What is a gene? - MedlinePlus
2024年5月21日 · 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 …

2024年12月7日 · gene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus.
Gene
3 天之前 · Genes are passed from parents to offspring and contain the information needed to specify physical and biological traits. Most genes code for specific proteins, or segments of proteins, which have differing functions within the body. Humans have approximately 20,000 protein-coding genes.
Gene - Definition and Examples - Biology Dictionary
2020年10月27日 · 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.
Gene - Definition and Examples - Biology Online Dictionary
2023年9月8日 · A gene is the fundamental, physical, and functional unit of heredity. The genes make up the sequences of DNA (genotypes). The genotypes, together with the other factors (e.g. environmental factors), determine the phenotypic trait of an organism. These changes in the genes drive evolution and natural selection. The gene was formerly called a factor.

2022年8月18日 · Genes are the functional units of hereditary, and these are made up of DNA. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes.
What is a gene? - YourGenome
Our DNA is organised into small sections, called genes. Each gene contains the instructions for making a specific product – usually a protein. Our proteins serve many functions to keep our cells functioning, such as protecting against disease or absorbing nutrients from food.
Definition of gene - NCI Dictionary of Genetics Terms - NCI
Genes are short pieces of DNA that carry specific genetic information. The basic unit of heredity passed from parent to child. Genes are made up of sequences of DNA and are arranged, one after another, at specific locations on chromosomes in the nucleus of cells.
