exists and is an alternate of . Chromosomes are located in the nucleus of a cell in eukaryotes. In prokaryotes (which lack a cell nucleus) chromosomes are circular in shape usually found attached to the plasmid membrane. Smaller circular DNA known as plasmids are also found in the prokaryotic cells and are thought of as smaller versions of chromosomes.
Chromosomes are made up mostly of DNA and are the structures in each of the bodyâs cells that carry the genetic information (in the form of genes) that tells the body how to develop, grow and function. Chromosomes usually come in pairs, with one chromosome from each pair coming from the father and one from the mother.Of the 46 chromosomes, two are a pair of sex chromosomes, XX (two X chromosomes) in females and XY (one X and one Y chromosome) in males. 1p interstitial deletions A chromosome 1p deletion means that the cells of the body have some genetic material missing from one of their 46 chromosomes, in this case from chromosome 1. For healthy development, chromosomes should contain just the right amount of genetic material â not too much and not too little.
