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.

Translocation events monitored by RelE cleavage of the A-site codon ...

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:.
Once the peptide bond has formed, the first tRNA detaches and travels into the cytoplasm to pick up another amino acid.

Translocation - whole system ratchets down so that the tRNA formerly in the A site is now in the P site
The cycle repeats itself until as STOP codon is reached
Termination - when a stop codon is encountered ...

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 Transfer of a segment of one chromosome to another chromosome.
transpiration Loss of water from the leaves of a plant; creates an osmotic gradient that draws nutrient-laden water up from the roots. DIAGRAM ...

Translocation Pertaining to a novel chromosome formed by breakage and reunion of DNA molecules into a non- wild-type configuration (see Chapter 5).
See Translocation in the MGI Glossary.

Translocation. The movement or reciprocal exchange of large-chromosomal segments, typically between two different chromosomes.
Transposable genetic element. See Transposon.

Translocation - The process in which the ribosome moves three nucleotides down an mRNA strand in the 3' direction. Process is catalyzed by the hydrolysis of GTP to GDP.

In the event of procedures which allowed easy enumeration of chromosomes, discoveries were quickly made related to aberrant chromosomes or chromosome number.

Translocation, I hate some of the names that scientists come up with, rather than just saying a it moved they say translocation see a and b have been swapped over from the long chromosome to the shorter chromosome and mno has been swapped over to the ...

translocation Moving animals from one location to another, for instance to determine whether and how soon they shift their activity cycle to match the photoperiod and/or other features in their new location.

During translocation, the ribosome moves the tRNA with the attached polypeptide from the A site to the P site.

A Robertsonian translocation in either partner may cause recurrent abortions or complete infertility.

Transgenic
Pertaining to an animal or locus that contains a transgene.
Translocation
Pertaining to a novel chromosome formed by breakage and reunion of DNA molecules into a non-wild-type configuration.

Translocation Chromosomal rearrangement in which a piece of one chromosome is transferred to another one.
Triploidy The presence of a full extra set of chromosomes. Often lethal.

Also chromosomal translocation may become important. In this mechanism, ...

Down syndrome -- a type of mental deficiency due to trisomy (three copies) of autosome 21, a translocation of 21 or mosaicism.

Structural genetic variation — A term that encompasses variety of large-scale genomic aberrations, including segmental rearrangements, translocations or inversions, and DNA copy-number variants (CNVs).

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.

(fluorescence in situ hybridization): One of the more modern methods in cytogenetics, which uses fluorescence-labelled chromosome-specific DNA, probes to detect translocations, inversions, deletions, ...

An antibiotic that inhibits protein synthesis by binding to the 30s ribosomal subunit and preventing translocation. KanR is usually due to a cytoplasmic aminoglycoside phosphotransferase that inactivates kanamycin by covalently phosphorylating it.

Another example is the translocation of vesicles containing neurotransmitters by microtubules to the tips of nerve cell axons.

The second tRNA has now moved into place and the now free tRNA has been released. Translocation can take place: it is the transfer of the newly formed dipeptide into the peptidyl site (the first one, also called donor site) (Diagram 4) when the ...

Sometimes, a chromosome may break and then be rejoined incorrectly to another chromosome - this is known as a chromosomal translocation.
Such chromosomal rearrangements complicate synapsis and can lead to a failure of meiosis, and hence sterility.

These processes include polarization, protrusion and adhesion, translocation of the cell body and retraction of the rear. These processes are coordinated and integrated by extensive transient, signaling networks.

not dated), and other species that have large chromosomal differences can still interbreed (Nevo et al. 1994). DNA aligns according to local sequence rather than large-scale chromosome structure, and this is why inversions and translocation in parts ...
