24. replication and recombination** Flashcards
1
Q
how is DNA replicated in bacteria?
A
- a single chromosome replicated in 42 min
– started from single origin of replication and proceeding around circle bidirectionally
2
Q
how is the process initiated?
A
- occurs at specific nucleotide sequence
– at ori
– when various proteins bind to begin replication - some proteins that bind to origin of replication are important in making single-stranded regions of DNA accessible for replication
– chromosomal DNA wrapped around histones/histone-like proteins and is supercoiled
