Answer : The length of protein will be, 96.8 A⁰

Explanation :

First we have to calculate the amino acid residue.

$\text{Amino acid residue}=\frac{\text{Length of single strand of protein}}{\text{Mean residue mass}}$

Given:

Length of single strand of protein = 71.0 kDa

Mean residue mass = 110 Da

$\text{Amino acid residue}=\frac{71.0kDa}{110Da}=\frac{71000Da}{110Da}=645.4$

Now we have to calculate the number of turns in protein.

$\text{Number of turns in protein}=\frac{\text{Amino acid residue}}{3.6\text{amino acid per turn of the alpha-helix}}$

As there are 3.6 amino acid per turn of the alpha-helix.

$\text{Number of turns in protein}=\frac{645.4}{3.6}=179.28$

Now we have to calculate the length of the protein.

$\text{Length of protein}=\text{Number of turns in protein}\times \text{Length of each turn}$

As, we know that the length of each turn = 0.54 A⁰

$\text{Length of protein}=179.28turns\times \0.54\AA=96.8\AA$

Thus, the length of protein will be, 96.8 A⁰
