Answer: 55 residues

Step-by-step explanation:

We are given that length of sheet= 193 Å

We need to find out the number of residues in this segment.

Now in an anti parallel β sheet, the repeat comes out after every 7Å.

In every repeat, there are 2 residues.

So, to find out the number of residues in segment, we multiply the number of segments with the residues in every segment.

Residues in segment= $\frac{193}{7}*2\\$

Residues in segment= 55.14

Or 55 residues.
