dna telomere repair

Dna exists as a double stranded structure with both strands coiled together to form the characteristic double helix each single strand of dna is a chain of four types of nucleotides nucleotides in dna contain a deoxyribose sugar a phosphate and a nucleobase the four types of nucleotide correspond to the four nucleobases adenine cytosine guanine and thymine commonly. Biology is brought to you with support from the amgen foundation. Non homologous end joining nhej is a pathway that repairs double strand breaks in dna nhej is referred to as non homologous because the break ends are directly ligated without the need for a homologous template in contrast to homology directed repair which requires a homologous sequence to guide repair the term non homologous end joining was coined in 1996 by moore and haber.
