1. Amniocentesis
A method of prenatal testing in which amniotic fluid is withdrawn from the uterus through a needle. The fluid and the fetal cells it contains are analyzed to detect biochemical or chromosomal disorders.

2. Autonomously replicating sequence (ARS)
This is a chromosomal sequence that allows plasmid s to replicate on their own in yeast .

3. Balanced translocation
A number of the chromosomal mutations called translocations, where a segment of DNA abnormally becomes attached to the wrong chromosome , which results in two nonhomologous chromosome s being able to cross over , something which normally can occur only between homologous chromosomes.

4. Chorionic villi sampling (CVS)
A method of prenatal testing in which fetal cells from the fetal side of the placenta (chorionic villi) are extracted and analyzed for chromosomal and biochemical defects.

5. Chromosomal aberration
Any abnormality of a chromosome 's number or structure.

6. Chromosomal mutation
Can refer to any of a number of DNA mutation s which results in a change in the protein encoded by the mutated gene , such as point mutation s, insertion or deletion mutation s ( frameshift mutation s), or nonsense mutation s. More often this refers to mutations involving chromosome s, such as the inversion of part of one chromosome such that the inverted part no longer matches with its homologous pair , a translocation of one part of a chromosome to a different chromosome, deletions of parts of chromosomes, or accidents which happen during the division of the nucleus like the unequal portioning of chromosomes between the daughter cells.

7. Chromosome walking
A technique in which, working from a flanking DNA marker , overlapping clone s are successively identified that span a chromosomal region of interest.

8. Chromosomes
The self-replicating genetic structures of cells containing the cellular DNA that bears in its nucleotide sequence the linear array of gene s. In prokaryote s, chromosomal DNA is circular, and the entire genome is carried on one chromosome. Eukaryotic genome s consist of a number of chromosomes whose DNA is associated with different kinds of protein s.

9. Clastogen
A clastogen is any substance which causes chromosomal breaks.

10. Contig map (contiguous map)
A map depicting the relative order of a linked library of small overlapping clones representing a complete chromosomal segment.
