DNA replication begins at a single origin and the two forks â¦ However, the proteins involved that direct cell division are similar to those of bacterial systems. Hence, the nucleus is the site for DNA replication in eukaryotes. There are multiple origins of replication on each eukaryotic chromosome; humans can have up to 100,000 origins of replication across the genome. The former strand is termed as the leading strand, the latter as the lagging strand, and the intermediate fragments are termed as the Okazaki fragments. DNA polymerase III carries out both initiation and elongation. Would you like to write for us? The replication occurs in the cytoplasm of the cell. However, eukaryotic DNA replication requires special consideration due to differences in DNA sizes, unique linear DNA end structures called telomeres, and distinctive DNA packaging â¦ The basic and smallest unit of life is a cell. On the contrary, most eukaryotes utilize type I topoisomerases, that cut a single strand of DNA, during the movement of the replication fork. Original and eukaryotic DNA â¦ In addition, eukaryotes contain DNA polymerase Î³, which is involved in mitochondrial DNA replication. Both bacterial and eukaryotic DNA replication result In one DNA double helx that was the template and one completely new DNA double helx. © 2003-2020 Chegg Inc. All rights reserved. However, in certain plasmids present in bacterial cells, unidirectional DNA replication has been observed. Prokaryotic and eukaryotic DNA replication are two processes that are involved in the duplication of genomes prior to cell division. Copyright Â© Biology Wise & Buzzle.com, Inc.
