Central Dogma
flow of information: DNA --> RNA --> protein
1 of 10
RNA
single stranded but can fold upon itself to form secondary structures
2 of 10
Transcription has 3 phases
initiation, elongation, termination
3 of 10
Initiation
RNA polymerase recognises + binds to promoter sequence on DNA
4 of 10
Elongation
RNA polymerase elongates nascent RNA in 5'-3' direction, antiparallel to template DNA
5 of 10
Nucleotides added by...
complementary base pairing
6 of 10
Substrates
hydrolysed as added, releasing energy
7 of 10
Termination
special DNA sequences + protein helpers terminate
8 of 10
Transcript
released from DNA
9 of 10
Primary transcript
called "pre-mRNA", processed to generate mature mRNA
