WebThe chromosome number, N, in eukaryotes, refers to the number of chromosomes in a haploid cell, or gamete (sperm or egg cell). Diploid cells (all the cells in our body except our gametes) have 2N chromosomes, because a diploid organism is created by union of 2 gametes each containing 1N chromosomes. WebBecause eukaryotic chromosomes are linear and much larger than prokaryotic ones, there are multiple origins of replication in the eukaryotic genome during replication. This means that replication can occur simultaneously in hundreds to thousands of locations along each chromosome. Key Points ravenswood condo 2 bathroom
