| repetitive DNA | <molecular biology> Nucleotide sequences in DNA that are present in the genome as numerous copies. Originally identified by the C0t_ value derived from kinetic studies of DNA renaturation. These sequences are not thought to code for polypeptides. One class of repetitive DNA, termed highly repetitive DNA, is found as short sequences, 5-100 nucleotides, repeated thousands of times in a single long stretch. It typically comprises 3-10% of the genomic DNA and is predominantly satellite DNA. Another class, which comprises 25-40% of the DNA and termed moderately repetitive DNA, usually consists of sequences about 150 to 300 nucleotides in length dispersed evenly throughout the genome and includes Alu sequences and transposons. (18 Nov 1997) |
| repetitive sequences, nucleic acid | Nucleotide sequences present in multiple copies in the genome. They include direct, inverted, tandem, and terminal repeat sequences and the alu family repeat (named for the restriction endonuclease cleavage enzyme alu I). (12 Dec 1998) |
| highly repetitive DNA | <molecular biology> The fraction of the eukaryotic genome which consists of a short sequence of nucleotides that is repeated thousands of times all over the genome. Highly repetitive DNA is very similar to satellite DNA. (09 Oct 1997) |
| DNA, repetitive | DNA sequences that are repeated in the genome. (12 Dec 1998) |
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
| pre-excitation, mahaim-type | A form of pre-excitation characterised by a normal pr interval and a long qrs interval with a delta wave. (12 Dec 1998) |
| pre-excitation syndromes | Conditions characterised by activation of the whole or some part of the ventricle by the atrial impulse earlier than would be expected if the impulse reached the ventricle by way of the normal specific conduction system only. (12 Dec 1998) |
| excitation | <physics, psychology> An act of irritation or stimulation or of responding to a stimulus, the addition of energy, as the excitation of a molecule by absorption of photons. Origin: L. Excitatio, citare = to call (18 Nov 1997) |
| excitation contraction coupling | <physiology> Name given to the chain of processes coupling excitation of a muscle by the arrival of a nervous impulse at the motor end plate to the contraction of the filaments of the sarcomere. The crucial link is the release of calcium from the sarcoplasmic reticulum and the analogy is often drawn between this and stimulus secretion coupling, that also involves calcium release into the cytoplasm. (18 Nov 1997) |
| excitation radiation | <radiobiology> Line radiation (at characteristic frequencies / wavelengths) as a result of the promotion of electrons or other constituent particles of a larger system to excited states, and the subsequent de-excitation of these states by radiative transitions. (09 Oct 1997) |
| excitation spectrum | Fluorescence produced over a range of wavelengths of the exciting light. (05 Mar 2000) |
| excitation wave | A wave of altered electrical conditions that is propagated along a muscle fibre preparatory to its contraction. (05 Mar 2000) |
| law of excitation | A motor nerve responds, not to the absolute value, but to the alteration of value from moment to moment, of the electric current; i.e., rate of change of intensity of the current is a factor in determining its effectiveness. Synonym: Du Bois-Reymond's law. (05 Mar 2000) |
| law of polar excitation | A given segment of a nerve is irritated by the development of catelectrotonus and the disappearance of anelectrotonus, but the reverse does not hold; i.e., excitation occurs at the cathode when the circuit is closed and at the anode when it is opened. Synonym: Pfluger's law. (05 Mar 2000) |
