Gének
Gének are the basic units of heredity in living organisms. A gene is a discrete DNA sequence that contains the information necessary to produce a functional product, usually a protein or a molecule of RNA. Genes influence inherited traits and exist in multiple variants called alleles; the combination of alleles an individual carries contributes to its phenotype.
Genes are arranged on chromosomes and, in prokaryotes, may appear in operons; in eukaryotes they have a
Regulation of gene activity is influenced by transcription factors, epigenetic marks (for example DNA methylation and
In contemporary biology, the study of genes occurs within the genome and gene networks, aided by sequencing
