In this article we will discuss about DNA Replication:- 1. Subject-Matter of DNA Replication 2. Modes of DNA Replication 3. Mechanism. Meaning of DNA Replication: One of the most important properties of DNA functioning as the genetic material is that it can make exact copies of itself (autocatalytic function) forming the basis for transmission of hereditary characters it controls. This [...]
The following points highlight the three main enzymes of DNA replications. The enzymes are: 1. Primase 2. DNA Polymerase 3. DNA Ligases. Enzyme # 1. Primase: A primase is an enzyme which makes the RNA primers required for initiation of Okazaki pieces on the lagging strand. Primase activity needs the formation of a complex of primase and at least six [...]
Some of the important functions of Nucleus are as follows: J. Hammerling in 1934 demonstrated that the nucleus controls the functions of the cells and ultimately the characters of the individuals by conducting experiments on Acetabularia, a unicellular marine alga. Acetabularia has a stem between 3 and 5 cm long and a cap 1 cm in diameter. The nucleus is [...]
