degeneracy

(dĭ-jĕn′ər-ə-sē)
n. pl. degenera·cies
1.
a. The process of degenerating.
b. The state of being degenerate.
2. Genetics The presence in the genetic code of multiple codons for the same amino acid. Also called redundancy.
Genetics Hereditary degeneration
Molecular biology The presence of 2 or more ‘synonym’ codons for a single amino acid, i.e., redundancy. See Degenerate code
Psychiatry An obsolete term for ‘moral bankrupcy’, now included under the rubric of psychotic disorders, formerly deviant behaviour, degenerate behaviour

degeneracy

In the genetic code this is a reference to the redundancy of codons arising from the fact that four bases, taken three at a time, offer 64 possibilities, while it is necessary to code for only 20 amino acids and three stop signals. The effect is that in many cases a change in the third base of a codon will not change the amino acid selected.

degeneracy

a situation in the GENETIC CODE where most amino acids are coded by more than one triplet of DNA NUCLEOTIDE bases. For example, ARGININE is coded by CGU, CGC, CGA and CGG CODONS. See also CRICK.

I was so astonished with the sight of these things, that I entertained no notions of any danger to myself from it for a long while: all my apprehensions were buried in the thoughts of such a pitch of inhuman, hellish brutality, and the horror of the degeneracy of human nature, which, though I had heard of it often, yet I never had so near a view of before; in short, I turned away my face from the horrid spectacle; my stomach grew sick, and I was just at the point of fainting, when nature discharged the disorder from my stomach; and having vomited with uncommon violence, I was a little relieved, but could not bear to stay in the place a moment; so I got up the hill again with all the speed I could, and walked on towards my own habitation.

All my terrifying thoughts were past, the horrors of the place were become familiar, and I felt no more uneasiness at the noise and clamours of the prison, than they did who made that noise; in a word, I was become a mere Newgate-bird, as wicked and as outrageous as any of them; nay, I scarce retained the habit and custom of good breeding and manners, which all along till now ran through my conversation; so thorough a degeneracy had possessed me, that I was no more the same thing that I had been, than if I had never been otherwise than what I was now.
