In this article we will discuss about DNA as a genetic material. Transforming Principle: Frederick Griffith in 1928, carried out a series of experiments with Streptococcus pneumoniae (a bacterium that cause pneumonia). He observed that when these bacteria (Streptococcus pneumonia) are grown on a culture plate, some of them produce smooth, shiny colonies (S-type), whereas, […]
In this article we will discuss about:- 1. Experimental Proof of Replication of DNA 2. Enzymes for DNA Replication 3. Process of Replication of DNA. In addition to the double helical structure of DNA, Watson and Crick also proposed a scheme for DNA replication. According to this scheme, the two strands of double-helix would separate […]
The below mentioned article provides a note on DNA:- 1. DNA Chemistry 2. DNA Replication 3. Carrier of Genetic Information. DNA Chemistry: DNA is found to consist of thread-like particles of high molecular weight in isolated condition. A number of units called nucleotides become linked together and form the nucleic acid. A nucleotide is composed […]
