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