Question

Which statement about the tertiary structure of eukaryotic DNA is FALSE?

Histones contain a high proportion of positively-charged amino acids.

Each molecule of DNA is far longer than the dimensions of the nucleus, and so it must be packed tightly to fit in.

The electrostatic interactions between DNA and histones have a lower bond energy than hydrogen bonds.

The beads on a string form of chromatin contains both nucleosomes and linker DNA.

Histones contain a high proportion of positively-charged amino acids.

Explanation / Answer

The electrostatic interactions between DNA and histones do not have lower bond energy than hydrogen bonds. They have higher energy, and thus are stronger and difficlut to break, making it tougher to unravel the tertiary structure of DNA. Thus, the statement "the electrostatic interactions between DNA and histones have a lower bond energy than hydrogen bonds" is FALSE.
