Hey I'm totally new to this event. So will we know exactly which protein will be build on site or nah

So since this year's topic deals a lot with physics stuff(motion/velocity/wavelength), its going to be more of a physics event?

also what is Dual force?

hey anyone knows where can we study this event?

also, is this event more of a chemistry event, or biology event?

the first reason is correct!!

The second one im looking for is that alpha glucose is largely helical while beta glucose is straight and unbranched.

kk ur turn!
