Heredity B/Designer Genes C

[Cedavis6]

Does anyone have a Division B test?

Have you checked the Test Exchange?

Also, did anyone else notice that DNA sequencing is listed twice on possible question topics?

Yeah. I think all of them are Div. C, but I've taken all of them, anyways. So I guess new Div. C tests would work too, it's just that then I get confused about what I need to know and what I don't.

If I only have time to study a couple topics in depth, which ones do you think I should study? (for division c)

At rida: No. You are only allowed what you can fit on the page itself.

To answer PicturePerfect (at least on some cases):
1. At the B division level, the rules do not mention DNA fingerprints. They may be mentioned, but I wouldn't devote a tremendous amount of time to studying them.
2. For the Hardy-Weinerg problem, was there more information given? I'm not sure how one would solve this one with only this information. However, at the B-division level, there is no requirement for it on the rules.
3. I might know the differences (at the most basic level) between them (uses, basically) just in case they show up in like a vocab section or something, but I wouldn't be too concerned about them. They aren't in the rules.
4. The number of possibilities for each trait multiplied together. Like this would be 2x2x2x2x2=32.
5. That might be a rounding issue- I can't be sure without seeing it. And this is none, because the kidney shape is a form of incomplete dominance between the round and slit shape. The males only have one X chromosome, so they can't be heterozygous, and thus can't have the blended form.
6. I would assume that the C allows production of pigment, and without it, there cannot be production of the pigment. I'd make a punnet square, CcIi x CcIi. Then, because you must be ii with a C to be colored, just cross them out and count the remainder. I got 13/16 being white.

~Hope this helped! Feel free to ask me anything, this is like my absolute favorite.

2: there is enough information using the Hardy Weinburg equilibrium equation and 1-q=p and vice versa
5: Not a rounding error. Frequency A allele equals 1/2[Frequency Aa] (I think)
But don't worry about it for Division B.

I'm willing to do a test trade if you have one yourself, but I won't put it on the test exchange for everyone. Let me know if interested. I'm going to do one with someone else on the board whenever I find time...

Oh well.. I don't have one

Is Protein Synthesis the same thing as Gene Expression? If not, could someone please explain? It seems to me that the steps are the same...

[asquaredplusb]

Yes - Protein Synthesis and Gene Expression are terms that can be used essentially interchangebly.

[Half-Blood-Princess]

Well I always thought Gene Expression was: DNA to RNA to Protein, and Protein Synthesis was just: RNA to Protein.

Hello,

Essentially, you are correct. However, Gene expression is a more general term than translation. In certain cases, functional RNA products can be the result of gene expression (such as tRNA), so the term is not limited to proteins. Gene expression also includes DNA regulation, splicing, and post-transcriptional RNA modification. In short, it refers to the control and transition of a given genotype to a certain phenotype.
