The structures that appear as “Beads-on-string” in the chromatin and the number of base pairs are
Show Hint
Each nucleosome core wraps ~200 base pairs of DNA and gives chromatin its “beads-on-string” appearance.
Updated On: Mar 19, 2026
- Nucleotides, 100
- Genes, 200
- Kinetochore, 100
- Nucleosome, 200
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Nucleosomes are the repeating units of chromatin that appear as "beads-on-string" under an electron microscope. Each nucleosome contains about 200 base pairs of DNA wrapped around histone proteins.
