AP Transcription

In eukaryotic cells, transcription cannot begin until 

• the two DNA strands have completely separated and exposed the promoter.
• several transcription factors have bound to the promoter.
• the 5' caps are removed from the mRNA.
• the DNA introns are removed from the template.

What is the flow of genetic information in cells from DNA to protein? (Central Dogma)

• RNA to DNA to protein
• DNA to RNA to protein
• protein to DNA to RNA
• RNA to protein to DNA

Where does transcription occur in eukaryotic cells?

• Nucleus
• Ribosome
• Cytoplasm
• Rough E.R.

RNA polymerase moves in which direction along the DNA?

• 5' to 3' 
• 3' to 5' along the template strand
• 3' to 5' along nontemplate(coding) strand
• 5' to 3' along the template strand

The parts of a gene that do NOT code for amino acids in a protein are called

• introns
• exons
• codons
• anticodons

Which of the follwoing best describes the significance of the TATA box in eukaryotic promoters?

• it is the recognition site for a specific transcription factor
• it sets the reading frame of the mRNA
• it is the recognition site for ribosomal binding
• it signals the end of the nucleotide sequence of the gene

Transcription in eukaryotes requires which of the following in addition to RNA polymerase?

• the protein  product of the promotor
• start and stop codons
• ribosomes and tRNA
• several transcription factors

What is the function of the poly-A tail in mRNA?

• to add modified guanin to the 3' end of the mRNA
• to indicate the site of translational termination
• to code for the binding of RNA polymerase to the DNA
• to help protect the mRNA from degradation by hydrolytic enzymes 

Which enzyme is responsible for matching the mRNA bases to the DNA template during transcription?

• DNA Ligase
• Ligase
• DNA Polymerase
• RNA Polymerase

In eukaryotes, functional messenger RNA molecules are made from

• exons spliced together after introns are removed
• introns spliced together after eons are removed
• exons spliced together with introns
• long pieces of RNA shortened by the Dicer enzyme
