Codes for a diffusible product
- A gene is a DNA sequence that codes for a diffusible product. This product may be protein (as is the case in the majority of genes) or may be RNA (as is the case of genes that code for tRNA and rRNA). The crucial feature is that the product diffuses away from its site of synthesis to act elsewhere.

May 14, 2024 · Gene, unit of hereditary information that occupies a fixed position on a chromosome. Genes achieve their effects by directing the synthesis of proteins. They are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid (RNA).

6 days ago · What is a gene? 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.

We define a gene as a DNA sequence that is transcribed. This definition includes genes that do not encode proteins (not all transcripts are messenger RNA). The definition normally excludes regions of the genome that control transcription but are not themselves transcribed.
What are genes? Genes are strands of DNA that contain the biological instructions for life. Each gene contains sequences that determine physical and biological traits. Medical...
Feb 8, 2019 · Genes are the blueprints for building the chemical machinery that keeps cells alive. That’s true for humans and all other forms of life. But did you know that with 20,000 genes, people have almost 11,000 fewer genes than water fleas? If the number of genes doesn’t predict complexity, what does?
Oct 19, 2023 · Genes are units of hereditary information, which organisms pass down to new generations. Genes contain coded information for the production of proteins that enable cells to function. An organism ’s entire collection of genes is called its genome. The human genome contains somewhere between 20,000 and 25,000 genes.
