What Are The Four Types Of Chromosomal Rearrangements? Chromosomal rearrangements encompass several different classes of events: deletions, duplications, inversions; and translocations. What are the four types of chromosomal rearrangements that can transpire? Today and next time, we’ll talk about chromosomal rearrangements – reorganizations of chromosome structure that can affect expression of more than one gene
Can Homologous Recombination Repair Double-Strand Breaks? DNA double-strand breaks are repaired by means of two main mechanisms: nonhomologous end joining and homologous recombination (see Figure 1). Both mechanisms operate in all eukaryotic cells that have been examined but the relative contribution of each mechanism varies. Can homologous recombination repair broken replication forks? Homologous recombination is
Does Repair By Nonhomologous End Joining Change Dna Length? Our results suggest that NHEJ is a faster and more efficient DSB repair pathway than HR. Why do cells use non-homologous end joining? Nonhomologous end-joining is another DNA repair mechanism that resolves DSBs. Since it relies on no sequence homology or short overhangs at DSBs, it
