Central Dogma
DNA → RNA → Protein
DNA vs RNA
DNA has deoxyribose; RNA has ribose
Bonds
Hydrogen bonds hold base pairs
Helicase
Unwinds DNA
Primase
Makes RNA primers
DNA Polymerase III
Builds DNA
DNA Polymerase I
Replaces primers
Ligase
Joins fragments
DNA gyrase
Relieves tension
Leading strand
Is continuous
Lagging strand
Forms Okazaki fragments
Silent mutation
No change
Missense mutation
Different amino acid
Nonsense mutation
Stop codon
Frameshift mutation
Insertion/deletion shifts reading frame
mRNA
Carries info
tRNA
Brings amino acids
rRNA
Forms ribosome
Post-transcription
5' cap, poly-A tail, splicing
