Simple DNA question

Is the double-helix considered to be two molecules of DNA or one molecule? Basically, is each strand a separate polymer of DNA, or is it looked at as one polymer together.

If it's one polymer together, what happens in interphase when the double-helix is separated in order to replicate?

Not sure, but I think number two should be false. My understanding is that after the first division in meiosis, the sister chromatids are still jioned, and therefore still considered one chromosome.

Epistasis vs Polygenic Inheritance

Could anyone please briefly explain the difference between epistasis and polygenic inheritance? My biology book makes these two seem fairly close to one another, as multiple genes affect the same phenotype. The only difference I can really tell between the two is that polygenic inheritance seems to ...

Removing a turtle's shell

Is it possible to remove a turtle's shell without killing it?

Note: I'm not planning on doing this, just something me and my friend were discussing.

NaCl dissolved in water

In biology we learned that molecules often do not share the same properties of the individual elements they are composed of. We also learned that when table salt is dissolved in water, it breaks apart into Na and Cl atoms. Why is it, then, that when salt is dissolved in water that it still tastes sa...

Definition of a solution

In my introductory biology class, we are learning about how water creates aqueous solutions. I am not sure about the definition of a solution, however. Does a solution mean that each individual molecule of a solute is separated from every other molecule, or that each individual element from the solu...
