What does translocation mean biology?
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.
What does translocation cause?
Chromosomes are structures that carry genes, our units of heredity. When this type of translocation occurs, it can cause flaws in chromosomes. In another type of translocation, two chromosomes trade pieces with each other. Genetic translocations can cause serious disorders, including a type of leukemia.
What is translocation and why is it important?
Answers (1) (a) Transport of soluble product of photosynthesis from leaves to other parts of plants is called translocation. Translocation in plants takes place by vascular tissue called phloem. Translocation is essential because, without it, the food prepared by the leaves cannot reach other parts of the plant.
Which is an example of a translocation process?
Translocation is the movement of organic compounds from where they are made at their source, to where they are required at their sink. It is an active process which can be used to transport phloem up or down the plant. Roots that are absorbing mineral ions via active transport.
Where does the translocation of dissolved substances take place?
Translocation is the movement of dissolved substances, such as sucrose and amino acids, from parts of the plant where the substances are made to other parts of the plant where they’re needed. Translocation takes place in the phloem – transport vessels made up of two types of cell, sieve tube elements and companion cells.
Where does translocation take place in the phloem?
Translocation takes place in the phloem – transport vessels made up of two types of cell, sieve tube elements and companion cells. The parts of the plant which make these substances are referred to as sources (e.g. the leaves) and the parts of the plant which store or use the substances are called sinks (examples include bulbs and roots).
What does it mean to have a translocation chromosome?
A translocation is a chromosomal abnormality whereby there’s a break in the chromosome, one particular chromosome, and that chromosome will then fuse to a different chromosome.
