What does “DNA structure” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
a double helix held by complementary base pairing: adenine with thymine, guanine with cytosine.
In simple words: a double helix held by complementary base pairing: adenine with thymine, guanine with cytosine. Getting DNA structure clear matters because NEET questions on Molecular Basis of Inheritance usually test this idea directly, not just a formula you memorised.
Key point
DNA structure
Common mistake
pairing adenine with guanine or cytosine.
Memory tip
A–T (2 hydrogen bonds), G–C (3 hydrogen bonds) — always.
