Solution(By Examveda Team)

Nonhistone proteins present over chromosomes are DNA polymerase and RNA polymerase.
The non-histone proteins are a large group of heterogeneous proteins that play a role in organization and compaction of the chromosome into higher-order structures.
Scaffold proteins, DNA polymerase, RNA polymerase Heterochromatin Protein 1 and Polycomb are common non-histone proteins.
