What does “Semiconservative replication” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
each new DNA molecule keeps one old (parental) strand and one newly made strand.
In simple words: each new DNA molecule keeps one old (parental) strand and one newly made strand. Getting Semiconservative replication clear matters because NEET questions on Molecular Basis of Inheritance usually test this idea directly, not just a formula you memorised.
Key point
Semiconservative replication
Common mistake
thinking both strands of a daughter molecule are freshly synthesised.
Memory tip
'semi' means half-old, half-new in every daughter helix (Meselson-Stahl).
