proteins can act on central dogma by - ANSWERS mediating regulation of
transcription
RNA and protein processing
translation
RNA can function on the central dogma via - ANSWERS RNA processing
mediation of transcription and translation
S strain - ANSWERS pathogenic
R strain - ANSWERS non-pathogenic
heat killed S strain + R - no components destroyed - ANSWERS mouse dies, live
S strain recovered
heat killed S strain + R - polysaccharides, lipids, RNA, or protein destroyed -
ANSWERS mouse dies, live S strain recovered
heat killed S strain + R - DNA destroyed - ANSWERS mouse lives, no live S
strain recovered
,to transform R strain to S strain you need - ANSWERS intact DNA
DNA X pattern indicates - ANSWERS helix
thick top and bottom of DNA Xray crystallography indicate - ANSWERS regular
pattern of 10 stacked bases
distance between hatches in DNA Xray crystallography indicate - ANSWERS
one turn of helix is 34 A
thicker hatches to the outside of DNA Xray crystallography indicate - ANSWERS
phosphates are on the outside
measurement from center to top of DNA Xray crystallography indicate -
ANSWERS 3.4 A distance between stacked bases
which nt group has two rings - ANSWERS purine
smaller word = bigger structure
1' Carbon - ANSWERS attached to the nitrogenous base
2' Carbon - ANSWERS determines ribose or deoxyribose based on presence of
oxygen here
, 3' Carbon - ANSWERS hydroxyl group that reacts with phosphate of next group
to link chain
4' Carbon - ANSWERS closes ring
5' Carbon - ANSWERS phosphate attached, reacts with 3' OH of other base to
form chain
at cellular conditions, the phosphate of nt - ANSWERS loses H to give DNA the
negative charge
which nitrogenous base pair has a triple hydrogen bond - ANSWERS G+C
more specific groove - ANSWERS major - 4 atoms vs minor's 3 atoms
how do DNA binding proteins recognize the groove - ANSWERS atoms
associated with the bases will change order based on which strand of DNA they're
on
B DNA - ANSWERS right handed
10bp per turn
wide and deep major groove
