Which of the following statements describes chromatin? a) heterochromatin is composed of dna, whereas euchromatin is made of dna and rna. b) both heterochromatin and euchromatin are found in the cytoplasm. c) heterochromatin is highly condensed, whereas euchromatin is less compact. d) euchromatin is not transcribed, whereas heterochromatin is transcribed. e) only euchromatin is visible under the light microscope.

The correct answer y C).

Explanation:

Chromatin is the association between DNA and proteins called histones.

Heterochromatin is highly condensed because in that state  the union between DNA and proteins is very strong and they are very close.

Euchromatin is less compact because in that state the union between DNA and proteins is weak and they are less stuck together.

Heterochromatin is not transcribed, whereas euchromatin is transcribed because when the union between DNA and histones is very strong, DNA is in a very compact state and the transcription machinery (RNA polymerase, transcription factors, etc.) cannot access the DNA to be able to transcribe it.
