High throughput sequencing offers many advantages over dna microarrays. Endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain. Despite these advantages dna has not yet become a widespread information storage medium because the cost of.

In particular it is more precise and not subject to cross hybridization thereby providing higher accuracy and a larger dynamic range 10 5 for dna sequencing vs 10 2 for dna microarrays wang et al 2009. Pyrimidine dimers introduce local conformational changes in the dna structure which allow recognition of the lesion by repair enzymes. Endonucleases differ from exonucleases which cleave the ends of.

Dna sequencing is the process of determining the exact sequence of nucleotides within a dna molecule.

Dna 量. Similar to microarrays however hts based applications can be. This means that by sequencing a stretch of dna it will be possible to know the order in which the four nucleotide bases adenine guanine cytosine and thymine occur within that nucleic acid molecule. In most organisms excluding placental mammals such as humans they can be repaired by photoreactivation. Photoreactivation is a repair process in which photolyase enzymes directly reverse cpds via photochemical reactions.

In addition dna s four letter nucleotide code offers a suitable coding environment that can be leveraged like the binary digital code used by computers and other electronic devices to represent any letter digit or other character. Some such as deoxyribonuclease i cut dna relatively nonspecifically without regard to sequence while many typically called restriction endonucleases or restriction enzymes cleave only at very specific nucleotide sequences.
