WebMutations can occur in two ways: spontaneously or by agents known as mutagens. Spontaneous, or random, mutations occur because molecules are constantly moving inside a cell, which can cause collisions. These collisions can cause interruptions in DNA replication which can result in damage of DNA information. WebMutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. Often …
