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.Know More
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
A dependent variable in biology is an element that is being tested. It relies on the independent variable, or that aspect of the experiment that the scientist has control over and changes to observe the results on the dependent variable.Full Answer >
In biology and all other forms of science and mathematics, a controlled variable is one that is completely controlled throughout an experiment. Controlled variables stay constant throughout experiments and are carefully controlled and observed.Full Answer >
There are many significant differences between prokaryotic and eukaryotic DNA replication. One such difference is the complexity of the replication process of eukaryotic cells in comparison to the relative simplicity of the replication process in prokaryotic cells. Another huge difference is the speed at which replication takes place.Full Answer >
In biology, a vector is any organism that facilitates the spread of a disease. Vectors do not inherently cause diseases but are mere vehicles of the germs that cause disease. Vectors may include small insects or larger animals that carry viruses from one host to another.Full Answer >
