Original sentence: REDIRECT Microhomology-mediated end joining
Edited sentence: As this method is only way of identifying if the two strands are related is based on microhomology down/up-stream from the site of breakage, it does not identify any missing base pairs which may have been lost during the break and even removes nucleotides (flaps) in order to ligate the strand.DNA double strand break repair in human bladder cancer is error prone and involves microhomology-associated end-joining.Distinctive differences in DNA double-strand break repair between normal urothelial and urothelial carcinoma cells.In most cases a cell uses MMEJ only when the NHEJ method is unavailable or unsuitable due to the disadvantage posed by introducing deletions into the genetic code.MMEJ is an error-prone method of repair and results in deletion mutations in the genetic code which may initiate the creation of oncogenes that could lead to the development of cancer.MMEJ is distinguished from the other repair mechanisms by its use of 5 - 25 base pair microhomologous sequences to align the broken strands before joining.MMEJ ligates the DNA strands without checking for consistency and causes deletions since it removes base pairs (flaps) on the strand in order to align the two pieces.MMEJ repair of double-strand breaks (director's cut): deleted sequences and alternative endings.MMEJ uses a Ku protein and DNA-PK independent repair mechanism and repair occurs during the S phase of the cell cycle as opposed to the G0/G1 and early S phases in NHEJ and late S to G2 phase in HR.MMEJ works by ligating the mismatched hanging strands of DNA, removing overhanging nucleotides and filling in the missing base pairs.Microhomology-mediated End Joining (MMEJ) is one of the pathways for repairing double-strand breaks in DNA.Once aligned, any overhanging bases (flaps) and mismatched bases on the strands are removed and any missing nucleotides are inserted.Two other well known means of double-strand breakage repair are Non-homologous end joining (NHEJ) and Homologous recombination (HR).When a break occurs a homology of 5 - 25 complimentary base pairs on both strands is identified and used as a basis for which to align the strands with mismatched ends
