The beadlike complex of DNA wrapped around histone protein is called a:
ANucleoid
BNucleolus
CNucleotide
DNucleosome
Answer & Solution
Correct answer: D. Nucleosome
1. DNA must be compacted many times over to fit inside a nucleus.
2. The first level of packing winds the strand around protein cores.
3. Each beadlike histone-DNA complex is called a nucleosome, and DNA connecting the nucleosomes is called linker DNA.
4. A nucleoid is the DNA-holding region of a prokaryote, and a nucleotide is a single DNA building block.
