Could what restart in the wrong spot? I think you mean polymerase, but could you clarify?

We should know to trust God to provide for our needs and not be foolish with the resources He has given us.
Please keep God out of the science forums, there's sperate section for that. Why was it necessary to say that? What is the point of the post?

How will you measure which neurons are being fired? Are you doing this research at university/hospital with PET scan capabilities? Will you use the radioactive tracers?

Didn't Kenedy promise we'd switch to metric by 1969? What happened?

Maybe it would be better to start a new thread with that rule applied. That way people will have to see the rule before the post.

I've never heard any evidence towards this. The lagging strand (the discontinued replicated strand, made by okazaki fragments) will replicate slower then the leading strand. I would think nucleases and polymerases identify and correct most mistakes.

No, just go to http://www.geocities.com create a free username if you don't already have a yahoo passport. Then upload the file onto your file manager. Then post the link on the forum.

Where are you doing this research. Are you planning on entering competitions? Are you allwed to injeect things in peoples brains?

I'm in the same situation as you, although a little more decided. I suggest you use http://www.collegeboard.com to help you look for colleges and universities. (althgouh now that I think of it, that might be for American universities.) Good luck, whatever you decide to do.

I've always believed we use the term imaginary as a way to force impossible numbers (such as the sqaure root of -1) to fit into our number system.

For an object going that fast, it would need a large deceleration time. Maybe if the flight went past it's target and was able to turn around in flight while decelerating. I don't know too much about this. Does that make any sense?

My friend had an idea. A sword that contained, at it's tip, atoms with opposite charges. Somehow blowing all positivly charged and negative charged atoms apart.

applied force - net force = resistive force.
Thanks, that's the equation I was missing. I couldn't get from applied force to Force of Friction (the only resistive force being considered).
Thanks for your help guys.

Could anyone help me with this problem?
a force of 40.0N accelerates a 5.0kg block at 6.0m/s^2 along a horizontal surface. How large is the frictional force? What is the coefficient of friction?
I can't figure out how to get the force of friction without given the proportionality constant.

That's brilliant!

Try hosting it on geocities, so we all can get a copy.

Do tektites affect the way light is absorbed/reflected?

Technically you're right, but it's my fault I should have made the picture clearer. By the question mark, I meant you didn't know the phenotype or genotype of the mother. I'm sorry, that doesn't make to much sense. How could you see the phenotype of one and not the other? I just creating a hypothetical situation. I should have been more specific. Sorry

That's a good idea

Jeez, so much debate over one simple comment. I didn't even mean anything important.

maybe he wrote the script?

That, that sounds like what it was. Just some fancy computer animations for the general public. I do believe it was offered as a possible evolutionary pathway, and not the only one.

Dominant and recessive traits are not black and white. You have to keep in mind that a heterozygous dominant male can mate with homozygous recesive female. You won't know that the male is heterozygous until they have children. If any children express the recessive trait, then the male has to be heterozygous.
In this picture a homozygous dominant male mates with homozygous recessive female. All there children are phenotypically dominant, although they are actually heterozygous dominant.
In this picture a phenotypically dominant male mate with a recessive female. Becasue it expresses the dominant trait, there is no way to tell whether it is heterozygous or homozygous until it's children are born. Once you get a phenotypically recesive offspring, then the father has to be heterozygous, in order for it's children to recieve two recessive alleles.
When creating a pedigree, its important to know what the children are in order to discover the genotype of the parent.
In this picture the genotype of the mother is not known. But because on of the children is recessive (not shaded) and the father is phenotypically dominant, we know that the mother is hommozygous recesive, and the father is heterozygous dominant.
The punent square would look like this:
Or, both parents could be heterozygous Dominant, creating an offspring with recessive traits.
The only way to know which situation is true, is to mate the recessive offspring and see what phenotypes occur in it's children.
Creating a pedigree can be challenging, but interesting. Keep in mind, however that this form of punnet sqaure can only be used with looking at simple genes. Most phenotypes, in humans especially, are controlled by many genes. Its hard to create a genotype for a trait that is controlled by many different factors. Often times a dominant gene won't be expressed because of another gene controlling it.
Hope I helped!

It all comes back to respiration, and the creation of ATP from a proton gradient. Muscles use the actin-myosin to expand/contract. I assume cilia etc., use a similar system.

I like the subjectivism in English. It makes a nice change from silence. There's no definitive answer. There's no one intepretation. Every opinion is valid as long as you can back it up with fact. I enjoy using both styles of thinking
