How does the DNA in a prokaryote differ from a eukaryote?

• Prokaryote has circular DNA, Eukaryotes has linear DNA

• Prokaryote has single stranded DNA, Eukaryotes has double stranded DNA

• Prokaryote has linear DNA, Eukaryotes has prokaryote DNA

• Prokaryote has double stranded DNA, Eukaryotes has single stranded DNA

Both eukaryotes and prokaryotes have plasmids. What are plasmids?

• large extra-chromosomal, double-stranded, linear DNA molecules

• large extra-chromosomal, double-stranded, circular DNA molecules

• small extra-chromosomal, double-stranded, circular DNA molecules

• small extra-chromosomal, double-stranded, linear DNA molecules

Which of the following demonstrates base pairing rules to 5' - CAGGT - 3'

• 3' - TGGAC - 5'

• 3' - GTCCA - 5'

• 5' - GTCCA - 3'

• 5' - CAGGT - 3'

Which of the following are NOT post-transcriptional modifications?

• 5' cap

• intron removal

• poly-A tail

• TATA box

During transcription, what is the relationship between DNA and RNA?

• Template DNA is the noncoding strand, RNA reads DNA in 3' -> 5' direction

• Template DNA is the coding strand, RNA reads DNA in 3' -> 5' direction

• Template DNA is the noncoding strand, RNA reads DNA in 5' -> 3' direction

• Template DNA is the coding strand, RNA reads DNA in 5' -> 3' direction

Where does translation take place in prokaryotes & eukaryotes?

• Prokaryotes - cytosol; Eukaryotes - cytosol or nucleus

• Prokaryotes - cytosol or rough ER; Eukaryotes - cytosol

• Prokaryotes - cytosol; Eukaryotes - cytosol or rough ER

• Prokaryotes - cytosol or nucleus; Eukaryotes - cytosol

What is the sequence of nucleotides on mRNA read in triplets called?

• anticodon

• codon

• triplet box

• wobble

How do retroviruses violate the central dogma?

• Retroviruses are responsible for using DNA to synthesize more viral RNA

• Retroviruses are pre-historic and existed prior to the central dogma

• Retroviruses use enzymes to make DNA from RNA & integrate into host DNA

• Retroviruses use host DNA to make viral RNA, then incorporate into host DNA

Identify which molecules bind to the promoter region

• Ligase

• DNA polymerase

• RNA polymerase

Which of the following are characteristics of Prokaryotic DNA?

• Single linear strand

• Single circular strand

• Multiple linear strands

• Plasmids

• Contains histones
