a disagreement between the two DNA strands that the cell has to resolve by deciding which strand to replace. 会造成DNA双螺旋的不匹配,要解决这个问题,细胞需要决定替换哪一条链。 We realized that we could further engineer this three-part protein to flag the nonedited strand as the one to be ...
base pair- one of the pairs of chemical bases joined by hydrogen bonds that connect the complementary strands of a DNA molecule or of an RNA molecule that has two strands; the base pairs are adenine with thymine and guanine with cytosine in DNA and adenine with uracil and guanine with cytos...
Although considerable effort has been made to understand the functions of DNA helicases that are important for genomic stability and cellular homeostasis, the complexity of the DNA damage response leaves us with unanswered questions regarding how helicase-dependent DNA repair pathways are regulated and ...
The cascade of SDR reactions is very complicated and laborious, which has to screen the output DNA strands as the input of the next round of reaction. The proposed classifier could be implemented on a solid surface27 on which millions of samples can be organized according to their class labels...
In any organism in nature, genomic DNA is composed of two strands which in turn are composed of four deoxynucleotides bridged by a phosphodiesteric bond between the 5′-phosphate and the 3′-oxygen of two adjacent ribose moieties. From: Reference Module in Biomedical Sciences, 2017 ...
DNA ligases catalyze the formation of a phosphodiester bond between DNA single strands in the duplex form (Fig. 2.1). The covalent linkage of the 5′-P group of one chain with the adjacent 3′-OH group of another is coupled with the pyrophosphate hydrolysis of the cofactor ATP or NAD. Ba...
HOW IS STRAWBERRY DNA DIFFERENT FROM HUMAN DNA? Our cells have two copies of their DNA, while strawberry cells have eight! This makes it easier for us to extract enough DNA to see it with the naked eye. Every living thing has DNA, or deoxyribonucleic acid, which is the blueprint for wh...
Legacy Family Tree Webinars has just released DNA Academy. DNA Academy is a three-part series designed to introduce the basics of DNA for genetic genealogy and how Y-DNA, X-DNA, mitochondrial and autosomal DNA can be utilized. Each of these different types of DNA serves a different function...

A DNA repair pathway that repairs lesions where both DNA strands are broken. There are two major pathways of DSB repair; homologous recombination uses sister chromatid as a template for repair and non-homologous DNA end joining ligates the broken ends without regard for homology. Defects in DNA...
