Solution

The correct answer is chromatin.

Explanation

  1. 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.

  2. 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.
