protien sysnthesis
sequence of codons (AAA) on mRNA determine sequence of amino acids in protien being synthesized
sense codes
61 amino acids
stop codons
3
UAA UAG UGA
start codon
AUG
ribosome
site of translation
direct the orderlt bindin of tRNA to codon and assembly of amino acids to make protiens
move along mRNA in a 5'-3' direction
tRNA
recognize specific codon and transport amino acids
translation steps
ribosom tRNA(UAC) and mRNA(AUG) come together
psite
a site
esite
peptide bonds cont
p site
where the first tRNA sits
a site
second codon of mRNA pairs with tRNA carrying amino acid- joined by peptide bonds
ribsome moves
along the mRNA
e site
first trna is in the esite
second and thrid amino acid
joined by a peptide bond
3 and 4, 4 and 5 and so on
until ribosome reaches stop codon
stop codon
polypeptide released
ribosome comes apart tRNA released and polypeptide becomes a new protien
mendel
1865 studied pure breeding in pea plants
interested in genetics
sutton
meiosis in grasshoppers
observed chromosomes separate hereditary material during meosis
morgan
used fruit flies to develop genetics and discovered sex-linkage
students developed techniques of mapping genes on chromosomes
griffith
discoverd transformation
genetic transfer in microorganisms
nonpathogenic strain is transformed into a thogenic strain and killed the rat
living nonencapsulated and heat killed encapsulated bacteria caused the diseasd
genetic recombination
exchange of genes between two dna molecules to form more combiations of genes on a chromosome
delbruck
develpoed and taught biologists methods to analyze bacteriophage; virus of bacteria
deadie and tatum
develped neurospora -experimental organism
1 gene 1enzyme hypothesis
tatum and lederburg
discovered conjugation in bacteria
meischer
isolated DNA from the nuclei of cells obtained frm pus of surgical bandages
contained nitrogenous chemicals, sugar and phosphate
avery and maclead
found transforming factor to be DNA by using enzymes
capsule-carbohydrase-transformation
protien-protease-transformation
rna-rnase-transformation
not dna DNAase
hershey and chase
used 35s (protien)
32p (nucleic acid)- went into cells
watson and crick
xray cystallography to study DNA
made a model of dna
infered fuction leading o central dogma
