucleotides, that codes for an amino acid. An amino acid can have more than one codon. Hence, this option is correct.
Reasons for incorrect options:
Option (a) is an alternative name for a gene. A codon is not an alternative name of the gene. It is a set of three nucleotides that encode an amino acid. Hence, this option is incorrect.
Option (b) is three amino acids that encode a
Option (d) is one of the three nucleotides that encode an amino acid. The group of all the three nucleotides encoding an amino acid is termed as the codon. Hence, this option is incorrect.
