In a few species, the origin is defined by a consensus sequence in the DNA. More commonly, origins are defined by general features of the sequence rather than a linear consensus, and are typically A/T rich and easily unwound. In some cases, origins appear to be distributed not by ...
Incorporation of metallo-base pairs intoDNAstructures has also attracted large attention as a promising approach to develop molecular devices. As discussed in Section “Discrete Self-Assembly of Homologous and Heterologous Metal Ions”, metallo-DNA structureshave great potential as templates for predesigned...
AncestryDNA tops the other DNA and genetic testing companies as the most accurate. Aside from providing in-depth ancestry research, they also have billions of records to compare their results. Are home DNA test kits accurate?+- Most DNA test kits are indeed accurate. Still, we suggest that ...
The oldest DNA ever analyzed shows that reindeer and mastodons once wandered a nearly unrecognizable Greenland.
·T base pairs in TAA·TTA tracts to adopt HG pairing. In summary, this study provides an example of a DNA functional element submitted to slow conformational exchange. More generally, it strengthens the importance of the role of the DNA sequence in modulating its dynamics, over a nano- to...
The ‘letters’ of DNA have another vital property due to their structure, which allows information to be transmitted: A pairs only with T, and C only with G, due to the chemical structures of the bases—the pair is like a rung or step on a spiral staircase. This means that the two...
Specialized DNA helicases efficiently unwind G-quadruplex (G4) DNA and other forms of alternative DNA structures such as telomeric displacement loops (T-loops). Emerging evidence suggests that DNA helicases that unwind non-conventional DNA structures have important roles in the replication or repair ...
si and ni indicate the number of deletion-supporting and non-supporting read pairs, respectively. Reads used for VAF calculation at breakpoint i were required to have read 1, containing the gene-specific primer, overlap the non-deleted region flanking breakpoint i. Reads were considered deletion...
More importantly, the design of PDI-arrays is critical for determination of specific sequences recognized by DNA-binding proteins. With this respect, two types of molecules have been used in PDI-arrays: short dsDNAs designed as self-complementary palindromes (Warren et al., 2006); and short ds...
