Answer : The length of protein will be, 36.8 A⁰
Explanation :
First we have to calculate the amino acid residue.
Given:
Length of single strand of protein = 27.0 kDa
Mean residue mass = 110 Da
Now we have to calculate the number of turns in protein.
As there are 3.6 amino acid per turn of the alpha-helix.
Now we have to calculate the length of the protein.
As, we know that the length of each turn = 0.54 A⁰
Thus, the length of protein will be, 36.8 A⁰
