what was the question?

It was the one MC before the sticky end one (btw is it 4 phosphodiester bonds??)
Are the statement correct:
Ligase to cut DNA -- no
Restriction enzyme to stick DNA -- no
Can't remember 3rd one
yh
i think was none too

I think it was is something a vector but I put none because plasmids was the vector
What was the role of ATP in neurone transmission? I was so confused
How did you investigate whether the plant species was long hour day or short day

ATP used for active transport of K+ and Na+ by protein pumps to restore resting potential

That’s what I thought - but people are saying exocytosis and channel proteins

But those transports don't use ATP

Exocytosis does use ATP. However, I put the same as you sodium and potassium pumps for active transport.
the only reasoning i could think of exocytosis related to the neurone is in the presynaptic knob for vesicles containing ca2+ we dont know how the mark
scheme is maybe both could be right
