  1. In an affine gap penalty model, if the gap opening penalty is -20, gap extension penalty is -4 and gap length is 8, the gap score is ___.
    1. - 30 to -5
    2. - 40 to -40
    3. - 52 to -52
    4. - 65 to -40
Correct Option: C

Gap score = 2 × Gap opening penalty + Gap extension penalty – Gap length
Here, Gap opening penalty = –20,
Gap extension penalty = –4 and gap length = 8
Therefore, Gap score = 2 × (–20) – 4 – 8 = – 52
