• B. DNA -> Gene -> Chromosome -> Nucleus
• C. Nucleus -> DNA -> RNA -> Chromosomes
• D. none of the above

Answer 1

The correct option is B

DNA -> Gene -> Chromosome -> Nucleus

The nucleus is the organelle present in cells which contains genetic material. The nucleus controls all the processes in the cell. Specific portions of DNA having special properties are called as genes. The very long DNA gets packaged to fit inside the nucleus. The packaging hierarchy is DNA --> Genes --> Chromosomes --> Nucleus.
