Answer   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 â¦ attached to the plasmid membrane.
A chromosome is made of a very long strand of DNA and contains many genes (hundreds to thousands). The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus).In addition to DNA, chromosomes contain other chemical components that influence gene function.very human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene. Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.
