A mutation refers to a change in the DNA sequence. This means that the original sequence of bases in the DNA has been altered permanently.
There are three types of DNA mutations; base substitutions, deletions and insertions.

A scalene
Explanation;
A triangle is a geometric figure with three sides and three angles that always add up to 180 degrees.
Based on properties triangles can be classified as equilateral, scalene, isosceles and right triangles.
Equilateral triangles has all the three sides and the angles equal, an isosceles triangle has two of its sides equal, and two angles that are known as the base angles equal. A scalene triangle has all the three angles and sides different from each other. A right triangle is a triangle in which one of the angle is right angle or is 90 degrees.
An isosceles triangle may be a right triangle, equilateral triangle, and also may be an acute triangle, however an isosceles triangle can never be a scalene triangle
