All the bacteria, regardless of whether that had the plasmid or not.
Only the bacteria that contained the plasmid.
Only the bacteria that lacked the plasmid.
Yes, because their use of RNase would tell them whether RNA was critical.
No, because the phage RNA would incorporate both [32P] and [35S].
No, because the phage RNA would NOT incorporate either [32P] or [35S].
Yes, because, like DNA, the phage RNA would incorportate [32P] and not [35S]
A. Levene’s data implied the nucleotides were randomly assembled in cells but Chargaff proved they were in a specific order.
B. Chargaff proved that each species had different values for each base (although within species A=T & G=C), suggesting that DNA was different between them.
C. Levene’s data showed there wasn’t enough DNA in cells to encode all the necessary information but Chargaff disproved this.
D. Levene found that RNA & DNA used the exact same nucleotides while Chargaff proved that they didn’t.
Some of the S strain bacteria came back to live after acquiring some fragments of the R strain.
One R strain bacterium must have spontaneously mutated to become virulent.
Some of the R strain bacteria took in a fragment of the S strain DNA that encoded for synthesis of the polysaccharide coat.
Some of the R strain bacteria took in a fragment of the S strain DNA that encoded for ampicillin resistance.
The R strain surrounded itself with some of the polysaccharide coating from the dead S strain.

There is significantly more DNA pol I in each cell.
E. coli don't have DNA pol III.
DNA pol III does not work in a cell-free, in vitro DNA synthesis system.
He did find DNA pol III but called it the Kornberg enzyme.
The 5' to 3' polarity restriction in polymerization.
Discontinuous helicase activity.
None of the above
In situ hybridization
There is no reason. It is pure chance but has been conserved over time.
A's and T's are more easily recognized by the proteins of the replisome
They make up the restriction site recognized by the restriction endonuclease
They are easier to pry apart (i.e. require less energy).
DNA is always heavier because of the de-oxyribose in the nucleotides
RNA absorbs more UV light because it is single-stranded
Uracil absorbs more UV light because it contains more nitrogen.
RNA is less-stable so degrades more easily.
It forms left-handed helix.
It uses only purines
In RNA, the amount of G's may not equal the amount of C's
It is not negatively charged
None of the above

Have more histones in their chromain
May have slightly more or less than 10.4 base-pairs per helical turn
Is only found in mitotic chromosomes
Is never found naturally in cells.
Forms a left-handed helix
To prime the mRNA
To unwind the DNA helix during replication
To facilitate elongation
To bind strongly to the promoter
To mediate termination
They occur only in gametes
More than one chromosome is affected.
They change a nucleotide's base-pairing, causing it to base-pair with a different nucleotide
They not only affect one codon but all codons downstream.
