   Dec 30, 2022 · (A) rearrangement of α chain and (B) β chain (C) protein structure of TCR. The enzyme that produces this diversity is a complex called the V(D)J recombinase. The recombination occurs in two parts: first double-stranded breaks are made at re- combination signal sequence (RSS) sites, then the breaks are repaired by the general double-stranded break repair mechanism.

   If the rearrangement involves a gene that controls cell growth, the affected cell may divide uncontrollably, eventually leading to a tumour. However, not all rearrangements cause harm; some do not affect the cell. How do rearrangements cause cancer? Rearrangements can bring together two different genes, creating a fusion gene. The fusion gene ...

   Chromosomal Rearrangements. A chromosomal rearrangement means that pieces of chromosomes are missing, duplicated (there are extra copies), or moved around. The effects vary. They depend on which chromosome pieces are involved and how they are rearranged. Some have no effect, some are incompatible with life, and others are somewhere between.

   DNA Rearrangements. Homologous recombination results in the reassortment of genes between chromosome pairs without altering the arrangement of genes within the genome. In contrast, other types of recombinational events lead to rearrangements of genomic DNA. Some of these DNA rearrangements are important in controlling gene expression in ...

   What is the difference between gene amplification and DNA rearrangement?

   • The DNA rearrangements that have been discussed so far alter the position of a DNA sequence within the genome. Gene amplification may be viewed as a different type of alteration in genome structure; it increases the number of copies of a gene within a cell.

   How does DNA rearrangement affect gene evolution?

   • Since LINEs can integrate into active genes, the associated transposition of cellular DNA sequences can lead to the formation of new combinations of regulatory and/or coding sequences and contribute directly to the evolution of new genes. The DNA rearrangements that have been discussed so far alter the position of a DNA sequence within the genome.

   Why are DNA rearrangements important?

   • Some of these DNA rearrangements are important in controlling gene expression in specific cell types; others may play an evolutionary role by contributing to genetic diversity. The discovery that genes can move to different chromosomal locations came from Barbara McClintock's studies of corn in the 1940s.

   What is a balanced chromosomal rearrangement?

   • Rearrangements fall broadly into two categories: balanced and unbalanced. A person with a balanced chromosomal rearrangement has a complete set of genetic information. However, some chromosome pieces have been moved around. Most of the time, people who have a balanced chromosomal rearrangement are perfectly healthy.

   What is the difference between a deletion and a rearrangement?

   • Rearrangement is an abnormality that involves a structural alteration in a chromosome through things like deletions, inversions, translocations, or duplications. Deletions refer to the removal of a segment of DNA from a chromosome.
