| random amplification of polymorphic DNA | <molecular biology> A term originally invented by polymer chemists to describe a disordered tangle of a linear polymer chain with curved sections. In DNA parlance the random coil refers to the structure that results from melting or other forms of separation of the double helix, i.e. Helix coil transition. (18 Nov 1997) |
| random amplified polymorphic DNA technique | Technique that utilises low-stringency polymerase chain reaction (pcr) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. Rapd technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes. (12 Dec 1998) |
| polymorphic | <biology> Occurring in several or many forms, appearing in different forms at different stages of development. Origin: Gr. Morph = form (18 Nov 1997) |
| polymorphic epithelial mucin | <protein> See episialin. (18 Nov 1997) |
| polymorphic genetic markers | Inherited characteristics that occur within a given population as two or more traits. (05 Mar 2000) |
| polymorphic leaves | Two or more different types of leaves on plants, in wetland plants, polymorphic leaves may develop due to extended flooding. (09 Oct 1997) |
| polymorphic neuron | Occurring in many shapes. See: multipolar cell. (05 Mar 2000) |
| polymorphic reticulosis | A necrotizing lymphoproliferative lesion with a predilection for the upper respiratory tract. Previously called lethal midline granuloma or malignant midline reticulosis. Treatment is irradiation. (05 Mar 2000) |
| polymorphic superficial keratitis | Epithelial degeneration occurring in starvation. (05 Mar 2000) |
| activity | 1. The state of being active, the ability to produce some effect, the extent of some function or action. 2. <chemistry> A thermodynamic quantity that represents the effective concentration of a solute in a nonideal solution, if concentrations are replaced by activities, the equations for equilibrium constants, electrode potentials, osmotic pressure, boiling point elevation, freezing point depression and vapour pressures of volatile solutes are converted from approximations that hold only for dilute solutions to exact equations that hold for all concentrations. The activity is equal to the product of the concentration and the activity coefficient, a dimensionless number measuring deviation from nonideality. Symbol a. The potential or true thermodynamic activity of a substance, as opposed to its molar concentration. 3. <radiobiology> The number of nuclear transitions or disintegrations occurring in a given quantity of radioactive material per unit time. The SI unit of activity is s-1. The special name for the unit of activity is becquerel (Bq). The previously used special unit of activity, curie (Ci), is being replaced by the becquerel. 1 Bq = 2.7 x E-11 Ci. 1 Ci = 3.7 x E10 Bq. 4. Optical activity. (16 Dec 1997) |
| activity coefficient | <chemistry> The factor by which the value of a concentration of a solute must be multiplied to determine its true thermodynamic activity. (06 May 1997) |
| activity cycles | Bouts of physical irritability or movement alternating with periods of quiescence. It includes biochemical activity and hormonal activity which may be cellular. These cycles are shorter than 24 hours and include sleep-wakefulness cycles and the periodic activation of the digestive system. (12 Dec 1998) |
| polymorphic delta activity |
continuous irregular slow activity that is variable in duration and amplitude and may change little with sleep or other physiological alterations; it may be related to deafferentation of an area of the cortex, to metabolic factors, or to the presence of subcortical cerebral lesions and tumors.
