What is translocation and duplication?

Duplication is the type of mutation in which portion of genetic material or a chromosome is duplicated or replicated, resulting in multiple copies of that region, while translocation is chromosome abnormality

chromosome abnormality

A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder, is a missing, extra, or irregular portion of chromosomal DNA.

Chromosome abnormality - Wikipedia

caused by rearrangement of parts between non-homologous chromosomes.

What is a duplication in biology?

​Duplication

Duplication, as related to genomics, refers to a type of mutation in which one or more copies of a DNA segment (which can be as small as a few bases or as large as a major chromosomal region) is produced. Duplications occur in all organisms.

What defines translocation?

Listen to pronunciation. (TRANZ-loh-KAY-shun) A genetic change in which a piece of one chromosome breaks off and attaches to another chromosome. Sometimes pieces from two different chromosomes will trade places with each other.

What is the duplication process?

Duplicating is a process in which the desired number of copies is prepared from a master copy with the help of a duplicator. Duplicating differ from copying and reproduction. Copying or reproduction means preparation of one copy or few copies from the original.

What is translocation in evolution?

The importance of these mutations in evolution is… In heredity: Translocations. If a chromosome break occurs in each of two nonhomologous chromosomes and the two breaks rejoin in a new arrangement, the new segment is called a translocation.

Chromosomal Deletion, Inversion, Duplication and Translocation

How does gene duplication occur?

Gene duplication can occur as the result of an error in recombination or through a retrotransposition event. Duplicate genes are often immune to the selective pressure under which genes normally exist. This can result in a large number of mutations accumulating in the duplicate gene code.

What is translocation Brainly?

Translocation is the movement of sucrose and other organic materials from one place to another within the plant body. It occurs through the phloem generally and the concentration (pressure) gradient stimulates this process.

What is duplication and replication?

Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled.

What does duplicator mean?

Definition of duplicator

: one that duplicates specifically : a machine for making copies of graphic matter.

What is duplication example?

One example of a rare genetic disorder of duplication is called Pallister Killian syndrome, where part of the #12 chromosome is duplicated.

What is translocation in chemistry?

Translocation involves the movement of the ribosome along the mRNA in the 5′ → 3′ direction. Immediately after synthesis of the first peptide bond, the ribosomal A site contains dipeptidyl-tRNA while uncharged initiator tRNA remains in the P site.

What is translocation 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).

What is translocation for 7th class?

Translocation refers to the movement of nutrients from leaves to the other tissues in the plant. Water vapour is transported in transpiration. Sucrose is mainly transported in the translocation.

What is an example of 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.

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).

What happens in translocation mutation?

A translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome. This type of rearrangement is described as balanced if no genetic material is gained or lost in the cell. If there is a gain or loss of genetic material, the translocation is described as unbalanced .

What is genome duplication?

A whole genome duplication is exactly what it sounds like: an event which creates an organism with additional copies of the entire genome of a species. Regular cells of most organisms that reproduce sexually contain two copies of their entire genome (one inherited from each parent), a state known at being diploid.

What do you mean by duplicate gene?

Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene.

What is difference between replication and copying?

Duplicate (adjective) is identical to the original like a copy. Replicate is creating a similar copy, but not exactly like a duplicate.

What is translocation in plants Class 11?

It is the movement of substance in bulk from one point to another as a result of pressure difference between two points. The bulk movement of substances through the conducting or vascular tissue of plants is called Translocation.

What is translocation of food?

Translocation is the movement of nutrients and other 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.

What is ascent soap?

The ascent of sap in the xylem tissue of plants is the upward movement of water and minerals from the root to the aerial parts of the plant. The conducting cells in xylem are typically non-living and include, in various groups of plants, vessel members and tracheids.

Why is gene duplication important?

Abstract. Gene duplication is an important mechanism for acquiring new genes and creating genetic novelty in organisms. Many new gene functions have evolved through gene duplication and it has contributed tremendously to the evolution of developmental programmes in various organisms.

What are the types of duplication?

What disease does duplication cause?

23 duplication syndrome results from an extra copy of a region on the long (q) arm of chromosome 7 in each cell. This region is called the Williams-Beuren syndrome critical region (WBSCR) because its deletion causes a different disorder called Williams syndrome, also known as Williams-Beuren syndrome.
