why cant dna completely unwind the whole strand before starting to build for the new one
during DNA replication, the helicase unwinds the double helix **while** new strands are synthesized. but the lagging strand needs to go the opposite way in the fork, meaning that it must wait for the portion to unwind before slipping in the okazaki fragment.
so why can't it just unwind the whole double helix and separate the two templates? wouldnt the supposed lagging strand be able to synthesize continuously this way?
