This enzyme work well at A↓pN, T ↓pN sites, and especially A↓pN sites are 100% degraded. However, it is difficult to degrade C↓pC, C↓pG site. Mung bean exonuclease is a nuclease derived from mung beans that removes nucleotides in a step-wise manner from single stranded DNA molecules and is used to remove such ssDNA from a mixture also ...
Nucleic acid thermodynamics is the study of how temperature affects the nucleic acid structure of double-stranded DNA (dsDNA). The melting temperature (T m) is defined as the temperature at which half of the DNA strands are in the random coil or single-stranded (ssDNA) state. T m depends on the length of the DNA molecule and its specific ...
Differences in relative abundance of transcripts are highlighted, as are genetic differences between species. The technique relies on the removal of dsDNA formed by hybridization between a control and test sample, thus eliminating cDNAs or gDNAs of similar abundance, and retaining differentially expressed, or variable in sequence, transcripts ...
Between those two rings of RuvB, two sets of the RuvA protein assemble in the center of the Holliday junction such that the DNA at the junction is sandwiched between each set of RuvA. The strands of both DNA duplexes—the "donor" and the "recipient" duplexes—are unwound on the surface of RuvA as they are guided by the protein from one duplex ...
Restriction endonucleases may be found that cleave standard dsDNA (double-stranded DNA), or ssDNA (single-stranded DNA), or even RNA. [citation needed] This discussion is restricted to dsDNA; however, the discussion can be extended to the following: Standard dsDNA; Non-standard DNA; Holliday junctions
At a wavelength of 260 nm, the average extinction coefficient for double-stranded DNA (dsDNA) is 0.020 (μg/mL) −1 cm −1, for single-stranded DNA (ssDNA) it is 0.027 (μg/mL) −1 cm −1, for single-stranded RNA (ssRNA) it is 0.025 (μg/mL) −1 cm −1 and for short single-stranded oligonucleotides it is dependent on the length and base ...
Rolling circle replication produces multiple copies of a single circular template. Rolling circle replication (RCR) is a process of unidirectional nucleic acid replication that can rapidly synthesize multiple copies of circular molecules of DNA or RNA, such as plasmids, the genomes of bacteriophages, and the circular RNA genome of viroids.
DNA end resection, also called 5′–3′ degradation, is a biochemical process where the blunt end of a section of double-stranded DNA (dsDNA) is modified by cutting away some nucleotides from the 5' end to produce a 3' single-stranded sequence.
