The autocatalytic function is the capacity of DNA to make a copy of itself. This capacity is known as replication. Watson and Crick proposed a mechanism of replication on the basis of its double helical structure. According to them, the two strands were capable of unwinding and separating and acting as templates during the synthesis […]
The most conclusive evidences in support of DNA as the genetic material comes from different avenues of approach on microorganisms – transformation of bacteria and transduction involving bacteriophages. 1. Griffith’s Experiment and Bacterial Transformation: In 1928, Frederick Griffith, an English bacteriologist conducted transformation experiments on two strains of bacterium, Streptococcus pneumoniae (Diplococcus). The two strains […]
In this article we will discuss about:- 1. Meaning of Transcription 2. Mechanism of Transcription 3. Transcription in Eukaryotes. Meaning of Transcription: Transcription is the process by which a complementary RNA strand is synthesised from a specific region of DNA. The three different types of RNA are transcribed from different regions of DNA. The genes […]
