The below mentioned provides a short note on the transcription in eukaryotes. Transcription occurs in eukaryotes in a similar way to prokaryotes. However, initiation is more complex, termination does not involve stem-loop structures and transcription is carried out by three enzymes (RNA polymerases I, II, III), each of which transcribes a specific set of genes and functions in a slightly [...]
In this article we will discuss about the Transcriptional and Post-Transcriptional Regulation of Gene Expression in Eukaryotes. Transcriptional Regulation of Gene Expression in Eukaryotes: The variation in the rate of transcription often regulates gene expression. Interactions between RNA polymerase II and basal transcription factors leading to the formation of the transcription initiation complex influence the rate of transcription. Other transcription [...]
In this article we will discuss about:- 1. Subject-Matter of Paramecium 2. Reproduction and Mode of Action of Paramecium 3. Origin of Paramecium. Subject-Matter of Paramecium: Sonneborn in 1943 found that Paramecium aurelia strains could be classified into "Killer" and "Sensitive" types. The killer strain secreted a toxic substance "paramecin" in the growing medium and this toxin was responsible for [...]
