In tertiary structure of $DNA$, what is a histone octamer?
A complex consisting of eight positively charged histone proteins (two of each $H2A, H2B, H3 and H4$) that aid in the packaging of $DNA.$
A complex consisting of eight negatively charged histone proteins (two of each $\mathrm{H} 2 \mathrm{~A}, \mathrm{H} 2 \mathrm{~B}, \mathrm{H} 3$ and $\mathrm{H} 4$ ) that aid in the packaging of DNA.
