   Like other programmed gene rearrangements, however, gene amplification is a relatively infrequent event that occurs in highly specialized cell types; it is not a common mechanism of gene regulation. Gene amplification also occurs as an abnormal event in cancer cells, where it results in the increased expression of genes that contribute to uncontrolled cell growth.

   Oct 31, 2023 · Figure 13.2B. 1 13.2 B. 1: Inversion heterozygotes: When one chromosome undergoes an inversion, but the other does not, one chromosome must form an inverted loop to retain point-for-point interaction during synapsis. This inversion pairing is essential to maintaining gene alignment during meiosis and to allow for recombination.

   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.

   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.

   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.

   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.

   Which types of DNA rearrangements are recognized in prokaryotic and eukaryotic cells?

   • Several types of DNA rearrangements, including the transposition of elements initially described by McClintock, are now recognized in both prokaryotic and eukaryotic cells.
