Not a textbook but it helped me a lot to understand microbiology:
The other end of the microscope from Elmer W Koneman.

It gives a lot of detailed information (composition of the cell wall etc) in a story-context and is really easy to read and understand. And much more fun than textbooks :)

Hi,
what is 20 cycles later? In my qPCR everything after cycle 40-ish was just noise. Can you see a band on a gel after a standard PCR?

Re: how to cultrue IEC-6

Hi, Sigma-Aldrich says: DMEM + 2mM Glutamine + 0.1 IU/ml Insulin + 5% Foetal Bovine Serum (FBS); 5% CO2 Different people use different protocols for different experiments. Sometimes they grow fine in either, but change slightly which makes one version more suitable for your experiments. If you don't...

Hi, I hope it's not too late for a reply. If you didn't collect more ants so far, I wouldn't try it anymore. Most likely the colony smell is gone by now and it can be quite hard to get "strangers" accepted into a colony. If there are still pupae around, you could give those to the colony -...

Topic: A question about pubic hairs.

I guess the same way every other hair does it. After a while (depends on sex, individual and location) the follicle shrinks and the blood supply is stopped. This leads to loosing the hair. But it has nothing to do with cutting or shaving hairs, only with the time that has passed since the hair start...

Yes, it is possible that there are more than two different alleles for a gene. The most popular example, that comes into my mind, is blood types (AB0-system). But it is not possible that more than one is recessive to all the others - what would happen if two different recessive genes are inherited? ...

Ok, I apologize if I confused the enquirer.
I always thought that if I have a line straight through (without bends) that means that it is still the same species as it was when it split. But apparently I got that wrong.

As far as I know, they are not. In B and D there is one splitting between species 1 and 3 and 2 arised out of 3, which leads to 2 being closer related to 3 than to 1. This isn't the case for C. Here there is one splitting between 1 and 2 and 3 arised out of 2. This means that 3 is closer related to ...

Hi, evolution is not about going uphill, onwards or whatever. It's only about what's best at the moment. So if an environment changes so that only specifically spezialized organisms have a lot of off springs the population will be uniform after a while. But most of the time it's different things tha...

You know the volume per heart beat and the number of them in 7 minutes.
And you want to know how much volume passed the heart in 1 minute.

That's simple cross-multiplication (or logic). How did you get to 1.43?
