While replicating DNA, the rate of mis-incorporation by DNA polymerase is 1 in 105 nucleotides. However, the actual error rate in the replicated DNA is 1 in 109nucleotides incorporated. This […]

Although ribonucleoside triphosphates (rNTPs) are present at approximately IO-fold higher concentration than deoxyribo-nucleoside triphosphates (dNTPs) in the cell but they are incorporated into DNA at a rate that is more […]
