WebChromosomes are x-shaped structures that contain DNA, i.e. the hereditary information passed on from the mother cell to the daughter cells during cell division. Chromosomes arise when the DNA in chromatin structure (which is less condensed and can be accessed for transcription) becomes more compact. WebChromosomes and DNA Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new …
