Structure of genes:
A gene is composed of a nucleotide chain, which is made up of DNA strands. Genes are composed of nucleotides.
DNA consists of A, T, G, and C nucleotides. Hydrogen bonds form with opposite-strand nucleotides, and phosphodiester bonds form with adjacent-strand nucleotides
Nucleotides are composed of nitrogenous bases (A, T, G, and C), phosphate, and pentose sugar
Genes consist of two types of elements: core elements and regulatory elements.
In fact, core sequences or elements play an important role in protein synthesis. Gene expression is maintained by regulatory elements.
Among the most important elements of DNA are exons. The regulatory elements of a gene are sequences like promoters, enhancers, and silencers.
Function of genes:
A gene's primary function is to form or manufacture proteins, but it's not the only one. Indeed, it's partially true.
Some genes do not produce protein even though microRNAs, for example, are tiny ribonucleic acids formed from some genes, but they don't produce proteins. Instead, it regulates gene expression.
A gene carries instructions that determine your features, such as eye colour, hair colour, and height. For each feature, there are several gene variations.
