DNA Transcription and Translation

transcription results in the creation of

• mRNA

• tRNA

• rRNA

• mDNA

In eukaryotes, which RNA polymerase makes rRNA?

• RNA polymerase I

• RNA polymerase II

• RNA polymerase IV

• RNA polymerase III

Which of the following codons is the mRNA start codon that initiates translation?

• UGA

• AUG

• UAA

• UAG

Which of the following best describes the key function of helicases during transcription?

• Cleaving methyl groups from an unwound DNA strand.

• Catalyzing the interaction between transcription factors and the DNA strand.

• Re-annealing of two DNA strands once transcription and translation processes are complete.

• Separation of two strands of DNA; "unwinding" gives polymerases access to the strand.

• Relief of tension in the DNA strands to prevent breakage.

Transcription factors that are the first to bind DNA in heterochromatin regions, often promote euchromatin formation, and recruit other transcriptional machinery to promote transcription are best known as which of the following?

• Pioneer factors

• Histone demethyltransferases

• DNA Polymerases

• Co-factors

• RNA holoenzyme

Before RNA polymerase can initiate transcription, this protein must bind to it, creating the RNA polymerase holoenzyme and allowing for the initiation of transcription.

• Sigma factor

• Activator protein

• Helicase

• Topoisomerase

• Beta factor

Which polymerase is involved in transcribing ribosomal RNA

• RNA polymerase I

• RNA polymerase III

• DNA polymerase IV

• RNA polymerase II

Which of the following are methods for termination of transcription in prokaryotes?

I. Release factor binding

II. Rho-mediated termination

III. Hairpin loop (stem loop) formation

• I, II, and III

• II and III

• I only

• III only

A Cell builds its proteins from the Instructions encoded in its

• A. Cytoplasm

• B. Cell Membrane

• B. Cell Membrane

• D. Lysosome

• E. Genome

What process occurs before the other?

• Transcription and then Translation

• Translation and then Transcription

• Translation and then Polymerization

• Transcription and then Ionization
