Re: Depolarization = ion channel opening?

I think you are correct (or more precisely when the Na+ channels open since the K+ open later). There is a threshold voltage that switches the state of what I found to be a flip-flop. The circuit is also called a "monostable multivibrator".

Re: Codons are triplets, but what's a Singlet, Doublet, etc?

I finally have something for you! To make it as easy as possible for us to see all the variables and how they are formed I wrote a minimal code subroutine to save on disk (and in RAM) a list of 1 to 8 letter codons in Base4 or Base5. The lines of code to save to disk can later be removed, for use in...

I did not try it yet, but UCSC Genome Bioinformatics has a "Custom Tracks" feature that would seem to be able to align what you need, by accession number:

Does that work for you?

Re: Codons are triplets, but what's a Singlet, Doublet, etc?

Ah ha! Thinking it terms of words/letters sent Google Scholar straight for something in a 1982 paper that I did not know about, where in its Abstract it theorizes a two letter codon: THE POSSIBLE ROLE OF ASSIGNMENT CATALYSTS IN THE ORIGIN OF THE GENETIC CODE VAHE BEDIAN * Department of Biophysical S...

Re: Codons are triplets, but what's a Singlet, Doublet, etc?

Thanks for the excellent keywords (BLAST algorithm) that worked great for finding ideas in the google search engine. I am familiar with the NCBI’s BLAST search engine and interface to their supercomputers, but until now the program has been more precisely looking for abundances (as opposed to simila...

Codons are triplets, but what's a Singlet, Doublet, etc?

I'm working on a minimal-code program (a simple how-to for programmers and general public) that compares/displays chromosomes, using a technique I called "digital banding". Here is the illustration for Orangutan, Gorilla, Chimp, Human Chromosome 2. m And one with what I called "Bright...

Re: function of a centriole?

Here's an excellent resource on the possible role of centrioles in cellular intelligence: m From what I know about the topic, a cell can divide without centrioles but cannot develop into an animal due to loss of migration behavior that makes their cells so much more "alive" in comparison t...

Here's something that I put together and the truth surprised even me, and I'm used to science always being surprising! ------------------------------------------------- There is a common biological mechanism present even in the simplest of multicellular organisms like Volvox and C.Elegans where the ...

Re: Why The Religious Minded Rule Science With Science

Hi MjolnirPants who in feedback elsewhere said I am an "Enormous anus"! If that is true then you must be very careful what you feed me. Never know what will come splattering out the other end. Hehehe... It's great to see you admit to having a religious side too. But you don't have to tortu...

Re: Question About Common Descent

Could someone inform me about the status of common descent at the molecular level? In particular I would like to know if, from the study of biochemistry and evolution, it has been established that the various primative molecular life forms developed from a single sequence of chemical activities at ...

Re: Natural selection is proven wrong
