Transcription Flashcards
1
Q
housekeeping genes
A
make cell components eg ribosomes all the time, everytime a cell divides
2
Q
prokaryotes vs eukaryotes gene expression
A
eukaryotes default genes switched off, prokary default switched on
3
Q
structure of a gene
A
promoter upstream (controls transcription) along with 5’ UTR, followed by initiation codon
4
Q
Initiation
A
RNA poly binds and pulls apart strands
5
Q
Transcription vs replication
A
transcription: goes back to being double stranded, translation doesn’t. 1 vs 2 strand template
6
Q
Which step of post- transcriptional processing last to occur
A
tailing
7
Q
Mechanism of spliceosomes
A
recognise intron-exon boundaries, form a loop
