Chapter 25 and 26 Activity

The central dogma of molecular biology states that information in DNA is expressed in the structure of:

• RNA

• Proteins

• Lipids

• Carbohydrates

The process of copying information from DNA to mRNA is called:

• Translation

• Replication

• Transcription

• Mutation

In eukaryotes, transcription takes place in the:

• Cytoplasm

• Ribosome

• Nucleus

• Golgi apparatus

Which enzyme is responsible for synthesizing mRNA during transcription?

• Helicase

• RNA polymerase

• Ligase

• Protease

The DNA strand that has the same sequence as the mRNA (except for U replacing T) is called the:

• Template strand

• Coding strand

• Anti-codon strand

• Non-coding strand

Which of the following is NOT a kind of RNA polymerase in eukaryotes?

• RNA polymerase I

• RNA polymerase II

• RNA polymerase III

• RNA polymerase IV

What is the function of the TATA box in transcription?

• It is a termination signal.

• It is an initiation signal.

• It codes for a protein.

• It is spliced out.

What is added to the 3’ end of mRNA during post-transcriptional modification?

• 7-mG cap

• Poly-A tail

• Introns

• Exons

Which of the following is the correct order of events in translation?

• Termination, Elongation, Initiation

• Initiation, Termination, Elongation

• Initiation, Elongation, Termination

• Elongation, Initiation, Termination

Which site on the ribosome holds the growing polypeptide chain?

• A site

• P site

• E site

• mRNA site
