The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs ...
Double stranded DNA that enters from the front of the enzyme is unzipped to avail the template strand for RNA synthesis. For every DNA base pair separated by the advancing polymerase, one hybrid RNA:DNA base pair is immediately formed. DNA strands and nascent RNA chain exit from separate channels; the two DNA strands reunite at the trailing end ...
3: chromEnd: End coordinate on the chromosome or scaffold for the sequence considered. This position is non-inclusive, unlike chromStart (the first base on the chromosome is numbered 1 i.e. the number is one-based). Yes 4: name: Name of the line in the BED file No 5: score: Score between 0 and 1000 No 6: strand
DNA is read by DNA polymerase in the 3′ to 5′ direction, meaning the new strand is synthesized in the 5' to 3' direction. Since the leading and lagging strand templates are oriented in opposite directions at the replication fork, a major issue is how to achieve synthesis of new lagging strand DNA, whose direction of synthesis is opposite to ...

The possible letters are A, C, G, and T, representing the four nucleotide bases of a DNA strand – adenine, cytosine, guanine, thymine – covalently linked to a phosphodiester backbone. In the typical case, the sequences are printed abutting one another without gaps, as in the sequence AAAGTCTGAC, read left to right in the 5' to 3' direction.
A DNA unwinding element (DUE or DNAUE) is the initiation site for the opening of the double helix structure of the DNA at the origin of replication for DNA synthesis. [1] It is A-T rich and denatures easily due to its low helical stability, [ 2 ] which allows the single-strand region to be recognized by origin recognition complex .
The Analysis page allows users to analyze the thermodynamic properties of a dilute solution of interacting nucleic acid strands in the absence of pseudoknots (e.g., a test tube of DNA or RNA strand species). [1] [3] For a dilute solution containing multiple strand species interacting to form multiple species of ordered complexes, NUPACK ...
