They are also both electrolytes, involved in conducting electricity throughout the body, affecting nerve function, muscle contraction and the rhythm of the heart.Potassium and magnesium are found in many foods, and meeting your daily requirements for each mineral is not difficult.hey are also both electrolytes, involved in conducting electricity throughout the body, affecting nerve function, muscle contraction and the rhythm of the heart.

What are the four types of nucleotides? The four types of nucelotides are Thymine, Guanine, Cytosine, and Adenine. For RNA, Adenine is replaced with Uracil, which is a smaller nucleotide of sorts. The four nucleotidâ¦es pair as Thymine and Adenine (or Uracil in RNA), and Guanine or Cytosine.
Nucleotides are the building blocks of nucleic acids, the information carrying macromolecules of the cell. The two types of nucleic acids are ribonucleic acid, called RNA, and deoxyribonucleic acid, called DNA.Nucleotides consist of three parts (see Figure, p. 87- p. 85, 3E): 1) a sugar (either ribose (in RNA only) or 2-deoxyribose (in DNA only)).2) a nitrogen base (a purine or pyrimidine ring) attached to the sugar 1' carbon.3) a phosphate group or groups, usually attached to the sugar 5' carbon.ucleotides are the building blocks of nucleic acids, the information carrying macromolecules of the cell.
