How many chromosomes in eukaryotes
WebReplication of the human genome begins at distinct chromosomal sites called replication origins. Each eukaryotic chromosome contains multiple origins that start replication in a * Co-corresponding authors. 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?]
