Nucleotides and nucleic acids

Nucleotides and nucleic acids

1. A nucleotides are monometers of nucleic acid chains and fall into two general classes

   • Deoxyribose nuclotides
   • Ribose nucleotides

2. All nucleotides are made of three parts

   • Phosphate group
   • Five-carbon sugar
   • Nitogen-containing base

3. Nucelotides act as energy carries and intracellular messagers.

   • Adenosine triposphate (ATP) is deoxyribose nucleotide with three phosphate functional group.
   • Ribose nucelotide cyclic adensoine monophosphate (cAMP) acts as a messeger molecule in cell.
   • Electron carries are those nucleotides (NAD and FAD) transporting energy in the form of high-energy electrons.

4. DNA and RNA the molecules of heredity are nucleic acids.

   • DNA is found in chromosomes and carries genetic information needed for protein construction.
   • RNA makes copies of DNA and is used direclty in the synthesis of proteins.
