a map of a stretch of DNA with ordered landmarks a known distance from each other; the ultimate physical map would be the base sequence of the entire chromosome.
phys·i·cal map(fiz'i-kăl map)
A map of a stretch of DNA with ordered landmarks a known distance from each other; the ultimate physical map would be the base sequence of the entire chromosome.
physical map(of genome) a map consisting of an ordered set of DNA fragments representing the genome or a particular, localized genomic region. A physical map may be a restriction map, comprising of an ordered set of DNA fragments generated by using RESTRICTION ENZYMES. The map indicates the position and number of restriction sites for specific enzymes. For large genomes, restriction enzymes that cleave the DNA infrequently are used to generate large restriction fragments that can be ordered in a macro-restriction map. An ordered clone map, or clone contig map consists of an overlapping collection of cloned DNA fragments comprising all the DNA of the genome or part of the genome.See CLONE CONTIG SEQUENCING METHOD.
pertaining to the body, to material things, or to physics.
the physical causes of disease. Includes altitude, radiation, wetness, exercise, fire, electricity including lightning.
a preliminary diagnosis made solely on the basis of a physical examination. Often all that is possible in private practice.
examination of the bodily state of a patient by ordinary physical means, as inspection, palpation, percussion and auscultation.
see physical exhaustion.
results of a physical examination. Observations made visually, by auscultation, palpation, smell, percussion, succussion and ballottement.
quality of being able to perform physically, to turn in a good physical performance. Best tested by performance but in horses can be vaguely predicted by a series of tests including hemoglobin content of blood, heart size, duration of the QRS interval on an ECG, and low levels of muscle enzymes in blood.
physical agencies that cause disease. These include trauma, stress (physical as in stress fracture of long bones in horses), hyperthermia (as a cause of congenital defects), persistent wetting, high altitude, lightning stroke, electrocution, bushfire and fire injury, volcanic eruption and exposure to radiation.
in genetics, determination of the array of genes within a DNA segment of a chromosome.
the use of halters, collars and chains, ropes, harness, twitches of various sorts, squeeze cages, hog holders, dog catchers and many more devices. As distinct from the use of analeptic agents—chemical restraint.
one who is skilled in the physical and therapeutic techniques of helping to alleviate suffering from muscle, nerve, joint and bone diseases and from injuries and to overcome or prevent disabilities. Among the procedures used by the physical therapist are exercise to increase strength, endurance, coordination, and range of motion; electrical stimulation to activate paralyzed muscles; massage, vibrators and many other patented devices to try to improve the circulation and condition of a part. Called also physiotherapist.
