Biology rest Flashcards
George Beadle and Edward tatum did what research
Made genes defective
Watson and Crick experiment
Antiparalel, complementary base paring DNA
Measels and stah research
DNA replication by semiconservative
Hersen and chase
DNA carry genetic information not protein
Srb Horowitz experiment
one gene one enzyme hypothesis
Redundant genetic code
more than 1 way to get the same codon
Unambiguous Genetic code
1 code only for 1 amino acid
misense point mutation
1 mistake alter Dif amino acid
Conservative genetic code
Last base does not matter
frame shift mutation
changes the whole thing
silent mutation
you dont see it. does not change final protein
Non sense mutation
changes codon into stop codon
Chromosome mutations
Change chromosome number polypoid or aneuploid
DNA replication requires energy name
endergonic and make more phosphodiester bonds exergonic
Topoisomerrase function
Cut and release tension
SSBP
dont let the helix clpse up again
DNA plymerase function
an enzyme that copies DNA by adding nucleotides to a DNA strand
CAtalize DNA. polymer of dna
