    Mystery
In summary, DNA molecules do not replicate themselves. They require the help of proteins and RNA, as proteins are not capable of catalyzing complex enough processes to recreate themselves individually. RNA, on the other hand, can both catalyze and self-replicate. This process is not applicable to simple micro molecules like benzene, as DNA and RNA have a unique property of electrostatic interaction that allows them to perfectly fit together and replicate like a zipper.

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:

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.
 

1. What is DNA self-replication?

DNA self-replication is the process by which DNA makes copies of itself. This is essential for cell division and the passing of genetic information from parent to offspring.

2. How does DNA self-replication occur?

DNA self-replication occurs through a process called DNA replication. During this process, the two strands of DNA separate and each strand serves as a template for the creation of a new complementary strand. This results in two identical DNA molecules.

3. What is the significance of DNA self-replication?

DNA self-replication is crucial for the survival and reproduction of organisms. It allows for the passing of genetic information from parent to offspring, which is essential for maintaining the genetic diversity and functioning of species.

4. Can DNA self-replication go wrong?

Yes, DNA self-replication can go wrong. Errors can occur during the DNA replication process, resulting in mutations or changes in the genetic code. These mutations can have harmful or beneficial effects on an organism's traits and may play a role in evolution.

5. How has our understanding of DNA self-replication evolved over time?

Our understanding of DNA self-replication has evolved significantly since its discovery in 1953. Scientists have conducted numerous experiments and studies to unravel the complex mechanisms involved in DNA replication. This has led to breakthroughs in genetic engineering, medical treatments, and other fields reliant on a deep understanding of DNA self-replication.
