Four-stranded DNA discovered, linked to cancer

Recent research has identified the presence of four-stranded DNA in humans, known as the quadruple helix. This structure is often found just before cell division, suggesting a link to cancers that arise from increased DNA replication due to mutated genes. Understanding this connection may offer new insights into cancer treatment.

What is the traditional structure of DNA known as?

• Quadruple helix

• Single helix

• Double helix

• Triple helix

What recent discovery have researchers made about DNA in humans?

• A four-stranded DNA structure

• A new form of RNA

• A new type of protein

• A triple helix DNA

What is the four-stranded DNA structure called?

• Double helix

• Pentuple helix

• Triple helix

• Quadruple helix

When does the quadruple helix DNA most often appear?

• During cell death

• Before a cell divides

• During protein synthesis

• After cell division

How is the quadruple helix linked to cancer?

• It stops protein synthesis

• It is associated with mutated genes that increase DNA replication

• It reduces DNA replication

• It prevents cell division
