types include: Shot noise; Johnson noise and Partition noise. In electrical terms, noise is defined as the unwanted form of energy which tends to interface with the proper reception and the reproduction of transmitted signals. Electronic Devices unwanted random addition to the signal are considered as Noise.
On the carbon labeled #1 on the deoxyribose sugar, you have the base added to it. These bases form the rungs of the DNA molecule. Adenine, Thymine, Cytosine and Guanine are the four possible bases. There are two different types of bases, purines and pyrimidines.They refer to the basic structure, or backbone if you will, of the bases.n the carbon labeled #1 on the deoxyribose sugar, you have the base added to it.

The reasoning behind the alternation of the sugar and phosphate molecules on a DNA ladder lies in the combination of bases to form the rungs of the ladder. The rungs are only between the sugar molecules. Two bases line up between these molecules and bond together, creating the rung appearance. There are no bases in between the phosphate molecules, thus there are no rungs between these molecules. There is open space that gives the DNA ladder the step appearance. The ladders of DNA that makeup the genes can be twisted or not twisted.
