Nucleotides

Nucleotides

• A nucleotide is composed of a sugar molecule, a phosphate group, and a nitrogenous base (nucleobase)

Nucleic Acids

• DNA is responsible for storing genetic information in all life-forms on Earth
• RNA is also a type of nucleic acid, but it has a different role

Nucleobases

• The four nucleobases found in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T)
• Adenine, guanine, and cytosine are also found in RNA, but thymine is replaced by uracil (U) in RNA

Nucleotide Function

• Nucleotides play a crucial role in metabolism at a cellular level, serving as energy carriers, participating in signal transduction pathways, and acting as cofactors for enzymes

Nucleotide Synthesis

• Nucleotides are obtained from the body through de novo synthesis, which involves the formation of new nucleotides from precursor molecules, and salvage pathways, which involve the recycling of nucleotides from degraded DNA and RNA molecules
