What is the genes and it function?

Genes are segments of DNA that contain the instructions for building proteins, which are essential for the structure and function of cells in the body. Genes determine traits such as eye color, height, and susceptibility to certain diseases. They are responsible for passing on hereditary information from one generation to the next.

The function of genes is to provide the blueprint for the production of proteins through a process called gene expression. This process involves the transcription of DNA into messenger RNA (mRNA), which is then translated into proteins by ribosomes. Proteins carry out a wide range of functions in the body, including catalyzing chemical reactions, providing structure to cells, and regulating gene expression. Overall, genes play a crucial role in determining an individual's characteristics and overall health.
