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. Appropriate geometrical … 더 보기 Mismatched base pairs can be generated by errors of DNA replication and as intermediates during homologous recombination. … 더 보기 An unnatural base pair (UBP) is a designed subunit (or nucleobase) of DNA which is created in a laboratory and does not occur in nature. DNA sequences have been described which … 더 보기 Chemical analogs of nucleotides can take the place of proper nucleotides and establish non-canonical base-pairing, leading to errors (mostly point mutations) in DNA replication 더 보기 The following abbreviations are commonly used to describe the length of a D/RNA molecule: • bp = base pair—one bp corresponds to approximately 3.4 더 보기 In addition to the canonical pairing, some conditions can also favour base-pairing with alternative base orientation, and number and geometry of hydrogen bonds. These pairings are … 더 보기 웹2004년 5월 3일 · If the helicase does not lower the energy barrier of base pair separation, the mechanism is classified as passive. The rate of spontaneous base pair opening is fast ( 17 ) and it has been shown that a 5-bp hairpin loop can open at rates >3,000 s -1 ( 18 ), which exceeds the rate of translocation and unwinding by any helicase ( 19 - 24 ).

웹Polyacrylamide gel electrophoresis provides very high resolution of DNA molecules 10–3,000 bp long. Under the appropriate conditions, DNA molecules differing in size by only a single … 웹Watson and Crick stated that “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.” As predicted, the two DNA strands are separated during DNA replication and each parental strand serves as a template for the synthesis of a new, complimentary daughter strand … characteristics of covalent network solids
