In this article we will discuss about:- 1. Concept of DNA 2. Structure of DNA 3. Unusual Bases 4. Replication. Concept of DNA: DNA is present in the cells of all plants, animals, prokaryotes and in a number of viruses. In eukaryotes (e.g., Escherichia coli, a bacterium) the genetic material consists of a single giant molecule of DNA about 1,000 [...]
The following points highlight the top four experimental evidences for DNA as genetic material. The experimental evidences are: 1. Transformation 2. Bacteriophage Infection 3. Transduction 4. Biochemical Analysis. Experimental Evidence # 1. Transformation: The genetic recombination in which naked DNA from one cell can enter and integrate in another cell is referred to as genetic transformation. Experiments on genetic transformation [...]
