See also: Ribosomes During mitosis, when the duplicated DNA is being divided equally between the daughter cells, the DNA is so compactly packaged in condensed chromosomes that it is temporarily unavailable for transcription, like books that are crated for shipping to another library.
A polytene chromosome often consists of a thousand or more identical DNA double helices lying parallel in a bundle. A typical file contained about 25, focused yeast cells.

The sex cells or gametes contain haploid cells which means that these cells have one set of chromosomes, that is, 23 chromosomes. There are only 23 chromosomes in the human egg and 23 chromosomes in the human sperm. These cells are formed after they go through a special cell division called . This is a cell which contains only one set of chromosomes. These, in humans and other mammals, are mostly the sex cells (egg and sperms) produced by a process called meiosis.
