New DNA structure found

The video discusses a new DNA structure called the i-motif, detailed in Nature Chemistry. Unlike normal DNA, where cytosine pairs with guanine, the i-motif structure features cytosine pairing with cytosine. This discovery may play a role in DNA reading and the synthesis of useful substances, as reported by The Independent.

What is the name of the new DNA structure discussed in the video?

• Z-DNA

• Quadruplex

• Triple helix

• i-motif

Which of the following bases are part of normal DNA?

• Thymine, Uracil, Cytosine, Guanine

• Adenine, Thymine, Cytosine, Guanine

• Adenine, Uracil, Cytosine, Guanine

• Adenine, Thymine, Uracil, Guanine

In normal DNA, which base does cytosine typically pair with?

• Adenine

• Thymine

• Guanine

• Cytosine

In the i-motif structure, which base does cytosine pair with?

• Cytosine

• Adenine

• Thymine

• Guanine

What potential role does the i-motif structure play in DNA function?

• Transcription of RNA

• Replication of DNA

• Repair of DNA

• Reading DNA and converting it into useful substances
