In this article we will discuss about the theta structure of DNA, explained with the help of suitable diagrams. It is a structure formed in replication of circular DNA. Since this structure resembles the Greek letter θ it is known as the theta structure. Semiconservative mode of DNA replication in bacterial chromosome begins at the origin of replication called ori [...]
Genetic modification of rumen bacteria by using rDNA technology may improve the rate or extent of lignocellulolysis in the animal. The task of developing effective rDNA technology in rumen bacteria, particularly for improving lignocellulose digestion is complex. After the rate limiting steps have been defined, it is necessary to identify and clone suitable heterologous genes for insertion into a rumen [...]
In this article we will discuss about the mechanism for the replication of DNA. The mechanism for the synthesis of DNA proposed by Watson and Crick offered the important advantage of explaining how new DNA molecules could be exact replicates of the old. According to Watson and Crick, each single strand is a template on mold for its complement, and [...]
