How Do Eukaryotes Repair Damaged Dan? nucleotide excision repair (NER How does damaged DNA get repaired? Most damage to DNA is repaired by removal of the damaged bases followed by resynthesis of the excised region. Some lesions in DNA, however, can be repaired by direct reversal of the damage, which may be a more efficient
How Do Enzymes Repair Dna Damage? Thus, enzymes known as DNA glycosylases remove damaged bases by literally cutting them out of the DNA strand through cleavage of the covalent bonds between the bases and the sugar-phosphate backbone. The resulting gap is then filled by a specialized repair polymerase and sealed by ligase. How is damaged
How Do Bacteria Repair Dna Damage? In normal healthy cells the LexA protein binds to a certain section of the bacterial DNA called the ‘SOS box’ which codes for over 50 genes while RecA floats around the cell looking for damaged DNA. If it finds any, it binds to it and stimulates the breaking of
