Biology - February 2007

My person's record contains a list of base sequences for genes F, H, A, and G. But my teacher told our class to only copy down the generations and not the base sequences. So the generations are:

F1
F1
H1
H2
A1
A1
G2
G2

..So I'm having trouble answering the questions:

1. Notice that your person's record contains a list of base sequences for genes F, H, A, and G. Why does this record show two sequences for most or all of these genes?

2. The sequences shown are only 30 bases long. Do you think that each sequence represents one complete gene or only a portion of a gene? Explain your answer.

3. What explanation can you offer for the observation that males have only one F gene and never two?

4. Consider genes H, A, and G. For which of these genes are you homozygous? For which are you heterozygous? List two ways in which you can determine this from the information on the screen.

Limestone, an underlying material for many soils, dissolves and corrodes when exposed to high concentrations of hydrogen ions. How is this information important in understanding the effects of acid precipitation?

An enzyme can only catalyze a reaction b/w very specific reactants due to their shapes. what might happen if the enzyme's shape was changed? Pls include at least one way to change the shape of an enzyme.

I'll give the best answer to the person who can answer well and it makes sense or not. Thanks!

In biology we are studying fermentation. We had to make bread with yeast (because it contains alcoholic fermentation) I made biscuits. We have to write a paper on how fermentation is involved in the bread making process. HELP!?!? THANKS!

I have a project for biology. We have to create a cell model. It can either be an animal cell or a plant cell.

But for extra-credit, we can create a specific kind of cell like these:
-nerve cell
-intestinal lining cell
-muscle cell
-etc....

So my question is, What is the best and easiest cell to make?

UH..
so far.. all i know is
DNA-- A=T C=G
RNA-- A=U C=G

So if like.. the mRNA codon was UGG the DNA would be... ACC?
then what would be the anticodon? what the heck? i don't get this.
