each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this pattern of bonding looks much like a ladder with ...

Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a ...

What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and ...

By using epigenetic modifications, you can quickly write data in parallel without needing to synthesize new DNA.

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...

DNA polymerase enzymes use the existing DNA strand as a template and add the complementary nucleotides, including thymine, to the growing new strand. Mutations involving thymine can occur during DNA ...

Testing your DNA is easier than ever with an abundance of at-home DNA tests on the market. All you need to do is provide a simple DNA sample to learn more about your heritage and family history.

The hypothetical particle that mediates gravity, the “graviton”, would be described in this framework as an entity with “spin 2”, meaning it has a double spin that resembles the double helix of DNA.

Encoding information in DNA has long seemed like a promising way to secure data for the long term, but so far it has required an expert touch.

The DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks into phosphodiester ...

Tiny circles called ecDNA are critical in cancer development and drug resistance. An international team publishes landmark studies detailing new findings and potential therapies.

How Do At-Home DNA Kits Work? Most at-home DNA testing kits use saliva and provide a collection kit. Once you send your collection kit back to the company, they will likely either send it to a ...
