Answer:
The correct answer is 1.
Explanation:
Chromosome is a thread-like structure made up of supercoiled DNA around the histone proteins present in the nucleus.
Each chromosome is made up of only one DNA molecule. A chromosome is a compact form of DNA and this compaction is necessary to fit a 2.2 meter long DNA in the microscopic nucleus.
Each chromosome contains thousands of genes made up of nucleotides and is responsible for their regulation. Each DNA compact into a chromosome in the prophase stage of mitosis.
Thus, the correct answer is 1 molecule of eukaryotic DNA make up a chromosome in humans.
