What is the structure formed by the bonding of nucleotides in DNA?

• A. Triple helix
• B. Double helix
• C. Linear chain
• D. Single strand

Answer: (B)

The structure formed by the bonding of nucleotides in DNA is the double helix. This refers to the iconic shape of DNA, where two long strands of nucleotides twist around each other, resembling a spiral staircase. Each strand is composed of a sugar-phosphate backbone and nitrogenous bases that pair specifically (adenine with thymine and cytosine with guanine) through hydrogen bonds, contributing to the stability and functionality of the molecule. The double helix structure is crucial for the processes of replication and transcription in genetics, as it allows the strands to separate and serve as templates for copying genetic information. This unique shape not only protects the genetic data but also enables efficient packing of DNA within the cell nucleus.
