An excerpt of my required reading/comprehension since January:

"During translation, the sequence of codons along an mRNA moecule is decoded, or translated, into a sequence of amino acids making up a polypeptide chain. The codons are read by the translation machinery in the 5'--3' direction along the mRNA. Each codon (triplet code) specifies which one of the 20 amino acids will be incorporated at the corresponding position alon a polypeptide. Because codons are base triplets, the number of nucleotides making up a genetic message must be three times the number of amino acids making up the protein product. For example, it takes 300 nuceotides along and mRNA strand to code for a polypeoptide that is 100 amino acids long."

I sit and stare at my blog page --and the synapses do not fire. They are all used up.
