The difference between deletion duplication inversion and translocation?

Deletions are a loss of all or part of a chromosome. Duplications produce extra copies of parts of a chromosome. Inversions reverse the direction of parts of a chromosome. Translocations occur when part of one chromosome breaks off and attaches to another.

Gene A occurs on chromosome 5 gene B on chromosome 21 Therefore these two parts of a chromosome cannot be what?


What is a list of the 3 parts of a chromosome?

Telomere - The ends of the chromosome. Centromere - The primary constriction of the chromosome. Chromatid - A single molecule of DNA. The centromere also divides the chromosome into a short arm (p) and a long arm (q).

What are the parts of a chromosome that control inherited traits?

The parts of a chromosome that control inherited traits is referred to as genes. There are many types of inherited traits, some visible while the others are invisible,

Suppose your looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15?

An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.

Mutation that occurs at the chromosome level resulting in changes in the gene distribution?

Chromosomal mutationAneuploidyAneuploidy occurs when a cell has the wrong number of chromosomes either due to an extra or missing chromosome. This type of problem can occur during the anaphase part of M phase. Through a process called nondisjunction the chromosome pairs may not separate properly causing one of the daughter cells to receive both copies of a chromosome and the other daughter cell receives no copies of that chromosome. Therefore, one daughter cell will have an extra chromosome and the other daughter cell will have a missing chromosome. Also, this problem can occur if there is a lag during anaphase. When the pairs of chromosomes separate to each side of the cell, a chromosome may travel too slow which would cause it to not be incorporated into the new cell. This new cell would be missing a chromosome. DeletionChromosome Deletions occur when the cell is missing a portion of a chromosome. This type of problem can occur during S phase if there is a problem during DNA replication or other parts of interphase if the DNA is damaged. DuplicationChromosome Duplications occur when a cell has a repeated portion of a chromosome which causes the cell to have extra information. This type of problem can occur during S phase if there is a problem during DNA replication. InversionChromosome Inversions occur when a piece of a chromosome breaks and that piece is reattached in the opposite orientation. This type of problem can occur during interphase if the DNA is exposed to damage that causes DNA breakage. InsertionChromosome Insertions occur when a piece of a chromosome that had broken reattaches in a location where this genetic material is not typically found. This type of problem can occur during interphase if the DNA is broken and then repaired by attaching to a different location. TranslocationThere are two types of translocations: reciprocal and robertsonian. A reciprocal translocation occurs when two nonhomologous chromosomes break and then switch genetic material. A robertsonian translocation occurs when two chromosomes break on the p arm near the centromere and then the two q arms attach together while the p arms are lost. Either of these types of translocation can occur at any point during the cell cycle.

What are the differences between translocation and inversion mutations?

Translocation is when nonhomologous chromosomes exchange segments, like when chromosome 1 exchanges parts with chromosome 5. Inversion is when broken segments of the chromosome is inserted backwards.
