Practice question
Question
A forty-times diluted sample of ssRNA gave an 𝐴 ₂₆₀ of 0.01. The concentration of the ssRNA before the dilution in μ𝑔/𝑚𝐿 was _____ (correct to the nearest integer). (NAT)
Explanation
Biologically, DNA replication fidelity operates via polymerase proofreading and origin firing ensure accurate duplication. Thus Option NAT is appropriate since it matches high-fidelity synthesis mechanisms, reinforcing core concepts taught in molecular biology.
