1962-Physiology or Medicine For their joint discovery of the structure of DNA
James Watson, Francis Crick, Maurice Wilkins
100
Darwin was influenced by this theory which describes how changes on the earth's surfaces can result from continuous actions still operating today.
Gradualism
100
from the Latin for "little net" contains a network of membranes called cisternae that are continuous with the nuclear membrane
endoplasmic reticulum
100
both molecules have a magnesium atom at the center of the light absorbing head a hydrocarbon tail but differ only in the a functional group
Chlorophyll A and B
100
the most surprising finding of this study was that the human genome is made up of only 20-25,000 protein coding genes much less than expected
the human genome project
200
2003-Chemistry Peter Ager for his discovery of this proteins that specifically facilitate the diffusion of water across the membrane
aquaporin
200
the differential success in reproduction results in certain alleles being passed to the next generation in greater proportion s than other.
Natural Selection
200
produces hydrogen peroxide (H2O2) and convert it into water
peroxisome
200
a light harvesting complex made up of pigment molecules bound to particular protein
photosystem
200
a spectrophotometer measures the relative amount of light of different wave-lengths absorbed and transmitted by one of these molecules
pigment
300
1982-chemistry Tom Cech for announcing that this molecule cut and rejoined chemical bonds in the complete absense of proteins
RNA
300
speciation which occurs when a population encounters a multiplicity of a new ecological niches
Adoptive radiation
300
microfilaments maintain the shape and form the cleavege furrow during cell division the are made of 2 interwinding strands of this protein
actin
300
a metabolic pathway that consumes oxygen, releases carbon dioxide and generates no APT occurs during hot, dry, days with the stomata closed
photorespiration
300
scientist frequently use these atoms who's nucleus spontaneously decay to trace metabolic processes or to locate substance inside the cell
radioactive isotopes
400
for discovering the DNA carries genetic info, this nova scotia born scientist was nominated every year from 1946 until his death, but never won
Oswald Avery
400
while not introduce new genes, this process creates most of the genetic variations allowing adaptation to occur in sexual repro. organisms
sexual recombination
400
to coordinate activities with the extracellurar enviro. animal cells have tight junctions, and desmosomes. plant cells have these
plasmodesmata
400
because the calvin cycle uses more ATP than NADPH this alternative path may be used to produce additional ATP but no NADPH
cyclic electron flow
400
a medical research tool that displays pairs of condense chromosomes in an effort to screen for abnormal chromosomes defects
karyotype
500
1958/1980-chemistry for his work on the structure of protein, especially that of insulin. one of that of only four people to win twice
Frederick Sanger
500
changes in bases sequences of regions of DNA may occur at rates constant enough to date past evolution events, this time piece is referred to as
molecular clock
500
type of transport across the plasma membrane where one solute's "downhill" diffusion drives the others "uphill" transport
cotransport
500
a protein in the electron tranport chain that receives electron from the mobile plastoquinone causing the tranlocation of H+
cytochrome
500
like arthropods surgeons use this polysaccharide to make a strong and flexible surgical thread that decomposes after the wound heals
chitin
