I f you need to know the exact times that the markets open and close, you have to take time zones into consideration. It is very simple when expressed in GMT. This is Greenwich Mean Time. This is the standard (winter) time in Greenwich, London which is the point of zero longitude on the globe. The normal Forex market hours are 22.00 Sunday GMT to 22.00 Friday GMT.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.The DNA double helix showing base pairs. The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.There are four types of base: adenine (A), thymine (T), guanine (G) and cytosine (C). These bases link in a very specific way: A always pairs with T, and C always pairs with G. The DNA molecule has two important properties.he rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.

The DNA molecule has two important properties.
Base pairs on a DNA molecule. If A occurs in one strand of a DNA molecule it will form a bond with T in the other strand. C and G will also only bond with each other. In this way it's possible to predict the order of bases on the other strand if the bases on one strand are known.NA is a long molecule made up of twisted strands of the bases A, T, C and G. Genes are sections of the DNA and each gene has the code for creating a specific protein. The sequence of bases in the gene controls which amino acids are created and joined to make a specific new protein or enzyme molecule.
