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).
Nucleotides contain: 1. They consist of a pentose sugar, a phosphate molecule, and a nitrogen-containing base. The kind of sugars that nucleotides contain is the five carbon ring structure. A nucleotide is an organic molecule made up of a sugar, a  phosphate, and a nucleotide base. It is the basic unit of DNA and  RNA. A nucleotide does not contain an amino aciâ¦d.
