The point is to make money before too much resistance develops. The development of resistance, though, can be slowed by planting non-GM varieties nearby that act as refuges for the non-resistant bugs. These bugs then breed with those who can eat the GM varieties, thereby keeping the resistance allel...

In molecular phylogenetics, the more closely related the groups you want to differentiate are to each other, the more variable the loci you use need to be. So, for closely related groups such as populations of a single species, you need to use loci that are variable enough to possess differences bet...

Just came across this reference while looking for something else. Maybe it could help.

Perhaps I should just leave well enough alone, since I think the discussion up to this point at least clarifies the original poster's concern, but I've been ruminating about Canalon's comments. At first I agreed, but then I kept coming across situations in the literature that led me to doubt that th...

Hi Canalon,

Yes, I see your point. ALL antisense strands will have an identical sense counterpart. This certainly makes things easier. So, 65536 it is.

4X4X4X4X4X4X4X4=65536 for a single strand, as in a primer. Twice this number if you include the complementary antisense strand (each strand being a different molecule), but I suppose some of the complementary strands would be the same as some of the sense strands, so the actual number of different m...

short answer, no .. a bit more, "Ribozymes" are RNA molecules that have enzymatic activity. How common these are "in the wild", I don't know. Most (all?) "coenzymes" are nonprotein cofactors that are necessary for the enzymatic activity of the proteinaceous enzymes that...

SNP research will only grow. Now that the HAPMAP project has laid the groundwork, and with Affymetrix producing 500K SNP chips, human medical research will use these tools for many case/control studies. Not many causative SNPs are known, but as markers, SNPs will be huge tools for QTL and other mapp...

Hi,

I don't think it's a downloadable programme, but you can go to http://weblogo.berkeley.edu/logo.cgi and input alignment files. Since it's web-based, it should be accessible to Macs.
