웹2024년 1월 17일 · Such a distance is anticipated for a 12 base pair separation of a typical B-DNA and agrees well with a 2.25 μs molecular dynamics (MD) simulation of five averaged 450 ns replicates. The DEER time trace of the 2 : 1 protein to DNA sample is distinctly different compared to the free DNA, which clearly indicates a different conformational ensemble for … A base pair (bp) is a fundamental ... On the converse, regions of a genome that need to separate frequently — for example, the promoter regions for often-transcribed genes — are comparatively GC-poor (for example, see TATA box). GC content and melting temperature must also be taken into account when … 더 보기 A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the … 더 보기 Hydrogen bonding is the chemical interaction that underlies the base-pairing rules described above.
