Unwound protein and chromosome complexes inside the nucleus are called:
AChromatin
BCristae
CCentrioles
DConnexons
Answer & Solution
Correct answer: A. Chromatin
1. Chromosomes are not always in their tightly condensed form.
2. For most of the cell's life the DNA is unwound and bound to protein.
3. These unwound protein-chromosome complexes are called chromatin.
4. Chromatin describes that material both when condensed and when decondensed.
