What are the basic components of a gene?

Exons and introns
Enzymes and promoters
Promoters and exons
Ribosomes and intron

The correct answer is: Exons and introns

A gene is a sequence of DNA that carries hereditary information and is the basic unit of inheritance. Genes are composed of exons, which are the coding regions that contain instructions for making proteins, and introns, which are noncoding regions that are removed during gene expression. Enzymes and promoters are not components of a gene, although they are involved in the process of gene expression. Ribosomes are also involved in protein synthesis, but they are not part of a gene. Therefore, the correct answer is A.
