Chromosomes are mostly made of
WebMost prokaryotes have a single circular chromosome, and thus a single copy of their genetic material. Eukaryotes like humans, in contrast, tend to have multiple rod-shaped chromosomes and two copies of their genetic material (on homologous chromosomes). [Do all prokaryotes have one circular chromosome?] WebEvery normal cell has 23 pairs of chromosomes (for a total of 46): 22 pairs of chromosomes are the same in males and females. These are called autosomes (AW-tuh-soamz). The 23rd pair — the sex chromosomes — …
