Question
Together, the entire complex of DNA and all of its associated proteins is referred to as _____.
Group of answer choices
- chromatin
- heterochromatin
- genome
- chromosomes
Solution
The correct answer is chromatin.
Explanation
-
Chromatin is the term used to describe the entire complex of DNA and its associated proteins within the nucleus of eukaryotic cells. It exists in a less condensed form during the interphase of the cell cycle, allowing for processes such as transcription and DNA replication.
-
The other options:
- Heterochromatin refers to tightly packed forms of DNA, which are generally not active in transcription.
- Genome typically refers to the complete set of genes or genetic material present in a cell or organism but does not include the protein components.
- Chromosomes are structures of DNA and protein that become visible during cell division but are not the term used when referring to the entire DNA-protein complex in the interphase.
Thus, chromatin is the most appropriate choice to describe the entire complex of DNA and associated proteins.
