Question

(a) How does mutation occur?
(b) Differentiate between point mutation and frameshift mutation.

Answer 1

Answer:

a: Volcanic mountains are formed when a tectonic plate is pushed beneath another (or above a mid-ocean ridge or hotspot) where magma is forced to the surface. When the magma reaches the surface, it often builds a volcanic mountain, such as s shield volcano or a stratovolcano.

b: Mountain bikes are designed to conquer off-road terrain like dirt, mud, snow and gravel. These bikes are built especially tough, with thick tires and strong wheels that resist damage from impact. The frames are made from aluminum, carbon fiber, steel and titanium, and are built to withstand a lot of punishment.

Spontaneous mutations are the result of errors in natural biological processes, while induced mutations are due to agents in the environment that cause changes in DNA structure.
