Ladder Diagram Dna Base. For long term storage store at 20c. A ladder is a solution that contains a series of well defined dna fragments of particular lengths.
A molecule of dna consists of two strands that form a double helix structure. A t c c ga 10. Dna is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix.
The bases a g c g form the rungs of the ladder.
Chromatography purified dna fragments provide exceptional purity and quality. Ad choose from a wide range of sizes. Nucleotides the basic building block of dna is called a nucleotide. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings.
