The change in chromosomal structure involving the transfer of one section of a chromosome to a non-homologous chromosome is known as a chromosomal translocation. This can result in genes being positioned in a different order or location, which can potentially disrupt gene function or regulation. Translocations are associated with various genetic disorders and can have significant effects on an individual's health and development.

Which part of chromosome exchange during meiosis centromere or telomere?
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
Why don't sex cells have homologous pairs of chromosomes?
you need one chromosome from one parent and one from the other parent. These homologous pairs each have the same genes but different alleles. For instance, one may code for black hair while the other codes for brown hair. You need both to be present in order to have both the parents traits.
Which type of inheritance involves traits linked to a sex chromosome?
It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.
When a child is born with a chromosomal mutation when did the mutation occurs?
during meiosis
What is the other name of homologous recombination?
It's also called "general recombination".Sometimes homologous recombination is mistakenly called "crossover", but crossover is a result of homologous recombination and not really synonymous.
Which part of chromosome exchange during meiosis centromere or telomere?
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
What is the type of assortment that involves the random distribution of homologous during meiosis?
independent
What happens during the Translocation mutation?
Translocation in the study of DNA involves the synthesis of proteins from ribosome structures. It starts when the mRNA leaves the nucleus (end of transcirption) and moves to the cytoplasm. From there a tRNA molecule carrying the corresponding amino acid for each codon on the mRNA forms the corresponding chain of proteins. This process continues until all of the codons on the mRNA are read by the tRNA. Each time a protein is bound to the tail end of the mRNA, an amino acid is added to the end of the link. By the end, a long chain of proteins has been constructed, based on the original DNA blueprint for that particular protein to be built. in shorter terms, a chromosome piece breaks off and reattaches to a non-homologous chromosome
What is the type of assortment that involves the random distribution of homologous chromosomes during meiosis?
Independent.
How is cri du chat inherited?
no, it is not inherited...... it is caused due to missing or deletion of short arm of chromosome 5p itself...... it does not depend on either of the parent. EDIT 90% of Cri du Chat is NOT inherited and involves the deletion listed above. An inherited variation occurs in 10% of Cri du Chat patients. This is the result of one of the parents being a carrier of a balanced chromosomal translocation or inversion involving the p arm of chromosome 5. If the mutated/altered chromosome is passed on to the offspring the child will exhibit Cri du Chat.
What are the two halves of a double chromosome structure called?
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
How are chromosomal mutations different than DNA mutations?
a gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia chromsome mutations have more pronounced effects and are due to a change in the number of chromosomes or a change in the structural effect that are inherited.. ex downs syndrom
Why don't sex cells have homologous pairs of chromosomes?
you need one chromosome from one parent and one from the other parent. These homologous pairs each have the same genes but different alleles. For instance, one may code for black hair while the other codes for brown hair. You need both to be present in order to have both the parents traits.
What structure in the cell involves energy production?
Nucleus
Which type of inheritance involves traits linked to a sex chromosome?
It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.
How do you use metaphase in a sentence?
The second stage in cell division is called the metaphase, and it involves chromosome attachment to spindle fibers.
Which event occurring in the life cycle of a bacterium most directly involves the replication of DNA?
the bacterium copies its single chromosome
