Replication in biology is the process of duplicating or producing an exact copy of the DNA involving many enzymes that split down the mother cell and create 'daughter' copies. Replication is the primary and the most significant aspect of cell division.Continue Reading
At the end of replication, the genetic material of a mother cell duplicates, and each daughter cell receives a copy. Cellular organelles also undergo replication. Replication ensures the transfer of genetic material from mother to daughter cells.
A part of the replication process is known as the replication fork. The process involves many enzymes, which includes an 11-sub-unit collective referred to as CMG, which untangles and separates the DNA into two strands. The replication fork resembles a zipper, with CMG appearing like a zipper slider and the individual strand appearing like the two rows of teeth of an open zipper.
Each of these individual strands then becomes the template for the daughter copies. The act of integrating a new integral strand to suit the template is executed by two different polymerase enzymes, which is in harmony with each complementary sub-unit of DNA to the chain. This results in a new double-stranded DNA molecule.Learn more about Biology
Considered "the building blocks" of living organisms, proteins direct many of the most basic functions in organism from the transport of oxygen, to the building of tissues to the replication of DNA. These large molecules are found in all of the cells in the human body.Full Answer >
Binary fission and mitosis are both asexual forms of cellular reproduction that duplicate the existing DNA in a mother cell and split the cell into two exact copies called daughter cells. Prokaryotes and some eukaryotic organelles use binary fission in the nucleiod. Eukaryotes use mitosis to reproduce the nucleus.Full Answer >
Unicellular organisms reproduce asexually in a process called replication. Unlike with multicellular organisms, reproduction and cell replication for unicelluar organisms is the same process.Full Answer >
Inversion in biology is the breaking of a chromosome in two places and the subsequent reordering re-insertion of the chromosome DNA. Inversions are divided into pericentric and paracentric types based on whether the centromere was involved.Full Answer >
