Consider the following statements regarding euchromatin and heterochromatin: 1. Euchromatin is lightly packed, transcriptionally active, and stains lightly during interphase. 2. Heterochromatin is highly condensed, transcriptionally inactive, and replicates late in the S-phase of the cell cycle. 3. Constitutive heterochromatin can easily transition into euchromatin depending on the metabolic state of the cell. Which of the statements given above is/are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1 and 3 only
• D: 1, 2 and 3
