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).
There are 3 main chemical components of DNA. They are phosphate, a sugar called deoxyribose and a nitrogenous base (adenine, thymine, cytosine or guanine). These three compone â¦ nts form a nucleotide.Deoxyribose contains 5 carbon atoms (1', 2', 3', 4', 5') in its structure.he three components that create a DNA nucleotide are a phosphate group, a nitrogenous base [this will be either Adenine, Guanine, Cytosine, or Thymine], and a Sugar [deoxyrib â¦ ose, which is how we get the D in DNA]. 5 people found this useful.
