What occurs to the two strands of the parental duplex during replication? - they separate Is replication conservative, semi-conservative, or dispersive? - semi-conservative What does it mean to be conservative? - the original DNA is kept and an exact replica is made What does it mean for DNA is be dispersive? - parts of the old and new DNA are chopped together What does it mean for DNA to be semi-conservative? - each new daughter DNA is one old strand and one new strand What was the experi...

What are the 4 nitrogenous bases? Which pair together? Correct Answer-adenine (A), thymine (T), cytosine (C), guanine (G) A->T, C->G What are the issues with these combinations: 1.) Pyrimidine + Pyrimidine = 2.) Purine + Purine = 3.) Pyrimidine + Purine = Correct Answer-1.) width of DNA too narrow 2.) width of DNA too wide 3.) width of DNA consistent with X-ray model Which bases are purines and which are pyrimidines? Correct Answer-purines: A,G pyrimidines: T,C What are...

- Do all viruses need a primer for their genome replication? Correct Answer-o No, some viruses are able to be self-prime with their own genome. Others use RNA primers and some use protein primers. - Describe how viruses in class VI and VII replicate their genomes. Correct Answer-o Class VI: (+) ssRNA to (-) ssDNA to dsDNA to (+) ssRNA using viral RNA-dependent DNA polymerase and host DNA-dependent RNA polymerase o Class VII: dsDNA to (+) ssRNA to (-) ssDNA to dsDNA using host DNA-dependent R...

Structure of DNA CORRECT ANSWER 5'-->3' Anti-parallel 1 ring=pyrimidine 2 ring=purine A(2) + T(1) 2 H-bonds G(2)+C(1) 3 H-bonds *G and C have 3* DNA Replication CORRECT ANSWER Semi-conservative DNA Pol replicates 1000nt/second *errors only 1/10billion bp Why does the origin (oriC) have runs of A:T base pairs? CORRECT ANSWER Easy to break apart, only 2 H-bonds
