Answer: Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants.
What is translocation for class 10th?
Translocation is the process by which plants deliver minerals, plant growth hormones, water, and organic substance over long distances throughout the plants (from leaves to other parts).
Where is translocation in biology?
Translocation is the movement of sugar produced in photosynthesis to all other parts of the plant for respiration and the other processes described above. This occurs in phloem cells.
What is an example of a translocation?
This newly formed chromosome is called the translocation chromosome. The translocation in this example is between chromosomes 14 and 21. When a baby is born with this type of translocation chromosome in addition to one normal 14 and two normal 21 chromosomes, the baby will have Down syndrome.

What are the three types of translocation?
1. simple translocations (one break involved) 2. reciprocal translocations (two breaks involved) 3. shift type translocations (three breaks involved) 4.
What are the different types of translocation?
There are two main types of translocation: a reciprocal translocation and a Robertsonian translocation.
Is Down syndrome translocation?
Translocation Down syndrome: This type accounts for a small percentage of people with Down syndrome (about 3%). This occurs when an extra part or a whole extra chromosome 21 is present, but it is attached or “trans-located” to a different chromosome rather than being a separate chromosome 21.
What is an example of crossing over?
For an example of crossing over, you can think of two pieces of foot-long rope lying on a table, lined up next to each other. Each piece of rope represents a chromosome.
What causes a translocation?
Translocation Down syndrome is a type of Down syndrome that is caused when one chromosome breaks off and attaches to another chromosome. In this case, there are three 21 chromosomes but one of the 21 chromosomes is attached to another chromosome.
What is translocation in human body?
Translocation means a change in location. It often refers to genetics, when part of a chromosome is transferred to another chromosome. Chromosomes are structures that carry genes, our units of heredity. When this type of translocation occurs, it can cause flaws in chromosomes.
What are the effects of translocation?
Translocations generate novel chromosomes. In a translocation, a segment from one chromosome is transferred to a nonhomologous chromosome or to a new site on the same chromosome. Translocations place genes in new linkage relationships and generate chromosomes without normal pairing partners.
Is translocation a mutation?
Department of Animal Science – Basic Animal Genetics
Translocations are chromosome mutations in which chromosome segments, and the genes they contain, change positions. Translocations can occur within a chromosome (intrachromosomal) or between chromosomes (interchromosomal).
Can you change DNA after birth?
Yes, absolutely. At the moment they are limited and are only used for important medical issues, but yes, we already can. Gene therapy is currently used for a number of genetic disorders, and it works by replacing the old genes with new, better genes, by means of a viral carrier.
Why is translocation important in plants?
Translocation in plants occurs in the vascular tissue known as phloem. Translocation is the movement of materials from leaves to other tissue throughout the plants. Without translocation, the food prepared by the plant can’t reach other parts of the plant.
How common are translocations?
Translocations are the most common type of structural chromosomal abnormalities seen in the general population, having a frequency of about 1/1000 live births. Two types of chromosomal translocations are described: Robertsonian translocations and reciprocal translocations [1].
Can I have a baby translocation?
It can be an inherited trait or can occur in a fetus even when neither parent is affected by the condition. New translocations can happen when sperm or egg cells are forming or immediately after fertilization.
Can you have a healthy baby with translocation?
Conclusions: Balanced translocation carriers suffer from poor pregnancy prognosis. Couples with homologous Robertsonian translocations have little chance to give birth to normal/balanced offsprings.
How do you test for translocation?
Genetic testing is available to find out whether a person carries a translocation. A simple blood test is done, and cells from the blood are examined in a laboratory to look at the arrangement of the chromosomes. This is called a karyotype test.
How does translocation affect fertility?
Balanced translocation carriers are burdened with fertility issues due to improper chromosome segregation in gametes, resulting in either implantation failure, miscarriage or birth of a child with chromosomal disorders.
What is translocation in pregnancy?
A balanced or chromosomal translocation is a condition in which part of a chromosome has broken off and reattached in another location. In other words, it means that sections of two chromosomes have switched places.
