3 Genes That Give People Superpowers

The video explores how certain DNA mutations can lead to superhuman traits, such as increased muscle mass, speed, and bone density. It discusses the role of specific genes like MSTN, ACTN3, and LRP5 in these processes. Myostatin mutations can lead to muscle hypertrophy, while ACTN3 mutations affect fast twitch muscle fibers, influencing speed. LRP5 mutations can result in denser bones. The video concludes by highlighting that everyone has mutations, though not all result in superpowers.

What is the role of myostatin in muscle development?

• It causes muscle cells to die quickly.

• It has no effect on muscle growth.

• It promotes muscle growth and division.

• It limits muscle growth and division.

Which gene is associated with fast-twitch muscle fibers?

• MSTN

• LRP5

• WINT

• ACTN3

What is the primary function of fast-twitch muscle fibers?

• To provide endurance for long-distance running.

• To enable quick bursts of speed and power.

• To stabilize slow-twitch muscle fibers.

• To store large amounts of glycogen.

What effect does a gain of function mutation in the LRP5 gene have?

• It causes bones to become brittle.

• It increases bone density.

• It has no effect on bone density.

• It decreases bone density.

What potential health issue can arise from excessive bone growth due to LRP5 mutations?

• Increased muscle weakness.

• Decreased muscle mass.

• Pressure on the brain or pinched nerves.

• Increased risk of fractures.
