May I not focus on emotion, I rather consider it a form of neurological result, but other neurological effects like sensation, memory,etc shall have equal ranking. Now you are talking about inputs, of many forms, but ultimately translated into nerve impulses, bringing about various neurological effects. I shall say in scientific sense, energy is used in the transfer process, nerve impulses are energy-demanding. But I am open to other intepretation that 'energy' may refer to other things in metaphysical or philosophical senses. Then, when you consider if emotion, or other neurological effects a

I heard from a lecture of major occurrance of Down's syndrome in female, but when I check for verification I found male to female ratio at 1.3 to 1. So maybe something wrong there, but this leads me to think about why one sex will be more susceptible to some genetic disease like chromosome 18 trisomy. Any suggestion?

To have what you said done, the piece of foreign DNA should be integrated into genome (how to get in cell? how to be integrated?), the chances are very low especially without homologous sequence for homologous recombination; even if it comes in, it will mostly be a mosaic instead of a genuine organism with all genomes identical.

This is actually I encounter when I am doing an exercise. Now there are 2 phage mutant but we don't know if they occur at the same locus. The usual practice is to conduct a complementation test (to cross them in a restrictive host and see if lysis occurs). But, because it is provided that this phage is T even and replicate with headful packaging (genomes concate and every capsid accomodates 1 genome plus some more bits), my question is why can't we use a permissive host to do the job. Let say if the two mutations occurs at the same locus, in a permissive host no matter how they perform recombi

In yeast two hybrid (Y2H) system, binding domain (BD) and activation domain (AD) of GAL4 protein are separated and linked to heterologous protein. Besides the protein structure of BD-AD, I have also heard of BD-repressor domain structure. The problem is I don't know of any example, could anyone suggest some?

Try to fit the slope into your equation.

your prof should be referring to the amount of genetic material instead of chromosomes.

It depends on what type of infectant you are concerning about.

That means you got the insert but you cannot sequence it because it gave you just a 600bp piece? Then you may use another primer to continue the work, better to have some regions in overlap with the first 600bp, then you will get your first 600bp, and a second piece of another 600bp with some overlap so as to enable arrangement of fragments.

Well, the protein consumption should be approximate to the body composition, that if 25% of the body is made up of protein, just take the approximate amount of your total calory intake, in this way the protein could be better utilized to prevent excess or deficiency, after all they are broken down and assimilated eventually. Whether or not excess protein gives fat depends on the amino acid, but on average a protein molecule should contain most of the twenty amino acids in the body so usually it is true that excess protein could put more fat. But I don't think it is significant if you compare t

Because the chance to select a driver on bus A is different from the chance to select a student in bus A, so two expected values should be different.

So if it appears purple, should it absorb much of the purple light? Apply this question to its complement color and you get the answer. I think you may not provide a definite wavelength but a range.

Think of circumstances when you want to mount a bacteria dead or alive.

I don't think you can find mp or bp of other ions like the common ones, Na+ and K+. You should be looking for compounds.
