WebChromosome. Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins. They are responsible for the hereditary traits and passed from parents to offspring ... WebThe DNA at the very end of the chromosome cannot be fully copied in each round of replication, resulting in a slow, gradual shortening of the chromosome. Why is this the case? When DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand.
WebChromosomes A chromosome is one long chain of the genetic material DNA and can have hundreds to thousands of genes located along its length. To make proteins, genes spell out instructions using an alphabet of only four letters—A, C, T, and G—called bases.
