I'm not aware of any general database for this. It's simply too large a subject for a generalized database to be useful. The way most people, I believe, determine this information is in looking at a specific target or looking at a specific small molecule. For example, for drugs, pretty much any seri...
Depends on your definition of bringing a dead person back to life. After 8 minutes of death (unless lowered temperatures are involved), the damage to the brain is simply irreversible. You might want to look into Apoptosis vs Necrosis. One might be able to reverse the apoptosis cycle in a cell, but n...

I'm trying to find a good source for information about the anatomy and physiology of the drosophila brain. Specifically, what I'm looking for is something that maps out the types of neurons in the various regions of the drosophila brain, their interconnections, and the specifics of channel types, re...

I have a question regarding DNA replication... As I understnad it, you have a coding strand and a template strand. The template strand (or is it the coding strand?) is copied to make mRNA (so the mRNA should look like the coding strand with the Us instead of Ts). Now, my question is, how exactly doe...
The purpose of cellular respiration is to generate energy in the form of certain molecules (ATP being the major one). There are actually several processes for creating energy in cells. Oxidative Phosphorylation, the Citric Acid Cycle, and Glycolysis are the three big ones. Wikipedia has entries on a...
A small correction, though I guess a bit late for the question: Technically, allolactose is the inducer. e. coli converts a small amount of lactose to allolactose and this then binds to the repressor.
Nite is correct. Technically immunization is to be made immune and this can happen by natural methods. If you get chicken pox, you are then immune to them in the future. So you are immunized against chicken pox. The confusion is probably caused by the fact that people sometimes call vaccinations, im...

Well, the RNA start codon is AUG. There is no ATG in RNA because uracil is used instead of thymine. It depends on how you look at it, though: In DNA you're going to have two strands: ATG on one side and TAC on the other for the start codon. So I guess it depends on which side you're looking at it fr...

Okay, got a somewhat advanced question here... I'm just starting with immunology and I'm curious about an aspect of T-Cell activation. As I understand it, naive t-cells are activated (generally in lymph nodes) by antigens brought by APCs (antigen presentation cells). When the t-cells are activated, ...
