Which chromosomal defect is caused when part of a chromosome breaks off at either end and attaches to another chromosome?
The chromosomal defect you are describing is known as a translocation. In a translocation, a segment of one chromosome breaks off and is reattached to a different chromosome, which can lead to genetic imbalances and various genetic disorders. This type of defect can occur in both somatic cells and germ cells and is often associated with certain cancers and congenital conditions.

What part of a chromosome breaks off and attaches to another chromosome is?
The part of a chromosome that breaks off and attaches to another chromosome is called a chromosomal segment or chromosomal fragment. This process can occur during events such as crossing over in meiosis or through chromosomal rearrangements, like translocations. These alterations can lead to genetic diversity but may also result in genetic disorders or cancer if they disrupt important genes.
What is chromosomal translocation?
Chromosomal translocation is a genetic event where a segment of one chromosome breaks off and attaches to another chromosome. This rearrangement can lead to changes in gene expression and may result in genetic disorders or cancers, such as leukemia. Translocations can be reciprocal, involving two chromosomes exchanging segments, or non-reciprocal, involving the transfer of a segment without an equal exchange. These alterations can disrupt normal cellular functions and contribute to various diseases.
If Rett syndrome is a chromosomal abnormality what is the abnormality?
Rett syndrome is not primarily caused by a chromosomal abnormality, but rather a genetic mutation in the MECP2 gene located on the X chromosome. This gene provides instructions for making a protein that is important for brain development. Mutations in the MECP2 gene disrupt the production of this protein, leading to the characteristic features of Rett syndrome.
What is it called when one chromosome breaks off and is added to a different chromosome?
translocation i'm doing the same worksheet for my finals study guide, and in my book it discussed this.
Mutations often causing conditions like leukemia and lymphoma are the result of a certain change in non homologous chromosomes. This type of change is refered to as?
This type of change is referred to as a chromosomal translocation. In this process, a segment of one chromosome breaks off and attaches to a non-homologous chromosome, leading to the disruption of normal gene function and potentially resulting in cancers such as leukemia and lymphoma. These translocations can activate oncogenes or inactivate tumor suppressor genes, contributing to uncontrolled cell proliferation.
What part of a chromosome breaks off and attaches to another chromosome is?
The part of a chromosome that breaks off and attaches to another chromosome is called a chromosomal segment or chromosomal fragment. This process can occur during events such as crossing over in meiosis or through chromosomal rearrangements, like translocations. These alterations can lead to genetic diversity but may also result in genetic disorders or cancer if they disrupt important genes.
If a piece of DNA breaks off a chromosome and attaches itself to a nonhomologous chromosome at another location what type of change has occured?
If a piece of DNA breaks off a chromosome and attaches itself to a nonhomologous chromosome at another location translocation is the type of change that has occurred. The chromosomal pieces are moved to a new location.
How are the three chromosomal aberrations differ from each other?
The three main types of chromosomal aberrations are deletions, duplications, and translocations. Deletions involve the loss of a segment of a chromosome, which can lead to gene loss and associated disorders. Duplications entail the presence of an extra segment of a chromosome, resulting in gene redundancy that may disrupt normal function. Translocations occur when a segment of one chromosome breaks off and attaches to another chromosome, potentially leading to genetic imbalances and various diseases, including cancer.
What do the four types of chromosomal mutations do?
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome. Duplication is where a segment of a chromosome is copied. Inversion is where a section of a chromosome is reversed. Translocation is the process in where a part of one chromosome breaks off and attaches to a non-homologous chromosome.
What are four types of chromosomal mutations?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
What is chromosomal translocation?
Chromosomal translocation is a genetic event where a segment of one chromosome breaks off and attaches to another chromosome. This rearrangement can lead to changes in gene expression and may result in genetic disorders or cancers, such as leukemia. Translocations can be reciprocal, involving two chromosomes exchanging segments, or non-reciprocal, involving the transfer of a segment without an equal exchange. These alterations can disrupt normal cellular functions and contribute to various diseases.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
If Rett syndrome is a chromosomal abnormality what is the abnormality?
Rett syndrome is not primarily caused by a chromosomal abnormality, but rather a genetic mutation in the MECP2 gene located on the X chromosome. This gene provides instructions for making a protein that is important for brain development. Mutations in the MECP2 gene disrupt the production of this protein, leading to the characteristic features of Rett syndrome.
What occurs when a segment breaks of chromosome breaks off and reattaches to another chromosome?
This is known as a chromosomal translocation, which can result in genetic material being exchanged between chromosomes. Translocations can lead to disruptions in gene expression and potential genetic disorders. Depending on the specific genes involved, translocations can have diverse effects on an individual's health.
When part of a chromosome breaks off and is added to a diffrent chromosome the result is?
I think this might be called chromosomal rearrangement, and this caused genetic variation in individuals, because a new segment of DNA is being inserted into a random spot on the chromosome, creating a new genetic sequence in that area. Its Translocation.
What is the difference between nondisjunction and translocation mutations?
Nondisjunction is a mutation where chromosomes fail to separate properly during cell division, leading to an abnormal number of chromosomes in daughter cells. Translocation is a mutation where a segment of one chromosome breaks off and attaches to another chromosome, potentially disrupting the normal genetic sequence.
