Not many people get organic substances in pure form (or in the form of homogeneous mixtures) are already in antiquity. Fats and oils, no doubt, are among their number. Therefore, their names are in all languages simple native, although the chemists call them also lipids (from the Greek "liposome" - fat). To detect them was easy because they occur in all living organisms, and often in large numbers. Nature took care of animals and plants, providing them with supplies of fuel for cold and hungry days. Animals put this fuel, mainly around the internal organs and under the skin to fat deposits at the same time served as a shock-absorbing cushion shocks and heat insulator. Other

How to see DNA
Heredity, genes, DNA ... It seems that these words have long ceased to be scientific terms, entered into everyday life and is now familiar to every senior, not to mention the students. But there was no DNA, most of us have never seen, though to see it - it is quite real, even in the home. In one of the genetic laboratory on the wall, for example, that the instruction:
- Find something that contains a lot of DNA. For example, green peas (but may be chicken liver, herring roe, or onion).
- Put in a blender about 100 ml (half a cup) of this product, add 1 / 8 teaspoon of salt and 200 ml (cup) of cold water. Whips within 15 seconds. Mixer «cook» you pea-cell soup.

The First Effective Whole Genome Amplification
Unlimited DNA from a few cells.
The
growing trend to study disease and drug response at the molecular level
has focused attention on DNA as a precious resource. Multiple Displacement
Amplification (MDA) technology developed by MSI enables the first effective
whole genome amplification method. The MDA method is a quantum leap over
other currently available whole genome amplification methods, which are
based on PCR
The MSI MDA method rapidly amplifies the genome with comprehensive loci
coverage and minimal bias between any loci, yielding 10+kb fragments in
a simple, scalable reaction.

DNA at end of reaction.
Most amplified strands are converted to double-stranded DNA at end of reaction.
stranded template for on-going priming
After initial priming, an exponential cascade of branched amplification generates single-stranded template for on-going priming.
