Thanks.

Thanks- this is really interesting. I couldn't though find a good definition of hemimethylated by doing a Google search. Do you happen to know of somewhere where I could find the definition?

Thanks. I think that I now have a better idea, but was wondering if is it known what regulates the DMTs?

Thanks.

How does DNA methylation occur- is there an enzyme that carries out the methylation? How is it regulated?

How does the CLOCK transcription factor sense light and how does it regulate Circadian rhythm for the body?

Once the B12/intrinsic factor complex gets endocytosed (by what kind of cells?) and into the blood stream, where does it go next? When does the complex get broken up?

How does vitamin B12 get absorbed by the body- through the small intestine and to the bloodstream- and once it is in the blood stream, where does it go?

So growing taller is an adaptation to get sunlight? That is very cool.

It isn't my plant, a friend asked me this question. I will try to find out more details.

So plants can last a really long time without sunlight but eventually will need more?

Basically, how does intrinsic factor work?
