Translocation in Biological Definition

Patau syndrome

... of the chromosome. Patau syndrome due to a translocation can be inherited. An unaffected person can carry ... This rearrangement is called a balanced translocation because there is no extra material from ... syndrome, people who carry this type of balanced translocation are at an increased risk of having children with ...

Proton pump

... provided by electron transfer or photosynthesis power this translocation of protons. For example, the translocation of protons by cytochrome c oxidase is powered by reducing equivalents ...

Cancer

... promote cancer when "switched on" by a mutation, whereas tumor suppressor genes prevent cancer unless "switched off" by a mutation. Chromosomal translocation , such as the Philadelphia chromosome , is a special type of mutation and may involve oncogenes or tumor suppressor genes. In general, mutations in ...

Infertility

... for another third, combined male and female infertility for another 15%, and the remainder of cases are "unexplained" 2 . A Robertsonian translocation in either partner may cause recurrent abortions or complete infertility. Female infertility Factors relating to female infertility are: ...

Phloem

... by negative pressures (tension) most of the time, movement through the phloem is driven by positive hydrostatic pressures . This process is termed translocation , and is accomplished by a process called phloem loading and unloading . Cells in a sugar source "load" a sieve-tube element by actively ...

Protein biosynthesis

... first tRNA is released, but the amino acid that is attached to the first tRNA is now moved to the second tRNA, and binds to its amino acid. This translocation continues on, and a long chain of amino acid (protein), is formed. When the entire unit reaches the end codon on the mRNA, it falls apart and a ...
