If the forward current through the diode is near the maximum the diode is designed for, it typically has an RF resistance of only 0.1 ohm, and thus acts as a closed switch. Thus, for RF, the PIN diode acts as a closed switch if it is forward biased with the near maximum DC bias current.
A nucleotide is a chemical compound with three components: a nitrogen-containing base, a pentose (five-carbon) sugar (relatively simple carbohydrates), and one or more phosphate groups.he nitrogen-containing base of a nucleotide (also called the nucleobase) is typically a derivative of either purine or pyrimidine, which are heterocyclic compounds (organic compounds that contain a ring structure that has, in addition to carbon, such atoms as sulfur, oxygen, or nitrogen).
The three major components in each strand is Deoxyribose, a sugar (notably lacking an oxygen compared to Ribose, which is found in RNA), a phosphate group, and a nucleotide: in the case of DNA, either Adenine, Cytosine, Guanine, or Thymine.ach DNA molecule is made of a string of nucleotides. Each nucleotide consists of a deoxyribose (pentose) sugar, a phosphate group, and a nitrogenous base (which can either be A, T, C, or G). sctan Â· 6 years ago. Thumbs up.
