Question

A codon is ________.

A) a series of three nucleotides found in mRNA that codes for an amino acid
B) the sequence of amino acids within a protein
C) a monosaccharide linked to a disaccharide
D) a phosphate group attached to a base
E) a membrane-bound protein that binds hormones

Answer 1

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid, playing a vital role in the genetic code and protein synthesis.

Step-by-step explanation:

A codon is a sequence of three nucleotides on an mRNA molecule that corresponds to a specific amino acid. The genetic code is comprised of these codons, each being a trinucleotide that specifies a particular amino acid during the process of protein synthesis. In the Central Dogma of molecular biology, mRNA codons are translated into a sequence of amino acids, which then fold into proteins. An example of a codon found in DNA could be ATC/GTT/GAA, with each triplet separated by slashes for clarity.
