Home » Bioinformatics » Bioinformatics Miscellaneous » Question

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
