What is the linear structure in the nucleus that contains DNA called?

• A. Genome
• B. Chromosome
• C. Gene
• D. Nucleosome

Answer: (B)

In the nucleus, DNA is organized into chromosomes, which are long, linear molecules that carry genetic information. Each chromosome contains many genes and regulatory elements, packaged with proteins into chromatin so the DNA fits inside the nucleus and can be accurately replicated and separated during cell division. A genome is the complete set of all chromosomes in a cell, a gene is a specific DNA sequence that codes for a product, and a nucleosome is the basic unit of DNA packaging—DNA wrapped around histone proteins. So the linear structure that contains DNA is a chromosome.
