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.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
