Solution
Chromosomes:
- Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.
- Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.
- Histone proteins are tightly coiled up inside the DNA as chromatin fibers, which further compact to create chromosomes.
- Condensed DNA is found in a tightly packed area of chromatin called heterochromatin. Its transcription is dormant.
- The transcriptionally active portion of chromatin is called euchromatin, which is loosely packed.
