,In the 1920's, one of Griffith's pneumococcus experiments demonstrated the process of
transformation that suggested DNA was the transforming factor, not protein. What was
it? - Heat-killed smooth strain + Live rough strain injected into mice resulted in death

Why were Avery, MacLeod and McCarty's experiments in the 1940s considered more
humane AND more direct evidence to support DNA as the transforming factor than
Griffith's experiments? - No mice were used, and 1 macro-molecule of the S strain was
added to the live R strain at a time

In Hershey and Chases's bacteriophage experiments, after centrifugation, results
showed most of the P32 in the ______, where the bacteria resided. However, a trace of
P32 was found in the ______, due to _________ - Pellet, Supernatant, bacteriophage
that did not start the infection process.

One strand of DNA is 5' -AGGCCTTA- 3'. What is the DNA sequence of the opposite
strand? - 3' -TCCGGAAT- 5'

The order of chromatin folding from widest to narrowest width is... - radial loop, folded
loop, solenoid, nucleosome

What types of amino acids in histones are most responsible for the binding to DNA?

Neutral (no charge) amino acids

Polar amino acids

Positively charged amino acids

Negatively charged amino acids - positively charged amino acids

Which of the following statements is true?

a nucleosome has 8 histones with 1 histone cross-linker to hold the coiled DNA

a solenoid contains 6 nucleosomes per turn

a folded loop is held together by non-histone proteins

all of the above - ALL OF THE ABOVE

A(n) ________ is at the 5' end, whereas a(n) ________ is at the 3' end of a single DNA
strand. - Phosphate group, hydroxyl group

If guanine makes up 23% of the nucleotides in a sample of DNA then thymine would
make up what percent of the bases? - 27%

, In nucleic acids, the purine (double-ring) bases are _______, whereas the pyrimidine
(single-ring) bases are _______. - Adenine and guanine, thymine, cytosine, and Uracil

A defect in the chloride transporter protein prevents it from embedding in a cell
membrane of a lung cell, thus creating a faulty chloride channel. This causes a salt
imbalance in lung cells. This description is at which level of genetics?
