Let us make an in-depth study of the synthesis of RNA:- Learn about- 1. Process of RNA Synthesis 2. Transcription in Prokaryotes and 3. Transcription in Eukaryotes. Genes are expressed by transfer of genetic information from DNA to RNA. From RNA the information is used for synthesizing proteins. RNA is synthesized from a portion of one strand of DNA, which [...]
Let us make an in-depth study of transcription (synthesis of RNA) in prokaryotes and eukaryotes. Transcription in Prokaryotes: In prokaryotic organisms transcription occurs in three phases known as initiation, elongation and termination. RNA is synthesized by a single RNA polymerase enzyme which contains multiple polypeptide subunits. In E. coli, the RNA polymerase has five subunits: two α, one β, one [...]
The upcoming discussion will update you about the differences between replication and transcription. Replication: 1. Occurs in the S phase of cell cycle. 2. Catalyzed by DNA polymerase enzymes. 3. Deoxyribonucleoside triphosphates (dATP, dGTP, dCTP, dTTP) serve as raw materials. 4. Takes place along both the strands of DNA. 5. Involves unwinding and splitting of the entire DNA molecule (chromosome). [...]
