Oct 27, 2020 · A gene is an extremely specific sequence of nucleotide monomers that has the ability to completely or partially control the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid (DNA) and, in the case of some viruses, ribonucleic acid (RNA) polymers.
Sep 8, 2023 · A gene is a sequence of nucleotides in a particular nucleic acid. Thus, it is a segment in DNA or RNA molecule that encodes for either an RNA or a protein by gene expression. The nucleotide is the structural unit of a nucleic acid. It is comprised of phosphoric acid, sugar (5-carbon), and a nitrogenous base.
Feb 8, 2019 · Genes are DNA regions that tell cells how to build proteins. But we have many more proteins than genes. And much of our DNA controls when genes turn on and off.
Jan 11, 2024 · Genes are composed of a substance called deoxyribonucleic acid, or DNA. DNA contains the biological instructions that allow for the development, growth, and reproduction of life.

Aug 22, 2024 · Genes are composed of DNA and encoded for a specific purpose. How genes are encoded will determine how you look or how your body functions. Every person has two copies of a gene, each inherited from a parent. Some genes provide instructions to produce specific types of proteins.
May 21, 2024 · A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins, which are needed for the body to function. However, many genes do not code for proteins, instead they help control other genes.
