Gene | Definition, Structure, Expression, & Facts | Britannica
网页2024年9月8日 · 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).
Gene structure - Wikipedia
网页Gene structure is the organisation of specialised sequence elements within a gene. Genes contain most of the information necessary for living cells to survive and reproduce. [1][2] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.
Gene Structure Display Server 2.0 - Gao Lab
网页GSDS 2.0 is designed for the visualization of annotated features for genes, and the generation of high-quality figures for publication. Besides the main features (i.e., coordinates of exons/CDS), other annotated features such as conserved elements and binding sites can also be displayed.

网页A gene is a sequence of nucleotide triplets of a DNA molecule bound by a start codon (ATG) and a stop codon (TGA, TAA, or TAG) that specifies a cellular product.
Anatomy of a Gene - University of Utah
网页Anatomy of a Gene. Genes are best known as the instructions for building proteins. However, only a portion of the nucleotides in a gene actually code for the protein itself. Other parts of the gene provide additional information—including sequences that control when, where, and how much protein to make.
3.8: Eukaryotic Gene Structure - Biology LibreTexts
网页2021年7月19日 · The structure of coding and noncoding regions, the DNA sequence, and more can be deduced. This is true for bacterial and viral genes, as well as eukaryotic cellular genes. The next sections of this chapter will focus on analysis of eukaryotic genes, showing the power of examining purified copies of genes.
What is a Gene? Colinearity and Transcription Units
网页Genes are not linear sequences of DNA that directly correspond one-to-one with their protein counterparts. Moreover, scientists now know that not all transcribed RNA molecules, or transcripts,...
Gene Structure and Organization - Rowen - Wiley Online Library
网页2005年9月23日 · Evolutionarily conserved blocks of noncoding sequence identified through comparative analyses across species provide starting points for experimentation. In this overview, the definition of a gene is discussed from the perspective of structural genomics, and results from the sequence of the human genome are summarized.
