interlocked DNA necklace

Interlocked DNA necklace | gold vermeil

The same 36 mm interlocked-helix structure, rendered in 18K gold vermeil. Two DNA molecules threaded through one another, holding the geometry of a process that cells solve and re-solve through every division. Worn most often by people who have spent enough time with DNA to know the helix is rarely on its own.

The Science Behind Interlocked DNA

Two DNA duplexes can become physically linked during recombination, where four-stranded intermediates known as Holliday junctions form between homologous chromosomes. Robin Holliday inferred their existence in 1964 from genetic data in fungi, and electron microscopy confirmed the structure in the 1970s. Resolution of these junctions, by enzymes such as RuvC in bacteria or GEN1 in mammalian cells, is what shuffles genetic material between maternal and paternal chromosomes during meiosis. Without this routine interlocking and resolution, recombination would not work, and the genetic diversity that drives evolution and underpins immunity would not exist.

A Quiet Symbol For

Researchers and clinicians whose work touches DNA repair, recombination, or chromosome biology.

• geneticists and molecular biologists working on recombination or DNA repair
• medical oncologists and radiation oncologists familiar with DNA-damage response
• cell biologists who study mitosis, meiosis, or chromosome dynamics
• structural biologists who think about DNA as a three-dimensional object

Buyers split into two groups: scientists who want the recombination geometry on their lapel for a conference, and gift-givers marking a defended thesis or a first-author paper.

Frequently Asked Questions

What does the interlocked geometry represent?

Two DNA molecules in physical contact. That state arises during recombination, where homologous chromosomes exchange segments through Holliday junctions, and after replication, where daughter chromosomes are catenated until topoisomerase enzymes unlink them.

Is this the same molecule as the standard DNA necklace?

The base structure is the same double helix, but the geometry is different. A single DNA pendant shows the molecule. The interlocked version shows two molecules in the act of interacting.

What are the specs and what is the return policy?

18K gold vermeil with sterling silver core and 2.5 micron gold plating, 36 mm pendant, 45 cm chain with a 5 cm extender. Nickel-free and hypoallergenic. Ships free worldwide via DHL Express in 1-5 business days, with all import duties and taxes covered. 30-day “Love It or Return It” returns.

Is this also available in silver?

Yes. The same 36 mm interlocked DNA pendant is available in 925 sterling silver at the same size and chain length.
