Quick Answer

Eukaryotic chromosomes are primarily composed of histone proteins, which are crucial for packaging DNA into chromatin. This has been confirmed through various experiments including electron microscopy, ChIP, mass spectrometry, biochemical analysis, and genetic studies. Nonhistone proteins are also present but do not form the primary scaffold.
