Introduction to Gene: Mendel's, (1865) experiments with Garden pea plant showed that certain hereditary "factors" were concerned in determining the appearance of certain morphological traits.

Starts at the beginning of replication. 3. Progresses in on direction, i.e., towards the replication fork. 4. Synthesis of DNA takes place continuously. 5. In vivo need no RNA primer. 6. Only DNA [...]
The following points highlight the four main replications of DNA. The replications are: 1. Plasmid 2. Mitochondrial DNA 3. Kinetoplast DNA 4. Chloroplast DNA. Replication # 1. Plasmid: In addition to the nucleoid DNA, the cytoplasm of bacterial cell contains one or more extra chromosomal mini-circular DNA duplexes which are known as plasmids that can replicate independently of the nucleoid [...]
