Each rung in the DNA ladder is called a base pair.

Number one is a standard DNA ladder, to help us estimate the relative positions for the various samples.

DNA ladders are often produced by a suitable restriction digest of a plasmid.

• Gene sequencing is a way to map all the genes on the DNA ladder.

However, when it is attached to a step on the DNA ladder, it is locked in shape.

It is clear, then, that the sequence of rungs on our DNA ladders represents an enormous library of information.

The 'rungs' of the DNA ladder are each made of two bases, one base coming from each leg.

Different DNA ladders are commercially available depending on expected DNA length.

It splices a copy of itself right into the genes of certain white blood cells, adding permanent new rungs to each cell's DNA ladder.

DNA gel electrophoresis of the neuroepithelial layer revealed a DNA ladder.

The Invitrogen 1 Kb Plus DNA ladder was used to provide a relative measure of length.

DNA ladders were produced again in these washed nuclei after reconstitution with the nuclear wash, which contained an endonucleolytic activity of approximately 97 kilodaltons.

Genetix's DNA ladders are high-quality ladders that give superior resolution in agarose gels.

A 1 kb 'DNA ladder' provides a 'molecular ruler' with fragments of known sizes against which the lambda fragments can be measured.

In humans, the DNA ladder consists of some three billion "rungs," or base pairs, that would stretch out nearly a meter (yard) in length if unfolded.

Initially, these fragments were visualized by conventional agarose gel electrophoresis as a DNA ladder consisting of multimers of approximately 200 base pairs.

A 'DNA ladder' is a solution of DNA molecules of different lengths used in agarose gel electrophoresis.

Fermentas is a producer of molecular biology products and is known for its restriction enzymes and DNA ladders and molecular weight markers.

A typical apoptotic DNA ladder and the cleavage of caspase-3 were observed after treatment with TGHS-1 and TGHS-2.

An extract is considered telomerase-positive if a DNA ladder of 6 bp periodicity is present and no corresponding signal is present in the heat-treated control (Fig. 1).

Taken together, these facts explain why DFF40/CAD generates sharper oligonucleosomal DNA ladders compared with those generated by MNase.

Base pairs form the "rungs" of the DNA ladder and the number of base pairs in a strand can be used to describe the length of DNA.

WASHINGTON - It has been a decade since the human genome was first sequenced and the 3.2 billion rungs of our DNA ladder laid out for analysis.

Following caspase 3-mediated cleavage, DFF45 releases DFF40, the DNase responsible for DNA fragmentation into the characteristic apoptotic DNA ladder.

DNA Ladders 100 bp and 1 Kb DNA ladders for Agarose Gel Electrophoresis.
