Which among the following statement is not correct about heterochromatin ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2)-It is transcriptionally active.
The statement that is not correct about heterochromatin is: It is transcriptionally active.
Heterochromatin is a tightly packed form of chromatin that appears darkly stained under a microscope. It is generally transcriptionally inactive or transcriptionally repressed, meaning that the genes within heterochromatin are not actively transcribed into RNA. In contrast, euchromatin, which is a less condensed and more open form of chromatin, is associated with active transcription of genes. Therefore, the correct statement is that heterochromatin is transcriptionally inactive.
