WebIn eukaryotes more proteins (proteins are structurally complex although might function similar as complex) are involved as the DNA is far more complex. DNA plymerase has more subunits (alpha,theta,beta)-common to both pro (DNA pol 3) and eukaryotes, zeta,eta,iota,kappa,lamda ,mu,sigma, (epsilon,gamma,delta)-again common to both.

WebMar 22, 2024 · In prokaryotes, which do not have a membrane-bound nucleus, the DNA is found as a single circular chromosome in the cytoplasm. Some prokaryotes, such as … WebDNA exists in the nucleus as a condensed, compact structure. To prepare DNA for replication, a series of proteins aid in the unwinding and separation of the double-stranded DNA molecule. These proteins are required because DNA must be single-stranded before replication can proceed.

WebSep 8, 2024 · DNA gyrase, a ubiquitous bacterial enzyme, is a type IIA topoisomerase formed by heterotetramerisation of 2 GyrA subunits and 2 GyrB subunits, to form the active complex. GyrA is usually found as a dimer in solution, whereas GyrB can exist as a monomer. DNA gyrase is able to loop DNA around the C-terminal domains (CTDs) of GyrA … WebOct 17, 2024 · Eukaryotic topoisomerase II (topo II) are structurally similar and organized similarly to that of bacterial enzymes DNA gyrase (top IIA) and topo IV [34,35,36]. As fungal topoisomerase II is considered, its function is required for the segregation of daughter molecules at the termination of DNA replication and is essential for proper growth [ 37 ].
