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 WebLinear Chromosomes Many eukaryotic species have multiple linear chromosomes, in contrast to prokaryotic genomes which consist of a single circular chromosome.

WebYes, there are many unicellular eukaryotes. In fact, they have their own kingdom in the standard five kingdom classification scheme in biology called Kingdom Protista. Kingdom Protista is divided into subkingdoms of Protozoa and Algae. WebProkaryotic cells may have only one chromosome, but that one chromosome is a very long DNA molecule that must be condensed to fit inside a tiny space. In a eukaryotic cell, DNA wraps around clusters of histone proteins. However, most prokaryotic cells don’t use histones to help with DNA storage. outta nowhre4:12 https://telgren.com
