The Mechanism of DNA Replication

In summary, this study found that computer modeling is needed to understand the mechanism of DNA replication and protein synthesis, as this has not been seen in action. It is also interesting to note that the way DNA is damaged seems to cause it to become more flexible, which explains how the body's enzymes are able to fix it.

I once read a 1997 physics book. At the end of the 'static electricity' chapter, it explains the mechanism of DNA replication and protein synthesis (in which static electrical force plays a critical role). However, it says something like 'this model has not been seen in action. It is consistent by various experimental evidences and the current accepted physical theories.'

I'm curious about wether our 2004 technology is able to see this in action (in other words, have it been seen in action now)?

Thanks in advance.

Computer modeling may still be needed to answer questions in quantum chemistry

I don't think so, and the reason is that it has only been within the past week or so that researchers have known that DNA becomes more flexible when it is damaged and the way they found out is via computer modeling:


  • ...banged up DNA becomes flexible, suggests the most detailed computer model of damaged DNA to date. Further, this flexibility explains how the body's enzymes recognize and fix damaged DNA...

    Haranczyk said this was the first quantum chemistry simulation to survey such a large biological system--in this case, a DNA fragment made up of 350 atoms. "With a system so big, one can't do this kind of work without a supercomputer. Fortunately, we had access to one of the world's 10 most powerful computers,"

Thank you for sharing your knowledge about the mechanism of DNA replication and protein synthesis. It is fascinating to think that static electrical force plays a critical role in these processes. As for your question about whether this model has been seen in action with our current technology, I believe that there have been significant advancements in the field of genetics and molecular biology since 1997.

With the development of advanced imaging techniques, such as electron microscopy and fluorescence microscopy, scientists are now able to observe and study the process of DNA replication in real-time. These techniques have allowed us to visualize the various proteins and enzymes involved in DNA replication and see how they interact with each other.

Additionally, the use of genetic engineering and gene editing technologies, such as CRISPR-Cas9, has also provided valuable insights into the mechanisms of DNA replication and protein synthesis. By manipulating and altering specific genes, scientists have been able to confirm the role of certain proteins and enzymes in these processes.

While there may still be some aspects of the mechanism that have not been fully understood or observed, the advancements in technology have certainly allowed us to gain a better understanding of DNA replication and protein synthesis. I hope this answers your question and highlights the importance of continued research and technological advancements in this field.
 

Related to The Mechanism of DNA Replication

What is DNA replication?

DNA replication is the process by which a cell makes an exact copy of its DNA. This is an essential process for cell division and the passing of genetic information from parent to offspring.

Why is DNA replication important?

DNA replication is important because it allows for the accurate transmission of genetic information from one generation to the next. Without this process, cells would not be able to divide and organisms would not be able to reproduce.

How does DNA replication occur?

DNA replication occurs through a semi-conservative mechanism, meaning that each new DNA molecule formed is made up of one original strand and one newly synthesized strand. The process involves the unwinding of the DNA double helix, followed by the copying of each original strand by complementary base pairing.

What enzymes are involved in DNA replication?

The main enzymes involved in DNA replication are DNA polymerase, which adds new nucleotides to the growing DNA strand, and DNA helicase, which unwinds the DNA double helix. Other enzymes, such as primase and ligase, also play important roles in the process.

What is the role of DNA replication in cell division?

DNA replication is essential for cell division as it ensures that each daughter cell receives an exact copy of the genetic information from the parent cell. This allows for the production of new cells with the same genetic makeup and function as the original cell.
