<u>There are several problems posed by chromatin during transcription:</u>
- During transcription, protein can interfere with the chromatin structure at specific locations and interefere with its structure.
- Histone post-translation modifications (PTMs) regulate the structure of chromatin and also guide the remodeling enzymes which use the energy derived from ATP hydrolysis to reposition nucleosomes.
- During replication the chromatin structure rearrange itself in order to make the new DNA fit inside the nucleus.
Hence, the correct option is d.
