Simple definition of a chromosome
WebbLocus (genetics) In genetics, a locus (plural loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is ... WebbChaque chromosome étant resté dupliqué (n chromosomes à 2 chromatides), il n'y a pas de réplication de l'ADN et la division se déroule immédiatement. Cette division consiste en une simple mitose classique : pour chaque cellule, on passe de n chromosomes doubles à deux cellules à n chromosomes simples.
