CHROMOSOMES

A chromosome is a package containing a chunk of a genome—that is, it contains some of an organism's genes. The important word here is "package": chromosomes help a cell to keep a large amount of genetic information neat, organized, and compact.

Chromosomes are made of DNA and protein. Most living things have chromosomes that are linear, like bits of fat thread, and are kept in the nucleus, a sphere-shaped sac within the cell.

How many chromosomes do organisms have?

In a few very simple forms of life, such as bacteria, the entire genome is packaged into a single chromosome. But other organisms, with genomes a thousand or even a million times larger than those of bacteria, divide their hereditary material among a number of different chromosomes. Exactly how many chromosomes we are talking about depends on the species. A mosquito has 6 chromosomes, a pea plant has 14, a sunflower 34, a human being 46, and a dog 78.

Closely related species tend to have a similar number of chromosomes. For example, chimpanzees, our closest cousins, have 48 chromosomes in each of their cells. But aside from this general rule, there is very little rhyme or reason to how many chromosomes a species has. It would be convenient if there were some type of "evolutionary ladder," with more complex organisms having more chromosomes, but nature does not work that way. Goldfish, which spend their days swimming in circles, lazily blowing bubbles, and hovering near the top of their bowl in anticipation of fish flakes, are provided with 94 chromosomes. Cats, with their keen hunting techniques and thousand ways to purringly manipulate human beings, have only 38.
