Anyone know what this is and how it differs from Helicase? Their functions sound the same to me -__-

For the MCAT, the polymerase plus all of the accessory proteins like the helicase that come together to form a complex is known as the replisome.

So it's easier to think about the replisome as like a big tool box which carries certain tools such has helicase, DNA Pol1 , etc.

It is essentially a complex that carries various proteins including helicase.

Think of it like this: The polymerase, gyrase, helicase, and other various initiation factors etc. do NOT act in isolation of each other. Rather, they come together and complex in what is known as a replisome.

 

[DrknoSDN]

"The replisome is composed of a number of proteins including helicase, RFC, PCNA, gyrase/topoisomerase,SSB/RPA, primase, DNA polymerase I, RNAse H, and ligase."
The replisome is the combination of all the smaller functional subunits.
