translocation
transfer of soluble materials through the sieve tubes of the phloem of vascular plants; the exchange of parts of chromosomes

Translocation of Food
Food and other organic substances (e.g., some plant hormones and even messenger RNAs [Link]) manufactured in the cells of the plant are transported in the phloem.
Translocation
Translocation is a type of chromosomal abnormality in which a chromosome breaks and a portion of it reattaches to a different chromosome. Chromosomal translocations can be detected by analyzing karyotypes of the affected cells.

A chromosomal configuration in which (usually) the ends of two non- homologous chromosomes have become exchanged. A translocation in which part of one chromosome is exchanged with a part of a separate non-homologous chromosome.
Translocation Down Syndrome
A translocation is the movement of a chromosomal segment from one chromosome to another nonhomologous chromosome.
Five percent of Down Syndrome cases involve a translocation.
translocation 1) The movement of a segment from one chromosome to another without altering the number of chromosomes. 2) the movement of þuids through the phloem from one part of a plant to another, ...
translocation
[L. trans, across + locare, to put or place]
(1) An aberration in chromosome structure resulting from an error in meiosis or from mutagens; attachment of a chromosomal fragment to a nonhomologous chromosome.
Translocation A mutation which has moved one segment of a chromosome to a different position in the genome. A reciprocal translocation involves the exchange of material between two chromosomes.
Translocation. The movement or reciprocal exchange of large-chromosomal segments, typically between two different chromosomes.
Transposable genetic element. See Transposon.
Translocation A mutation in which a large segment of one chromosome breaks off and attaches to another chromosome.

Transposable element A class of DNA sequences that can move from one chromosomal site to another.
Translocation
Transfer of a segment of a chromosome to a non homologous chromosome. Translocations are usually reciprocal. (Cf. Interchange.)

Balanced Translocation Occurs when two chromosomes break and exchange places leaving the same amount of genetic material. An individual with a balanced translocation will be unaffected, but children may be affected in a variety of ways.
Occasional cases result from a translocation in the chromosomes of one parent. Remember that a translocation occurs when one chromosome (or a fragment) is transferred to a non-homologous chromosome.
