| rank-difference correlation | The relationship between paired series of measurements, each ranked according to magnitude, which yields a coefficient known as rho; the value of rho varies from zero (no relationship) to +1.00 (perfect relationship). (05 Mar 2000) |

| correlation | <statistics> most generally, the degree to which one phenomenon or random variable is associated with or can be predicted from another. In statistics, correlation usually refers to the degree to which a linear predictive relationship exists between random variables, as measured by a correlation coefficient. Correlation may be positive, i.e., both variables increase or decrease together or negative or inverse, i.e., one variable increases when the other decreases. (18 Nov 1997) |
| correlation coefficient | A measure of association that indicates the degree to which two variables have a linear relationship; this coefficient, represented by the letter r, can vary between +1 and -1; when r = +1, there is a perfect positive linear relationship in which one variable relates directly with the other; when r = -1, there is a perfect negative linear relationship between the variables. (05 Mar 2000) |
| product-moment correlation | A statistical procedure which yields the correlation coefficient referred to as r (-1.00 to +1.00) and involves the actual values, rather than the ranks (rank order) of the measurements. (05 Mar 2000) |
| codon, nonsense | A codon that is not assigned to an amino acid or to any stop signal. It was originally thought that nonsense codons were synonymous with terminator codons (codon, terminator) in that they signaled termination of a protein chain. Recent studies have found this not to be true. (12 Dec 1998) |
| nonsense | As used in genetics, relating to a mutation that causes a sequence such that the growing peptide chain terminates, often after several incorrect amino acid residues are incorporated. (05 Mar 2000) |
| nonsense codon | <molecular biology> The three codons, UAA (known as ochre), UAG (amber) and UGA (opal), that do not code for an amino acid but act as signals for the termination of protein synthesis. Any mutation that causes a base change which produces a nonsense codon results in premature termination of protein synthesis and probably a nonfunctional or nonsense protein. (13 Nov 1997) |
| nonsense mutation | <molecular biology> A mutation that causes a polypeptide chain to be ended prematurely. (13 Nov 1997) |
| nonsense strand | <molecular biology> DNA that does not code for part of a polypeptide chain or RNA.This includes introns and pseudo genes. In eukaryotes the majority of the DNA is noncoding. Noncoding strand refers to the so called nonsense strand, as opposed to the sense strand which is actually translated into mRNA. (18 Nov 1997) |
| nonsense suppression | Mutant tRNAs that read a chain termination codon as the signal for incorporation of a specific amino acid residue. (05 Mar 2000) |
| nonsense syndrome | <syndrome> A psychotic-like condition, without the symptoms and signs of a traditional psychosis, occurring typically in prisoners who feign insanity; e.g., such a person, when asked to multiply 6 by 4, will give 23 as the answer, or he will call a key a lock. See: malingering, factitious disorder. Synonym: nonsense syndrome, syndrome of approximate relevant answers, syndrome of deviously relevant answers. (05 Mar 2000) |
| nonsense triplet | A trinucleotide (codon) in which a base change to a termination codon results in premature termination of the growing polypeptide chain and, consequently, incomplete protein molecules, a termination codon. (05 Mar 2000) |
