And they are passed from one molecule to other in close proximity, so the chance of going elsewhere is probably low.

The electrons are passed through molecules in the membrane, so the oxygen is not much accessible to them.

I'm not sure it would be some slow decline. Because that would mean that some are compatible and some are not, while they all must be compatible to each other (more less)

if the alternative form is marker, than probably the normal form is not affected by cancer, is it?

It seems to be covered with wax or something alike, which will slow the decay, but I don't see really a reason, why should that be an advantage in reducing carbon footprint.

Anything is good idea if you're good (and lucky) enough to find a good lab.

Re: Totipotent Stem Cell From Molecular Components

A1: good luck, even Venter haven't managed that yet.

A3: and how will you get the protein? Are you really sure that the stemm cells contain all protein in the same amount?

A4: amplicon is the result of PCR. You need some template though, in your case probably the DNA.

I don't see why couldn't tetanus bacteria survive in dog vaccinated against rabies. However, the virus would be probably eliminated by dog's blood cells.

Replication of the leading strand begins at the origins and from those a continuous strand is produced until meeting replicating fork from another direction or end of the strand. The primer is removed by Okazaki fragment going in the other direction.

cytoplasm is liquid, so you cannot make it to form a membrane, unless you'd have two membranes holding the cytoplasm in between

First you use a sequence with the selection marker (as usually), but that is later excised by I-SceI cleavage and the second Red recombination.
