Euchromatin is more tightly packed because it has a higher gene density. t/f

The answer is false.

Euchromatin is a lightly packed form of chromatin not tightly. Euchromatin is usually described as active chromatin, because DNA around the histones (which together form nucleosome) is loosely wrapped enabling transcription. So, euchromatin is rich in genes that are actively transcribed (RNA polymerase, transcription factors and other proteins can bind to DNA).

Under the microscope, euchromatin appears light in color, while heterochromatin (condensed DNA) is dark.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
