For the last question about advantages and disadvantages I put -
Advantages - your own stem cells so less likely to be recognised as foreign so less likely to be rejected
Also, using the diagram I said that there were some stem cells collected therefor they could be used to help treat the disease
Disadvantages- embryonic stem cells are potential human life
- a donor egg is still required to fuse with the body stem cell therefor still needs a donor
- think you could also say it is expensive

What do you guys get for the molecule that makes up genes? I did a stupid thing and wrote 'bases (protein molecule)' which makes no sense but desperate times.. :biggrin:

My friends are saying it was DNA molecule?

Fairly sure this is right.

One was 605 per 500cm3, and of which you needed 1000 for daily intake. The other was 4.5 per 500cm3, of which you needed 2.4 for daily intake.

I believe the answer is somewhere around 559/560.
