Active genes are found in the
A) heterochromatin.
B) euchromatin.
C) Barr bodies.
D) promoters.
E) operons.
Active Genes
Sections of DNA that are being transcribed and translated into proteins, influencing the traits of an organism.
Heterochromatin
A tightly packed form of DNA, which is transcriptionally inactive, aiding in maintaining the DNA's structural integrity.
Euchromatin
A lightly packed form of chromatin (DNA, RNA, and protein complex) that is enriched in gene concentration and is active in transcription.

Final Answer :
B
Explanation :
Active genes are found in euchromatin, which is the less condensed and more accessible form of chromatin. Heterochromatin is highly condensed and can result in gene silencing. Barr bodies are inactive X chromosomes in female mammals. Promoters and operons are specific regions within genes that play a role in gene expression, but they do not determine whether a gene is active or inactive on their own.
