Question

Which of the following dimensions in chromatin packing is INCORRECT?

A) 30-nm fiber
B) Solenoid
C) Histone octamer
D) 10-nm fiber

Answer 1

The incorrect dimension in chromatin packing is the 10-nm fiber. DNA is wrapped around histone proteins to form nucleosomes, which are then further compacted into a 30-nm fiber.

Step-by-step explanation:

The incorrect dimension in chromatin packing is the 10-nm fiber. In eukaryotic cells, DNA is wrapped around histone proteins to form structures called nucleosomes. The DNA-histone complex is then further compacted into a 30-nm fiber. The other dimensions mentioned in the options (30-nm fiber, solenoid, histone octamer) are all correct.
