Um i going to just explain random stuff or things however you wanna say it. When a cell needs to be duplicated DNA strands are tightly coiled into chromosomes.Genes are certain stretches of DNA that code for a certain protein with a specific bodily function. On a chromosome, the location of the gene is called a locus. DNA contains all the genetic materiel that decides a person's traits, such as Hair color, Eye color, and more. Tha DnA also passes on traits from the parent to the offspring, which is why children always have common traits with their parents. Genes carry the information needed to pass on these traits. In summary, DNa, genes, and chromosomes are very similar in their composition, since genes are stretches of DNA. Their functions are the same in the sense that they are all vital in passing on traits from the parent to the child, and therefore in determining the physical traits of the offspring.
