Which one of the following options represents the correct response of the nucleus and the chromatin to a gradual increase in salt concentrations under standard experimental conditions?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1The nucleus bursts at low NaCl concentrations, liberating the chromatin into the cytosol
- 2At higher salt concentration the heterochromatin gets converted into euchromatin and comes out of the nucleus
- 3The nucleus does not burst but the heterochromatin leaches out first
- 4The nucleus does not burst but the euchromatin leaches out first✓
Correct answer
The nucleus does not burst but the euchromatin leaches out first
