Week 2 - Transcription and Gene Expression

Front

Where does transcription occur in eukaryotic cells?

Back

Nucleus

Front

What region does TFIID recognize?

Back

TATA box

Front

What signals the end of transcription?

Back

Terminator sequence

Front

What dual functionality does TFIIH have during transcription?

Back

Unwind DNA and activate RNA Polymerase II via phosphorylation.

Front

Which base is found in RNA but not DNA?

Back

Uracil

Front

What is the role of RNA Polymerase in transcription?

Back

RNA Polymerase synthesizes RNA from a DNA template.

Front

What is the function of the 5’ cap in mRNA?

Back

The 5’ cap protects mRNA from degradation and assists in ribosome binding.

Front

What is the purpose of the Poly-A tail in mRNA?

Back

The Poly-A tail enhances the stability of mRNA and aids in its export from the nucleus.

Front

What is a promoter in the context of transcription?

Back

A promoter is a DNA sequence that initiates transcription of a gene.

Front

What is the significance of the TATA box?

Back

The TATA box is a core promoter element that helps position RNA Polymerase II.
