And milk contains a whole load of hormones that are not too healthy for you.

A female has two X chromosomes, a male only one. If the disease is X-linked, the male won't have a healthy copy of the allele to rescue its phenotype; a female will be heterozygous, so there can be rescue of function. A Y-linked disease will always be passed on from father to son.

If they were born cross-eyed, they will experience their eye-sight as normal: the only problem they might have is experiencing difficulty in estimating distances.

There are other forums on the internet that have 'homework question' forums only :wink: the key is directing students to the right answer, like suggesting to look up the article by Watson and Crick on http://www.pubmed.com and look up the book on http://www.amazon.com.

I voted flexibility, experiments don't always work out as planned. As a scientist you need to know how to bounce back and change your setup or hypothesis.

Ribosomes are syntesized in the nucleus, the structure at which this occurs is the nucleolus. When the ribosomes are produced, they move out of the nucleus to the rough endoplasmatic reticulum. More information here http://cellbio.utmb.edu/cellbio/nucleus3.htm

Virusses are MUCH smaller than bacteria. I don't know how they stain virusses, but you could use labeled antibodies.

The average molecular weight of the four nucleotides is 330 daltons, you can use this average.

The individual molecular weights are:
A 313.15
C 289.13
G 329.19
T 304.19

There could be a mutation (in that individual) at the site the primer is supposed to bind, this way one allele might not amplify.

You did the right thing to pblast it, since it is highly conserved across phyla it means that the function of the protein is important. You are right to assume that the function of the protein will be the same as the others (if the homology is high). Did you find a protein that gave an exact match? ...

Either it is a problem in the way the electricity is flowing through your gel, or it is a problem of how the gel polymerizes. I personally think 100V is a lot, I run 7% polyacrylamide gels at 60V; I only use a high voltage to get the samples into the gel, after which I turn it down.
