The Real ME: A Stock Photography Resource for the Media
We’ve all seen them in the news stories about ME/CFS: the guy in a suit at the office, yawning; the beautiful woman sitting at her desk with her immaculate make-up and elegantly coiffed hair, hand to her head and looking slightly pained.

How consecutive SNPs result in proteins

    First the DNA (A,C,G,T) is transcribed into RNA (A,C,G,U). Then the RNA is translated into amino acids (cysteine, glutamate, glycine, tryptophan, serine, etc). And these amino acids then become proteins.

    While the RNA is being translated, it's partitioned into sets of 3 consecutive SNPs, such as "AGG", which are called codons. Each codon results in a specific amino acid being created. "AGG", for example, would result in Arginine. Multiple codons can create the same amino acid. In addition to arginine being created from AGG, it can also be created from AGA, CGU, CGC, CGA, and CGG.

    Here's a very nice diagram from illustrating which amino acids are created from which codons:

    Anyhow, there's some more complicated aspects, but I thought this was interesting and wanted to have it somewhere that I can find it again :p
    Critterina and ukxmrv like this.
