How many nucleotides are needed to specify three amino acids? (1 point)

9 nucleotides

Explanation:

The Central Dogma of Molecular Biology follows a pattern of gene-mRNA-protein. The genetic material is stored as DNA, which contains the instructions needed for an organism to make useful products (proteins). The DNA molecule is a nucleic acid made up of nucleotide sequences (Adenine, Guanine, Cytosine and Thymine).

The information contained in the DNA needs to be expressed via the process of transcription and translation. The transcription involves copying the information in the DNA to an RNA molecule called messenger RNA (mRNA). The nucleotides in the mRNA are read during translation in a group of three called CODONS. A codon is a triplet nucleotide sequence in mRNA that specifies a particular amino acid (which makes up proteins).

Since a group of three (3) nucleotides (codon) specify one amino acid, it will take a group of nine (9) nucleotides or three codons to specify three amino acids.
