Question
Identify the diagram in which the nucleoplasm contains certain threadlike structures.
- Chromatic nerve
- Chromatin fiber
- Optic fiber
- Fiber threads
Hint:
Chromatin Fibers are Long and thin. They are uncoiled structures found inside the nucleus. Chromosomes are compact, thick, and ribbon-like. These are coiled structures seen prominently during cell division. Chromatin is unpaired.
The correct answer is: Chromatin fiber
- Chromosomes are condensed chromatin fibers.
- Chromatin is composed of nucleosomes, which are a complex of DNA and proteins.
- Chromosomes are thick, compact, and have a ribbon-like shape. Chromatin is a thin and long fiber. Distinctly visible during cell division.
