The quality of blood samples affects the results of gene testing. How to prevent hemolysis? 確保基因檢測結果準確的關鍵是提供一個符合要求的合格樣本供實驗室化驗。 但在做DNA檢測時,血液樣本出現不合格(比如溶血)的情況並不少見。 樣本溶血會影響檢驗結果,由於要保證檢驗結果的真實性,因此對於溶血情況嚴重的...
These repeats are "regularly interspaced," meaning that these CRISPR regions in the genome contain an alternating pattern of palindromes with "spacer" sequences wedged between them. Bacteria co-opt the spacer sequences from theDNA of invading virusesand store them in their CRISPR regions to fight...
