Passage / Scenario
Which of the following contains a human's hereditary information?
Correct answer
C
Rationale
The correct answer is C: Chromatin. Chromatin is a complex of DNA and proteins found in the nucleus of a cell. It serves to package the DNA into a condensed structure, which aids in its regulation and gene expression. Plasmids are small DNA molecules typically found in bacteria, histones are proteins that assist in organizing DNA into nucleosomes, and ATP is a molecule involved in cellular energy transfer. None of these choices contain the specific hereditary information unique to humans, which is encapsulated within chromatin.
