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 are molecules consists of three parts-a nitrogen base, a five-carbon sugar and a phosphate group. DNA and RNA are made of the subunits called nucleotides. 3 people found this useful.ach nucleotide is composed of a sugar + a phosphate + a nitrogen base. The nitrogenous bases are Adenine which pairs with Thymine and Cytosine which pairs with Guanine.
