Gene Expression and Regulation
Central Dogma
DNA
RNA
Polypeptide
Nitrogenus base
Timin
Cytosine
Pyrimidine
single ring
Guanin
Purine
double ring
Adenin
A=T, C three bonds G (H bonds)
since G C bonds are stronger if there is less of them melting point is low if there is more of them melting is harder
phospahete group
Pentose sugar (deoxyribose)
Read 3' to 5'
Synthesized 5' to 3'
for retro viruses
RNA
DNA
RNA
Polypeptide
ribose instead of deoxyribose
Eukaryotes
nucleus
multiple linear
Prokaryotes
nucleoid
Double strended circular
differences
DNA replication in
DNA Structure
Gene expression stuff
Replication
Helicase
unwinds DNA
breaks h bonds between nitrogenus bases
other side got super coiled
Topoisomerase
Cuts DNA strends
unwind coils
repair DNA
Primase
synthesizes RNA Primer
Puts it on DNA( with uracil)
DNA Polymerase
continues what RNA primer left behind
continuously on leading strand
discontinuously on lagging strand
Ligase
seals the discontinuety
Transcription
Template Strand (noncoding, minus, antisense)
the strand being read
RNA Polymerase
cuts dna to half
completes the strand with an rna strand exactly same to preveous dna
Promoter
The site RNA polymerase bonds to start transcription on dna
