Answer:
10x
Question: high power lens
Answer:
40x
Question: oil immersion lens
Answer:
100x
Question: compound light microscope
Answer:
multiply objectives magnification by 10x
Question: disecting microscope
Answer:
magnification does NOT get multiplied
Question: hypotonic solution
Answer:
solute is more inside the cell than outside
Question: hypertonic solution
Answer:
solute is more outside the cell than inside
Question: crenation
, Answer:
animal cells in hypertonic
Question: plasmolysis
Answer:
plant cells in hypertonic
Question: lyse
Answer:
animal cells in hypotonic
Question: turgid
Answer:
plant cells in hypotonic
Question: reduced
Answer:
colorless
Question: oxidized
Answer:
has color
Question: chromatography
Answer:
most soluble in organic solvent mixture travels the farthest
Question: nucleotide in DNA contains
Answer:
deoxyribose sugar, phosphate group, nitrogenous base
Question: where phosphate is located
Answer:
5' end
Question: PCR
, Answer:
polymerase chain reaction
Question: Miescher
Answer:
1868; chromosomes could be broken down to elements found in proteins; carbon, nitrogen,
oxygen, and hydrogen
Question: Sutton
Answer:
1903 Mendel's factors were located on chromosomes
Question: Griffith
Answer:
concluded that virulent strain of pneumonia, even when killed, could somehow pass its
deadly characteristics to the non-virulent strain
Question: Oswald Avery
Answer:
DNA must be the genetic material! ; did NOT support hypothesis that protein responsible for
heritable traits, but DID support that DNA played this role
Question: Chargaff
Answer:
adenine always equals thymine and guanine always equals cytosine
Question: Chase and Hershey
Answer:
experiment with bacteriophage
Question: Watson and Crick
Answer:
realized nucleotide pairs containing the bases G and C were identical in shape to pairs
containing the bases T and A
Question: conservative replication
Answer:
, original double-stranded helix somehow codes for a completely new double helix while still
maintaing the original old double helix
Question: dispersive replication
Answer:
original double-stranded helix is broken apart into individual nucleotides. Original
nucleotides recombine with new nucleotides to make new double helices that are a
combination of old and new nucleotides
Question: semi-conservative replication
Answer:
original double-stranded helix is split apart lengthwise into single-stranded halves. Each
original strand combines with new strand to make new double helices that are combos of
old and new strands
Question: objective of PCR
Answer:
produce a large amount of DNA in a test tube starting from only a trace amount;
denaturation, annealing, extension
Question: diffusion
Answer:
movement of molecules from regions of higher concentration into regions of lower
concentration
Question: enzymatic rate
Answer:
time vs. absorbance
Question: pH 7
Answer:
highest enzymatic rate
Question: pH 11
Answer:
lowest enzymatic rate
Question: meiosis I
