My teacher told me to increase the risk assessement and ethical implication section to at least 1 page (i have written about third a page with 9 points). The problem is i cant think of anything else (and believe it or not i have seen other courseworks and i'm considered good if compared to them) So any ideas on what to write?! The materials are lead nitrate, copper nitrate, hydrogen peroxide, yeast, distilled water and pH 7 buffer! Thanks, this is really appreciated.

the genotypes of the F1 offspring are all AaBbCcDd. Assuming independent assortment of all four genes, what are the probabilities that the F2 offspring will be:

a) aabbccdd
b) AaBbCcDd
c) AABBCCDD
d) AaBBccDd
e) AaBBCCdd

i really dont understand the question at all. I'm sure that if someone can show work for one of them, i'll be able to figure out the rest. Please, this is due tomorrow, I've been working on this for a week, and I've already done 30 of them. :(

Using the chart below, write the amino acid sequence coded by for by each mRNA strand. (Note: This code is based on the mRNA codons, not the tRNA anticodons. The source for the chart is: http://www.bioscience.org/atlases/genecode/genecode.htm) It might help if you write down your answers from the mRNA question so it is easier to complete. Otherwise, you'll probably have to move up and down the screen.

Can anyone help me with this biology question? It reads,

In human cells, 2N=46. How many chromosomes would you expect to find in a sperm cell? a egg cell? a white blood cell? Explain.

I really need help and if you could explain it to me I would really appreciate it.
