Glossary of botanical terms Translocation is the process within plants that functions to deliver nutrients and other molecules over long distances throughout the organism. Translocation occurs within a series of cells known as the phloem pathway, or phloem transport system, with phloem being the principal food-conducting tissue in vascular plants. Nutrients are translocated in the phloem as solutes in a solution called phloem sap.

Vascular Tissue Translocation. the transport of sucrose and other organic molecules through the phloem of a plant For example, during winter storage, plants transport carbohydrates into their roots, and then back to the trunk and branches in the spring.ater moves through the root cells or through the intercellular spaces within the roots and enters the xylem Water is then transported in the xylem tissue up through the roots into the stem As xylem tissue carrying water and minerals enters the leaf, the conducting vessels branch into the numerous veins.

- Posttranslational translocation in eukaryotes. During cotranslational translocation, the ribosome provides the motive power that pushes the growing peptide into the ER lumen. During posttranslational translocation, additional proteins are necessary to ensure that the peptide moves unidirectionally into the ER membrane.

- Background—Gut translocation of bacteria has been shown in both animal and human studies. Evidence from animal studies that links bacterial translocation to the development of postoperative sepsis and multiple organ failure has yet to be confirmed in humans.

What are translocation mutations? A mutation is a permanent change in the DNA sequence of a gene. Mutations in a gene's DNA sequence can alter the amino acid sequence of the protein encoded by the gene. How d…oes this happen? Like words in a sentence, the DNA sequence of each gene determines the amino acid sequence for the protein it encodes.

Transposon Tagging (Molecular Biology) Transposon Tagging (Molecular Biology) Transposons are mobile genetic elements that move (transpose) from one region of the genome to another. Transposons are used as tools for gene cloning because insertion of a transposon into a gene disrupts its function, often producing a visible mutant phenotype.

Translation (biology) Translation (biology) In molecular biology and genetics, translation is the process in which ribosomes in a cell's cytoplasm create proteins, following transcription of DNA to RNA in the cell's nucleus. The entire process is a part of gene expression.

- A substitution is a mutation that exchanges one base for another (i.e., a change in a single chemical letter such as switching an A to a G). Such a substitution could: 1  change a codon to one that encodes a different amino acid and cause a small change in the protein produced.2  For example, sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced. For example, sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced. 2  change a codon to one that encodes the same amino acid and causes no change in the protein produced. 3  These are called silent mutations.

Cotranslational protein translocation This also results in the translocation of the amino terminus of the protein into the ER membrane lumen. This would seem to break the rule of co-translational translocation which has always held for mammalian proteins targeted to the ER.his also results in the translocation of the amino terminus of the protein into the ER membrane lumen.

- Translocation Down syndrome refers to the type of Down syndrome that is caused by rearranged chromosome material.In this case, there are three # 21 chromosomes, just like there are in trisomy 21, but one of the 21 chromosomes is attached to another chromosome, instead of being separate.The extra copy of the # 21 chromosome is what causes the health problems that are associated with Down syndrome.henever a translocation is found in a child, the parents' chromosomes are studied to determine whether the translocation was inherited or not. If one parent has the translocation chromosome, then the doctor knows the baby inherited the translocation from that parent.

- In group translocation, chemical modification of molecule to be transport is done into the cell. Group translocation is type of active transport because metabolic energy … is used during uptake of the molecule,. In bacteria the best known group translocation system is phosoenolpyruate: sugar phosphotransferase system (PTS) PEP + SUGAR ----- PYRUATE + sugar-phosphate In E.coli the PTS consists of two enzyme and a low molecular weight heat-stable protein(HPr)

Chromosomal translocation This is known as a 'translocation Downs'. This is due to a mis-segregation (nondisjunction) during gametogenesis. The mother has a higher (10%) risk of transmission than the father (1%). Robertsonian translocations involving chromosome 14 also carry a slight risk of uniparental disomy 14 due to trisomy rescue.

translocation translocation A change in the arrangement of genetic material, altering the location of a chromosome segment. The most common forms of translocations are reciprocal, involving the exchange of chromosome segments between two nonhomologous chromosomes.

- In this case, a substance is chemically altered during its transport across a membrane so that once inside, the cytoplasmic membrane becomes impermeable to that substance and it remains within the cell. An example of group translocation in bacteria is the phosphotransferase system.

Italy Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials. World Encyclopedia 2005, originally published by Oxford University Press 2005. translocation In vascular plants, the movement of food materials in solution through the tissues from one part of the plant to another.

Translocation Glucose , the sugar found in the circulatory system of animals, is not translocated. In order to accommodate the flow of sap, the internal structure of the conducting cells of the phloem, the sieve elements, is drastically altered.
