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.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
