SUMMARY
This discussion identifies five key similarities between DNA and proteins, focusing on their structural and chemical properties. Both DNA and proteins are composed of smaller molecules that form chains; DNA is made of nucleotides while proteins are made of amino acids. The discussion highlights that both types of macromolecules involve specific reactions to join their monomers, such as peptide bonds for proteins and phosphodiester bonds for DNA. Additionally, the roles of side chains—R groups in proteins and nitrogenous bases in DNA—are emphasized as crucial components that influence their structure and function.
PREREQUISITES
- Understanding of molecular biology concepts, specifically nucleotides and amino acids.
