One of the most important function of DNA is the replication of the another DNA. We all know that the DNA is the key factor for the transfer of the hereditary characters. But it is not an easy task for the cell to replicate the DNA it is the long and complex process. Lets discuss the methods that takes for the replication of DNA. Mostly it takes by the following three ways.
1. Dispersive method is one form for the replication of DNA. During this method the DNA replicate to make daughter DNA. The daughter DNA consists of a parental strand and a newly form strand. The two of the daughter replicated DNA one consists the parental and other form the newly strand. This method of the replication of the DNA is known as the dispersive method.
2. Conservative method is another form of the replication of the DNA. In this method the 2 daughter DNA is formed. Among which the one of the daughter is completely different from the parental form. In the same way another daughter DNA is completely different from the new strand.
3. Semi conservative method is another form of the replication of the DNA. If the original strands of DNA replicates into 2 daughter DNA. Among which those strands of parental DNA is first separated out as in form of templates. Each template if goes to combine another new strand having complementary bases such method of replication is known as semi conservative method.
The mechanism of semi conservative method of replication of DNA are as follows.
1. Origin of replication
2. Activation of deoxyribonucleotides
3. Unwinding of DNA helix.
4. Formation of RNA primer
5. Elongation of strand of DNA
6. Termination
7. Proof reading and DNA repair
In this way the mode of replication takes place in the DNA. Due to the mode of replication on the DNA. We are able to produce the offsprings that look alike us. DNA helps hereditary transformation. So it only able to do this by the replication.
