CRISPR position nucleotides arranged special models were divided into two groups.The two areas.By the first nucleotide with short. A conservation area (conserve) with sequence repeatedly.Called direct repeat and found that the nucleotide sequence of the direct repeat is similar to a palindrome.It makes RNA line.From the area of the decoder direct repeat, can catch each other is on the secondary structure in the manner of a hairpin loop.The second is on nucleotide diversity (variable) with unique, unique, called spacer by spacer size estimation.Academic articles.Journal of agricultural science, over the years, 19 (No. 2) July - December 2557 156.24-28 base pairs are inserted between the direct repeat look like this, is repeat spacer - - repeat (picture 1) found that section.That is, spacer meal order the same nucleotide. The order of nucleotides some phages and plasmids and some kinds of bacteria.Then, always, or compromised before (Bolotin et al, 2005; Godde & Bickerton 2006), and found that the bacteria have mechanisms.Here, เอาชิ, the DNA some of the FA จห or plasmid in inserted in the direct repeat by Shi, two DNA import part here.Compared with a memory unit, (memory card) bacteria use the choir, types of FA from ever invaded. When the invasion.Of the FA จห or get back into the original plasmid type, mechanism of CRISPR will build the CRISPR - RNA (crRNA) out.Go, destroy the FA จห or plastic มิดนั, offer the specifications, which mechanism is similar to that found in the RNAi eukaryotic cells (Wiedenheft.Et al, 2012).Knowledge of CRISPR is still is a relatively new subject. Scientists understand the working of cases.CRISPR. Long problem. Current CRISPR is on one issue, scientists, lot of attention study.In order to understand its mechanism, to work harder, and find the application advantage of CRISPR in ความนี, have gathered.Knowledge area, based on such a matter and research approaches include, applied to a consistent approach for those interested.Study.
