I actually failed my molecular biology course, and I’m still a little salty about that. I understood molecular biology. I didn’t memorize stuff like the order in which subunits bind to assemble the pre-replication complex.
After ORC1-6 bind the origin of replication, Cdc6 is recruited. Cdc6 recruits the licensing factor Cdt1 and MCM2-7. Cdt1 binding and ATP hydrolysis by the ORC and Cdc6 load MCM2-7 onto DNA.
Note that they’re numbered but the numbers aren’t related to the order in which they act. I don’t need to know that. No one who doesn’t do research specifically on the pre-replication complex needs to know that.
(Excuses, excuses…)
I know people whose grants have been put on hold and these people don’t even know if they have health insurance anymore, since grant money pays for that too. This is wild.
