   Dec 30, 2022 · This mechanism is carried out by Activation-Induced Cytidine Deaminase (AID), which converts cytidines to uracils, generating a G:U mismatch that is “corrected” by repair polymerases without strong error-correction.

   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.

   Oct 31, 2023 · Cytologists have characterized numerous structural rearrangements in chromosomes, but chromosome inversions and translocations are the most common. Both are identified during meiosis by the adaptive pairing of rearranged chromosomes with their former homologs to maintain appropriate gene alignment.

   What causes DNA rearrangements?

   • The DNA rearrangements are caused by a set of mechanisms that are collectively called genetic recombination. Two broad classes are commonly recognized— general recombination and site-specific recombination. In this part of the chapter we discuss the first of these two mechanisms; in the next part, we consider the second mechanism.

   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.

   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.

   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.
