Hello everyone here we have a question that says the DNA molecule is wrapped around an optimum eric core of blank proteins to make a nuclear zone A chroma tin chroma tin is a complex of D. N. A. And protein found in nuclear sales. So A. Is wrong be histone. The DNA molecule is wrapped around an optimistic core of histone proteins to make a nuclear zone. So B. Is correct. But let's look at all of their options. See keratin, keratin is a type of structural protein found in the hair, skin and nails. So C. Is incorrect. And lastly we have right zone. A. Rhizome is an inter cellular structure made of both R. N. A. And protein and it is a site of protein synthesis of the cell. So D. Is incorrect. So our answer here is be his stone. Thank you for watching. Bye.
