Answer: Mutation
Explanation: Mutation is a change in DNA sequence, it may occur due to error when the DNA is copied or it can arise from various environmental factors such as exposure to chemicals, UV radiation, Highly infectious microbes.
Mutation maybe spontaneous. Acquired mutations occur at some point in a person's life and are present only in certain cells, not in every cell in the body while some may target a tissue, an organ or an entire system.

- Fasten around the waist and neck.
STEP 2: SHOE COVERS
- Layer shoes with shoe covers on top.
STEP 3: GLOVES
- Apply the first set of gloves and inspect them for tears.
- Thumb hole made in lab coat
- Thumb through opening in lab coat after pulling it over the hand
- Put on a second set of gloves (extend to cover wrist)
STEP 4: MASK OR RESPIRATOR
- As you cup the respirator in your hands, place the nosepiece there.
- With the nosepiece up, place the respirator under your chin. Pull the top strap over your head, putting it at the back of your head.
- Pull the bottom strap so that it is around your neck and just behind your ears.
- Mold the nose using two hands.
- Put both hands over the mask and take a forceful breath out.
- If air leaks, adjust the mask.
STEP 5: GOGGLES OR FACE SHIELD
- Put over face and eyes, then make adjustments to fit
