What is the name of the enzyme used in the experiment by Weintraub and Groudine?
DNase
What is the name of the complex formed by DNA and histone proteins?
Nucleosome
What is the main reason why chromatin remodeling is necessary for gene expression?
To allow RNA polymerase to access the promoter
How does chromatin remodeling control gene expression?
By decondensing chromatin to activate genes
What is the role of the template strand during transcription?
Provide a complementary sequence for RNA synthesis
What is the primary function of RNA in the cell?
Encode proteins
During transcription, which direction is always followed by the RNA polymerase along the DNA strand?
5-3'
In the context of transcription, what is the function of the non-template strand of DNA?
Encoding proteins directly
What process directly follows transcription in the central dogma of molecular biology?
Translation
Which step concludes the 4-step process of bacterial transcription, according to the text?
Chain termination
Where does RNA polymerase bind during transcription initiation?
Double-stranded DNA sequence
What occurs during chain elongation in transcription?
Second round of transcription starts
Where is the promoter located relative to the start of transcription?
Immediately upstream (5’)
What is the function of the termination region in gene structure?
Regulates cessation of transcription
Which post-transcriptional process involves protecting mRNA from rapid degradation?
5’ capping
What is the main role of the coding region in a gene?
Contain information for protein synthesis
Learn about the key steps involved in the transcription process, from promoter recognition to chain termination. Understand how RNA polymerase binds to promoters and initiates transcription, followed by chain elongation and termination.
