Do Dna Repair Enzymes Target Rrna?

by

Do Dna Repair Enzymes Target Rrna? Genetic information can be stored stably in DNA sequences only because a large set of DNA repair enzymes continuously scan the DNA and replace any damaged nucleotides. Most types of DNA repair depend on the presence of a separate copy of the genetic information in each of the two

Does Mismatch Repair Need Ligase?

Does Mismatch Repair Need Ligase? A second complex cuts the DNA near the mismatch, and more enzymes chop out the incorrect nucleotide and a surrounding patch of DNA. A DNA polymerase then replaces the missing section with correct nucleotides, and an enzyme called a DNA ligase seals the gap 2. Mismatch repair. What enzymes are
