(b)या प्रथिनांमध्ये आरजेनीन व लायसीन या मूलभूत अमिनो आम्लाचा जास्त प्रमाणात सहभाग असतो. / These proteins are rich in basic Amino Acids Argenine and Lysine.
(c)या प्रथिनांमध्ये टोप्टोफॅन या मूलभूत आम्लाचा अभाव असतो. / These protein lack Trptophan.
In eukaryotic cells, DNA is wound around histone proteins rich in basic amino acids like arginine and lysine, and histones notably lack tryptophan.
