“A demonstrative and convincing proof that an acid does consist of pointed parts is, that not only all acid salts do Crystallize into edges, but all Dissolutions of different things, caused by acid liquors, do assume this figure in their Crystallization; these Crystalls consist of points differing both in length and bigness from one another, and this diversity must be attributed to the keener or blunter edges of the different sorts of acids.”
Nicolas Lemery“The researchers looked deeper into these observations, in hopes of gaining insight into the mechanisms underlying the high evolutionary rate and extraordinary immunologic plasticity of influenza HA. They probed in more detail the precise codons that are used by the virus to encode the influenza HA1 protein. The discriminated between codons on the basis of volatility. Each three-nucleotide codon is related by a single nucleotide change to nine 'mutational neighbours.' Of those nine mutations, some proportion change the codon to a synonymous codon and some change it to a nonsynonymous one, which directs the incorporation of a different amino acid into the protein. More volatile codons are those for which a larger proportion of those nine mutational neighbours encode an amino acid change. The use of particular codons in a gene at a frequency that is disproportionate to their random selection for encoding a chosen amino acid is termed codon bias. Such bias is common and is influenced by many factors, but here the collaborators found strong evidence for codon bias that was particular for and restricted to the amino acids making up the HA1 epitopes. Remarkably, they observed that influenza employs a disproportionate number of volatile codons in its epitope-coding sequences. There was a bias for the use of codons that had the fewest synonymous mutational neighbours. In other words, influenza HA1 appears to have optimized the speed with which it can change amino acids in its epitopes. Amino acid changes can arise from fewer mutational events. The antibody combining regions are optimized to use codons that have a greater likelihood to undergo nonsynonymous single nucleotide substitutions : they are optimized for rapid evolution.”
Michael G Cordingley, Viruses: Agents of Evolutionary Invention“Stolen oranges also have Vitamin C. Likewise, a stolen salmon, too, has omega-3 fatty acids.”
Mokokoma Mokhonoana“Self-pity, while it should be accorded due respect, is the greatest of all acids to the human soul.”
Paul Hoffman, The Last Four Things“Save your skin from the corrosive acids from the mouths of toxic people. Someone who just helped you to speak evil about another person can later help another person to speak evil about you.”
Israelmore Ayivor“Its snaky acids kiss.It petrifies the will. These are the isolate, slow faults That kill, that kill, that kill.”
Sylvia Plath, Ariel“The only religious opinion I feel sure of is this: self-awareness is not just a bunch of amino acids bumping together.”
Robert A. Heinlein, Stranger in a Strange Land“Don’t let the acids of bitterness eat away inside. Learn the secret of trusting Christ in every circumstance.”
Billy Graham, Billy Graham in Quotes“If the results of the present study on the chemical nature of the transforming principle are confirmed, then nucleic acids must be regarded as possessing biological specificity the chemical basis of which is as yet undetermined.”
Oswald Theodore Avery“Valkyrie stood there and waited for her to start making sense."There is a vegetable-plant hybrid we've been working on, modifying the genes and receptors, mutating the proteins and acids so that they are, in effect, neurotransmitters. Our work on the synapses alone has been quite illuminating."Valkyrie stood there and waited for her to start making sense.”
