Answer:

The given statement is False.

Step-by-step explanation:

During the prophase stage of mitotis, the chromatin starts becoming more condense. Histone protein is a basic protein which is responsible for initial and basic packaging of chromatin into nucleosome.

The second level of chromatin packaging occurs when the nucleosomes are arranged in the fiber which has a diameter of about 30nm. Each nucleosome is attached with H1 histone and nucleosome fiber coil to form a solenoid structure which has a diameter of 30nm. Therefore the statement is false.
