Sentences with phrase «longer size molecules»

Not exact matches

This effect, however, is small because the wavelength of light is much longer than the size of a molecule: the light's corkscrew is too big to sense the molecule's chiral structure efficiently.

By shining a laser light on a microscopic - sized plastic bead attached to a pair of microtubules linked by kinesin - 5 molecules, the team tracked their activity and discovered that this force is a function of the microtubule overlap — the longer the overlap, the greater the force.

«It's the first time a genome the size of a bacterium has chemically been synthesized that's about 20 times longer than [any DNA molecule] synthesized before,» adds Christopher Voigt, an assistant professor of bioengineering at the University of California, San Francisco, who was not involved in the study.

The researchers can then place virtual particles of food inside — each with its own physical properties — and simulate how long it takes for molecule - size nutrients to seep out.

Side chains are essentially small molecules of different shapes, sizes and chemical natures attached to the longer lipid - like peptoids.

The recently launched Gemcode system adds a new dimension to short - read DNA sequencing, by enabling the ordering of millions of barcoded short sequence reads of 150 base pairs into long continuous DNA molecules of hundreds of thousands of base pairs in size.

DNA sequencers can not sequence long pieces of DNA, so the extracted DNA molecules were sheared to different sized fragments in a controlled manner such that when they are sequenced they can be reassembled computationally by matching overlapping codes in the reads — creating long sequences of the genetic code.

Increasing the size of the actual protein molecules would theoretically take them longer to digest and could allow the anabolic whey aminos, including leucine, to release in a manner similar to casein.

Colloids often contain a mixture of molecule sizes, which keeps the fluids in the vascular space longer, but still have a relatively short half - life (25 hours according to the hetastarch package insert) and may require continuous infusion.

The process that I am focussing on is the preferential size - dependent fractionation of CO2 at a much later stage when the pores and channels are approaching the size of those different molecules, Fickian diffusion no longer applies and molecule kinetic rather than collision diameter must be taken into consideration.
