Four-Stranded DNA





The double helix DNA structure has been known to hold the chemical code for all life. Recent studies have found that this is not entirely true. Scientist have found four-stranded DNA in human cells. High concentration of quadruplexes have been linked with DNA replication errors such as cancer. Scientist have found a way to stop the quadruplexes from dividing. Therefore, this may be an exciting new way to prevent cancer cells from spreading. However, the four-strand helix is still new information. Scientist are not sure if the quadruplexes have a purpose or if it’s made completely by accident. We still need to do a lot more experiments before anyone can consider using this information to help cancer patients.

The double helix DNA has been engraved into my head so badly that I didn’t even consider that there may be variations to DNA structure. If the quadruplexes do play a big role in cancer development, we may have just discovered a way to attack tumors at their root. We may be years away before we can use this information to our advantage. Also, I don’t believe this may be the final step in curing cancer, but I do think that this may be one more step in the right direction.
