Gene – Definition and Examples

Overview

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 However many genes do not code for proteins,In humans genes vary in size from a few hundred DNA bases to more than 2 million bases

Definition 1940s: Gene as a blueprint for a protein Beadle and Tatum 1941 who studied Neurospora metabolism discovered that mutations in genes could cause defects in steps in metabolic pathways This was stated as the “one gene one en-zyme” view which later became “one gene, one polypeptide,” In this viewpoint, the gene is being implicitly considered as the information behind the

The Evolving Definition of the Term “Gene”

Definition of a gene

 · While the first two stages generated increasing clarity about the nature of the gene, the present period features complexity and confusion, Initially, the term “gene” was coined to denote an abstract “unit of inheritance,” to which no specific material attributes were assigned, As the classical and neoclassical periods unfolded, the term became more concrete, first as a dimensionless point on a chromosome, then as a …

Gene definition, the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character, See more,

What is a gene post-ENCODE? History and updated definition

Definition of a gene

Finally we propose a tentative update to the definition of a gene: A gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products Our definition side-steps the complexities of regulation and transcription by removing the former altogether from the definition and arguing that final, functional gene products rather than intermediate transcripts should be used to group together …

 · “The definition of a gene as a DNA sequence that codes for a protein, coupled with the sequencing of the human genome, has revolutionized molecular medicine,” he said, “Genome sequencing, along with computational power to compare and analyze genomes, has led to important insights into basic science and disease,”
