CC the copy cat and genomic imprinting

I read that the first pet to be cloned(cat) is completely healthy and has none of the problems that other cloned mammals have. How is it that the cat doesnt even show signs of paternal/maternal disomia due to genomic imprinting?

Depending on how exact your teacher is it may not be correct to say that the enzyme binds a substrate, but that it binds the substrate in distorted conformation that resembles the transition state of the reaction that is being catalyzed.

Re:

What Dave meant was that if there are many people requesting a particular category then we start considering it. Until now, you are the only person asking for a developmental biology section. I'm not saying developmental biology is not important, but most likely there wouldn't be many posts there. ...

Developmental Biology Forum

I would like to suggest a forum devoted to developmental biology, its such a vast and complex subject I think its merits its own forum.

DNA repair after replication always happens, but if the cell delays the S phase due to DNA damage it will repair it first, then continue. Look for p53, it is a major element in this 'delay or die' decision.

.... except His, you need to know that histidine has a pKa near neutrality.

Re: 20 Amino Acids

Thank you for the info on selenocystein, thats awesome.

And yes, you need to know the names and structures of all the AA, the Pka values are not so important because in the proteins they also depend on the microambiente of that residue.

Re: Question on Turners syndrome

Think of it this way: The phenotype "Being a dude" is Y-linked dominant, so what would somebody with the genotype X0 be?

From what I read he basically saud that anybody who has worked with black people knows that they arent as well adapted to a working environment. I personally dont have any experience with this, but Ive heard the same thing on many independent accounts.
