The sequence of nucleotides that determines the amino acid sequence of a protein is a:
Correct answer: D. Gene
- A. Codon
- B. Triplet code
- C. Anticodon
- D. Gene
Explanation
Genes are fundamental units of heredity, made of DNA, that carry instructions for building and operating living organisms, determining traits like eye colour by coding for specific proteins or functional RNA. Located on chromosomes within cells, humans have around 20,000 protein-coding genes, with most individuals inheriting two copies of each gene, one from each parent, influencing unique characteristics and bodily functions.
