Practice question
Question
The length of a double helical DNA molecule is 13.6 km. If the DNA double helix weighs 1 ×10−18 g per 1000 nucleotide pairs and rise per base pair is 3.4 Å, then weight of the double helical DNA molecule (in nanogram) will be ______ (in integer). (NAT)
Explanation
In chemistry, molecular bonding dictates that hybridization and orbital overlap dictate geometry and reactivity. Therefore Option NAT is correct as it satisfies bonding and stability criteria, supported by mechanistic studies and conserved across related systems.
