Question

The distribution of melanosomes in cells is tightly regulated in animals that rapidly change color. Dark-colored cells have melanosomes scattered throughout the cytoplasm while light-colored cells have them aggregated near the nucleus. How could cells use microtubules and motor proteins to change the distribution of melanosomes

1. The melanosomes move along microtubule tracks using motor proteins.2. Kinesin would be responsible for moving melanosomes outward to generate dark-colored cells.3. Dynein would be used for moving melanosomes back to the nucleus in light-colored cells.4. Microtubules originate near the nucleus of animal cells, and the positive ends project outward.

Answer 1

Answer: 4, 3, 2, 1

Step-by-step explanation:

Microtubules originate near the nucleus of animal cells, and the positive ends project outward.

Dynein would be used for moving melanosomes back to the nucleus in light-colored cells.

Kinesin would be responsible for moving melanosomes outward to generate dark-colored cells.

The melanosomes move along microtubule tracks using motor proteins.
