Genetic Material DNA A RNA
stores info in nouns
airements transmission from one source another mitosis meiosis
flow it can be used gem expression transcription translation e.g we access a
gem produce mrna which has a function gem protein
History
Watson Crick
i nobel for describing DNA structure
nucleotide H bonds to one another
C WI G
A w T
sugar phosphates exterior of molecule
Proteins us Nucleic Acids which is genetic material
people believed proteins be mon combos
Frederick Griffith's Transformation of Bateria
a rough strain
no capsule 00
white blood cells willattack
smooth strain polysaccharide capsule
big capsule or polysaccharides that allow it to avoid immune system
Griffith's Transformation of Bacteria
inject smooth strain into mom it gets sick
inject rough strain into mouse can cause pneumonia but immune system battles mouse healthy
his experiment kill smooth strain inject monee wi this heat shock bacteria
destroy plasma membrane soup or Dn
end mouse healthy
mix heat killed smooth wi alive rough
mouse sick
fatchuk 9 DNA of smooth takes over rough
if you extract Dna from mouse end w smooth strain
, Bacterial Transformation
1 Dead smooth strain releases DNA these Pieces
heat killed smooth strains soup of Dna

ygfg.gg sm h
am escaping from
2 Rough strain incorporates Dna into chromosomes
R gets the Dna from escaped s sms on

3 Rough strain has ability to produce bacteria can gather
floating statist
capsule become Smooth strain
becomes recombinant chromosome recombinant
chromosome
Evirmant naman
BASICALLY
start as k strain recombinant as rough gets Dna from smooth making
mouse sick
Avery MacLeod McCarthy
S strain but heat killed
Control no enzymes
Griffith's experiment replicated
mixed w R strain
mouse dies
smooth strain collected from mouse
Proteases enzymes for proteins
destroy protein
mouse dies be killed protein not nucleic acids
extract smooth DNA
Nucleases enzymes for Dna
destroys nucleicacids
mouse alive
no strain collected be rough strains killed by white bloodcells
BASICALLY
nucleic acids base materials for DNA
