Question | Answer |
---|---|
Which molecule is bigger: DNA or RNA? | DNA |
in G0 phase, which of the following processes are occuring: replication, transcription, translation? | TRX, TRL (b/c proteins are still being made by those cells) REP is not happening b/c those cells are not dividing |
Name the nucleic acid: two rings, -NH2 | Adenine (purine) |
Name the nucleic acid: one ring, =O, -CH3 | Thymine (pyrimidine) |
Name the nucleic acid: one ring, =O | Uracil (pyrimidine) |
Name the nucleic acid: two rings, =O | Guanine (purine) |
Name the nucleic acid: one ring, -NH2 | Cytosine (pyrimidine) |
Which carbon does the nitrogenous base (A,C,G,T,U) attach to the ribose in RNA/DNA? | 1' |
Which carbon does the -PO4 attach to on ribose in RNA/DNA? | 5' |
What is significance of 2' carbon in RNA/DNA? | (OH) vs. no(OH) determines RNA or DNA |
How do the nucleic acids bind to each other in RNA/DNA (which carbons?) | the -PO4 of one nucleic acid binds with 3' carbon of the next nucleic acid |
Which is the major type of DNA: B-DNA or Z-DNA? | B-DNA |
What is the handedness of B-DNA vs Z-DNA | B= Right handed, Z= left handed |
Where do regulatory proteins bind on DNA? | Major and Minor grooves |
