Let us make an in-depth study of the DNA damage types and repair mechanisms. The damage types of DNA are: 1. Simple Mutations 2. Deamination 3. Missing Bases 4. Chemical Modification of Bases 5. Formation of Pyrimidine Dimers (Thymine Dimers) and 6. Strand Breaks. The various DNA repair mechanisms are: 1. Direct Repair 2. Excision Repair 3. Mismatch Base Repair [...]
The following points highlight the three natures of genetic material. The natures of genetic material are:- 1. Bacterial Transformation 2.Transduction and 3. Transfection. Genetic Material Nature # 1. Bacterial Transformation: The experiments conducted on pneumonia causing bacteria by Griffith made a milestone observation which proved that DNA is the genetic material. The experiments by Griffith performed in 1928 are also [...]
The upcoming discussion will update you about the differences between somatic hybridization and sexual hybridization. Somatic Hybridization: 1. It involves fusion of somatic cells. 2. It leads to the production of allotetraploid plants. 3. There is equal contribution of cytoplasm from both parents. 4. Segregation does not occur. 5. Wide crosses can be easily made Sexual Hybridization: 1. It involves [...]
