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 [...]
The following points highlight the top four examples of cytoplasmic inheritance in eukaryotes. The examples are: 1. Sigma Virus of Drosophila 2. Milk Factor in Mouse 3. Maternal Sex Ratio Condition in Drosophila 4. Cytoplasmic Male Sterility (CMS). Cytoplasmic Inheritance: Example # 1. Sigma Virus of Drosophila: Normally, Drosophila is anesthetized by CO2 without any after effect. But certain strains [...]
