What does “DNA double helix” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
two antiparallel strands held together by complementary base pairs, A with T and G with C.
In simple words: two antiparallel strands held together by complementary base pairs, A with T and G with C. Getting DNA double helix clear matters because NEET questions on Molecular Basis of Inheritance usually test this idea directly, not just a formula you memorised.
Key point
DNA double helix
Common mistake
pairing adenine with guanine or cytosine.
Memory tip
A-T has two hydrogen bonds, G-C has three -- so G-C rich DNA is more stable.
