Transcription

What must happen to mRNA in eukaryotes before it leaves the nucleus?

• It needs to be processed

• It needs to be degraded

• It needs to be translated

• It needs to be replicated

Which of the following is NOT a stage of transcription?

• Initiation

• Elongation

• Termination

• Translation

What is the first step in the process of transcription?

• Termination

• Elongation

• Initiation

• Replication

What happens to the RNA polymerase after it reaches the terminator?

• It continues synthesizing RNA.

• It detaches from the DNA.

• It starts synthesizing DNA.

• It binds to another RNA strand.

What is the function of the 5' cap in mRNA processing?

• Protects mRNA from degradation

• Initiates translation

• Adds amino acids

• Removes introns

Which of the following is NOT a part of mRNA processing?

• Splicing

• Adding a 5' cap

• Adding a poly-A tail

• DNA replication

Which of the following is a characteristic of mature mRNA?

• Contains introns

• Lacks a 5' cap

• Has a poly-A tail

• Is double-stranded

Where does transcription start in eukaryotes?

• Cytoplasm

• Nucleus

• Mitochondria

• Ribosome

Which enzyme is responsible for transcription?

• DNA polymerase

• RNA polymerase

What is the role of RNA polymerase?

• To replicate DNA

• To synthesize RNA

• To degrade proteins

• To transport lipids
