The Discovery Institute Is Just Plaid Wrong..

They released a statement today that is just absurd regarding PBS airing too much evolution-related material..

Here's my analysis: http://thebioblog.com/2009/12/discovery ... darwinism/

Why are there not more education people out there stopping people like this?

There are other considerations that need to be made.. For X-chromosome alleles in humans and most other diploids, only one allele is generally necessary for expression; only one X-chromosome is active, the other becomes a barr body . Both alleles are generally important for diversity of protein expr...

Look up the associated proteins of Cyclin A, B, C, D and E, as well as the cyclin-dependent kinases for those proteins (CDK-A, etc..).,

For the second one, you should look at the associated proteins of the MTOC and centriole.

Chroma, you are correct in your statement regarding eukaryotes forming from a combination of bacteria and a primitive archaea, along with some scattered symbiotic events and horizontal gene transfers. At least that's what PostDocs from the Center for Evolutionary Functional Genomics discussed in my ...

I don't believe there is enough information to determine whether one is paternal or maternal, as kolean described. Based upon the image, the answer would be L, the second stage of meiosis. The first division of meiosis would divide a tetrad into a diad.. you would see a traditional "><" ch...

Energy Usage of Neurons

Apparently neurons are using far less energy than expected.. even though they consume 20% of our consumed energy? (More)

Mitochondrial Gene Replacement

Researchers have figured out a potential way to prevent mitochondrial DNA related diseases by trading out healthy mitochondria for the mutated mitochondria. Apparently there are no side effects.

All genes are necessary and required.. that's the general rule of genomics. It's mutations in genes that affect the "good" or "bad" effects of the gene in particular. Considering the pathway the p21 gene is in, a mutation in it would be a negative thing.

Where your thermal cycle times the same as theirs? What about the voltage across the gel and the time of the run?

Did you expose the RNA to light too much? It's possible you denatured them. Also, there may have been RNAses in your extract that could have reduced copy count drastically.

If you're taking a "course" for credit.. you'll generally need to be enrolled in whatever institution is offering the course. Where are you trying to transfer credit to? I would suggest speaking to an academic adviser there..
