Answer:
No,The goal cannot be achieved
Explanation:
In calculating solid phase synthesis,
Yield(Y) = CE^n-1
CE is coupling efficiency
n is length of oligonucleotide
Therefore, according to the question
CE is 99%= 0.99(99/100)
n is 70
Y= 0.99^70-1= 0.99^69= 0.499
Converting to percentage
0.499 x 100=49.9% approximately 50%.
