Question

Nucleosomes are best described as:

(a) Eukaryotic DNA associated with histone proteins.
(b) Prokaryotic DNA associated with nonhistone proteins.
(c) Eukaryotic DNA associated with nonhistone proteins.
(d) Prokaryotic DNA associated with histone proteins.

Answer 1

Nucleosomes are eukaryotic DNA associated with histone proteins and are like 'beads on a string'. They control access to the DNA by other proteins.

Step-by-step explanation:

Nucleosomes are best described as eukaryotic DNA associated with histone proteins. Histones are proteins that wrap around the DNA, forming structures called nucleosomes. Nucleosomes are like 'beads on a string', and they control access to the DNA by other proteins. This packaging of DNA allows it to fit inside the nucleus of eukaryotic cells.
