Edit this paragraph DNA replication

DNA is the carrier of genetic information, the parental DNA molecule itself to be a template for the accurate reproduction into two copies, and assigned to the two daughter cells go in, the carrier of genetic information to complete its mission. The double-stranded DNA structure to maintain the stability of this type of genetic material and the accuracy of reproduction are extremely important.
(A) DNA replication and a half of the
Click and Waston made in the DNA double helix structure of DNA to replicate the model during the course of research conducted and found that the process of DNA replication in the base of the hydrogen bonds between the first fracture (through the helicase), the double helix structure of the helicase separating Chain were the template for synthesis of the new chain. As the offspring of each of the DNA chain from a parent and the other is a new synthesis, so-called reservations and a half to copy (semiconservative replication).
(B) DNA replication
1. Double helix of DNA helicase
(1) single-stranded DNA binding protein (single-stranded DNA binding protein, ssbDNA protein)
(2) DNA helicase (DNA helicase)
(3) DNA chain solution
2. Okazaki fragments and the semi-discontinuous replication
3. Copy and lead to the termination of the
(C) telomeres and telomerase
American Indians in 1941 McClintock (Mc Clintock) put on the telomere (telomere) of the hypothesis that there is the inevitable end of the chromosome of a special structure - telomere. Now the role of telomeres of chromosomes are known to have at least two: ① to protect against injury at the end of chromosomes, so that the chromosome remained stable; ② connected with the nuclear lamina, so that the chromosome can be positioning.
