DNA molecules are very long. They wrap around proteins and wind tightly‚ forming structures called chromosomes. A human somatic (non-sex) cell has 23 pairs of chromosomes. Twenty-two pairs are autosomes‚ which do not differ between the sexes. The autosomes are numbered from 1 to 22‚ with 1 the largest. The other two chromosomes‚ the X and the Y‚ are sex chromosomes. The Y chromosome bears genes that determine maleness. In humans‚ a female has two X chromosomes and a male has one X and one Y. Charts
