Which of the following differences between euchromatin and heterochromatin is/are correct?

While heterochromatin is transcriptionally inactive sequences; euchromatin is transcriptionally active sequences.

Euchromatin is present in both prokaryotes and eukaryotes while heterochromatin is present only in eukaryotes.

Choose the correct answer using the codes given below:

Question

Euchromatin is a more lightly packed DNA that is characterized by less enormous staining and DNA sequences that are transcriptionally active or might become transcriptionally-active at some point during growth.
Heterochromatin is a firmly packed or condensed DNA that is characterized by enormous stains when stained with nuclear stains and transcriptionally inactive sequences.
Euchromatin consists of less amount of DNA lightly compressed with the histone proteins. Heterochromatin consists of more amount of DNA tightly compressed with the histone proteins.
Euchromatin is present in both prokaryotes and eukaryotes. Heterochromatin is present only in eukaryotes.
