Answer:
D. is transcriptionally inactive.
Explanation:
Euchromatin is the part of chromosomes which are loose in form and are involved in the transcription process because these are available for the transcription into specific protein products. On the other hand, heterochromatin is the region of chromosomes that appears dark in staining process. This region is transcriptionally inactive because of the DNA template in the DNA-protein complexes and which means that genes present in the region are not active and not involved in the process of transcription.
Hope it helps!

Answer:
(look at the explanation below)
Explanation:
A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages.
