SUMMARY

The discussion centers on the unique self-replicating properties of DNA and RNA compared to other macromolecules like proteins. It establishes that DNA requires proteins (enzymes) and RNA for replication, as proteins alone cannot catalyze the complex processes necessary for self-replication. The conversation highlights the electrostatic interactions that allow DNA molecules to fit together, akin to a zipper, facilitating the replication process. This mechanism is contrasted with simpler molecules, such as benzene, which lack the structural complexity required for self-replication.

PREREQUISITES
  • Understanding of DNA and RNA structures
  • Knowledge of enzymatic functions in biological processes
  • Familiarity with molecular interactions, particularly electrostatic interactions
  • Basic concepts of catalysis and self-replication
NEXT STEPS
  • Research the role of enzymes in DNA replication
  • Explore the mechanisms of RNA self-replication
  • Study the principles of molecular interactions in biochemistry
  • Investigate the limitations of protein catalysis in self-replication
USEFUL FOR

Biochemists, molecular biologists, and students interested in the mechanisms of genetic replication and the distinctions between different macromolecules.

Hi All

Why DNA molecules alone replicates itself were does self property of ( memory ) to replicate comes from ? why not other macro moloecules like proteins ( expect pirons :biggrin: ) don't replicate like DNA :confused:
 
Biology news on Phys.org
DNA does not replicate itself, it needs proteins (enzyme) and RNA. Proteins are excellent catalysts, but fail to catalyze processes complex enough to recreate themselves, individually. RNA is capable of both catalysis and self-replication.
 
why not applicable to simple micro molecules

:bugeye:

why not a simple benzene molecule can be catalysed and replicated why DNA /RNA alone have such property
 
Because DNA is like a zipper, two molecules through electrostatic interaction are able to fit perfectly into each other.. this property is used for the replication, you're building a new molecule from a template like lego.
