Which one of the following is NOT a component of eukaryotic chromosome?

Step-by-step solution

Eukaryotic chromosomes are highly condensed structures primarily composed of DNA and proteins. The proteins include basic histone proteins (which help in packaging DNA into nucleosomes) and non-histone proteins (which play structural, enzymatic, and regulatory roles). While RNA is synthesized from DNA during transcription and can be transiently associated with chromatin during the interphase of the cell cycle, it is not considered a structural component of the condensed eukaryotic chromosome. Answer: RNA
