| chromosome walking | A procedure to find and sequence a gene whose approximate position in a chromosome is known by classical genetic linkage studies. Starting with the known sequence of a gene shown by classical genetics to be near to the novel gene, new clones are picked from a genomic library by hybridisation with a short probe generated from the appropriate end of the known sequence. The new clones are then sequenced, new probes generated and the process repeated until the gene of interest is reached. (18 Nov 1997) |

| chromosomes | The self-replicating genetic structures of cells containing the cellular DNA that bears in its proteins. (09 Oct 1997) |
| chromosomes in multiple miscarriages | Couples who have had more than one miscarriage (spontaneous abortion) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| chromosomes, archaeal | Structures within the nucleus of archaeal cells consisting of or containing DNA, which carry genetic information essential to the cell. (12 Dec 1998) |
| chromosomes, bacterial | Structures within the nucleus of bacterial cells consisting of or containing DNA, which carry genetic information essential to the cell. (12 Dec 1998) |
| chromosomes, fungal | Structures within the nucleus of fungal cells consisting of or containing DNA, which carry genetic information essential to the cell. (12 Dec 1998) |
| chromosomes, human | The structures within the human cell nucleus that contain the hereditary material, DNA. There are 46 chromosomes normally present in the human, including two which determine the sex of individual, xx for the female and xy for the male. Human chromosomes are classified into groups sharing structural similarity in terms of length from the centromere. (12 Dec 1998) |
| chromosomes, human, 1-3 | One of the seven groups of chromosomes containing three pairs conventionally named pairs 1, 2, and 3. The chromosomes in this group, also called group a, are large chromosomes with centromeres approximately in the middle. (12 Dec 1998) |
| chromosomes, human, 13-15 | The fourth of the seven groups of chromosomes containing three pairs conventionally named pairs 13, 14, and 15. The chromosomes in this group, also called group d, are medium sized with centromeres in the acrocentric position. (12 Dec 1998) |
| chromosomes, human, 16-18 | The fifth of the seven groups of chromosomes containing three pairs conventionally named pairs 16, 17, and 18. The chromosomes in this group, also called group e, are rather short and submetacentric. (12 Dec 1998) |
| chromosomes, human, 19-20 | The sixth of the seven groups of chromosomes containing two pairs conventionally named pairs 19 and 20. The chromosomes in this group, also called group f, are short and metacentric. (12 Dec 1998) |
| chromosomes, human, 21-22 | The seventh of the seven groups of chromosomes containing two pairs conventionally named pairs 21 and 22, and the y chromosome. The chromosomes in this group, also called the g group, are very short and acrocentric. (12 Dec 1998) |
| chromosomes, human, 4-5 | The second of the seven groups of chromosomes containing two pairs conventionally named pairs 4 and 5. The chromosomes in this group, also called group b, are large with centromeres in the submetacentric position. (12 Dec 1998) |
| chromosomes, human, 6-12 | The third of the seven groups of chromosomes containing seven pairs conventionally named pairs 6, 7, 8, 9, 10, 11, and 12, and the x chromosome. The chromosomes in this group, also called group c, are medium sized with centromeres in the submetacentric position. The x chromosome most resembles 6. This group presents the major difficulty in the identification of individual chromosomes. (12 Dec 1998) |
| chromosomes, human, pair 1 | One of the three pairs in the first group (or group a) of human chromosomes according to the current classification for humans. (12 Dec 1998) |

| chromium 51 |
a radioactive isotope of chromium, atomic mass 51, having a half-life of 27.7 days; it decays by electron capture, emitting gamma rays (0.32 MeV), and is used to label red blood cells for measurement of red cell mass or volume, survival time, and sequestration studies, and for the diagnosis of gastrointestinal bleeding, and is used to label platelets to study their survival. It has also been used to label human serum albumin for measurements of gastrointestinal protein loss.

| chronic |
a condition of the bladder occurring predominantly in women, with an inflammatory lesion, usually in the vertex, and involving the entire thickness of the wall, appearing as a small patch of brownish-red mucosa, surrounded by a network of radiating vessels. The lesions, known as Fenwick-Hunner or Hunner ulcers, may heal superficially, and are notoriously difficult to detect. Typically, there is urinary frequency and pain on bladder filling and at the end of micturition. ...
