Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome. DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand.
The origin of replication (also called the replication origin) is a particular sequence in a genome at which replication is initiated. [1] Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full ...
Tandem repeats can occur through different mechanisms. For example, slipped strand mispairing, (also known as replication slippage), is a mutation process which occurs during DNA replication. It involves denaturation and displacement of the DNA strands, resulting in mispairing of the complementary bases.
Replication of DNA always begins at an origin of replication. In yeast, the origins contain autonomously replicating sequences (ARS), distributed throughout the chromosome about 30 kb from each other. They allow replication of DNA wherever they are placed. Each one is 100-200 bp long, and the A element is one of the most conserved stretches.
Plasmid vectors minimalistically consist of an origin of replication that allows for semi-independent replication of the plasmid in the host. Plasmids are found widely in many bacteria, for example in Escherichia coli, but may also be found in a few eukaryotes, for example in yeast such as Saccharomyces cerevisiae. [8]
A special "replication terminator" protein must be bound at the Ter site for it to pause replication. Each Ter site has polarity of action, that is, it will arrest a replication fork approaching the Ter site from one direction, but will allow unimpeded fork movement through the Ter site from the other direction.
Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication between viruses is ...
