Name this structure
Adensoine Triphosphate
Which Strep Pneumoniae strain secretes a capsule?
S
Did the mice live or die with injected with s-strain?
The mouse died
Did mouse live or die with injected heat killed s-strain?
Mouse survived
Did mouse live or die with Live type-R and heat-killed injected type-s; what does this indicate?
The mouse died; bacterial transformation
What experiment did Avery, Mcleod, and Mccarty perform?
Used deconstructive enzymes for proteins [Protease], RNA [RNase|, and DNA on cell extracts from type-s to determine which molecule was responsible for the transformation from dead-s to Live-r. They determined that uptake was only impacted when the s-strain was treated with DNase indicating that DNA was responsible for the information that was exchanged.
What evidence did Hershey and Chase provide toward DNA research?
Use of radioisotopes to distingush DNA presence from Proteins when a bacteriophage was introduced to e. coli
What radioisotope lablled DNA?
P-32
What radioisotope labelled proteins?
S-35
What distinguishes Dexoyribose from Ribose? DRAW
Deoxyribose is missing an oxygen at 2'; SEE COMPARISON
What is the difference between a nucleotide and a nucleoside?
a nucleotide includes the phosphate group(s) and a nucleoside is just a pentose sugar and base
Order dna structure from in increasing complexity [Chromosome, Nucleotide, Amino Acid, DNA strand, Double Helix]
Amino Acid, Nucleotide, DNA strand, Double Helix, Chromosome
Name 3 components of a Nucleotide
1 Phosphate, 1 Pentose Sugar, 1 Nitrogenous Base (Purine or Pyrimidine)
Name Purines
Adenine and Guanine
Name Pyrimidines
Cytosine, Thymine, Uracil
Name this Nucleoside
Guanosine
What is the bonding type between base pairs?
Hydrogen
What is the average alpha-helix bp length?
10bp; 20 bases
What does Chargaff's rule indicate about relative percentages of base pairs?
%A=%T; %G=%C
Which way does the helix turn?
Right-Handed, Clockwise
What does antiparallel mean in referece to DNA strand orientation?
In a double sided DNA strand, the complementary strands are oriented in opposite directions with one side exhibiting a 5' to 3' and one side 3' to 5'
How many H bonds between A/T?
2
Explain what base stacking means?
base stacking is the structure of the helix being base pairs stacked on top of eachother
What is the complementary pairing to CGTAAGCGCTAATTA
