-
DNA replication begins at the.....
origin of replication
-
can there be more than one origin of replication?
yes, there can be several hundred
-
DNA synthesis always occurs in what direction?
5' to 3'
-
what must happen first during replication?
enzymes must relax the structure of DNA
-
what initiates the synthesis of the daughter strands?
primers
-
what is the short, 200 nucleotide fragment that synthesises in the 3' to 5' prime direction?
Okazaki fragments
-
finishing up replication, what must occur?
any nicks remaining and all the Okazaki fragments must be ligated (joined)
-
the whole DNA fragment is transcribed... true or false... if false, what is not transcribed?
false, there is a promoter sequence to start, then the introns need to be spliced out
