Question

The chromosome of yeast has molecular mass

• A. ${1\times 10}^9$ daltons
• B. ${0.5\times 10}^9$ daltons
• C. ${2.50\times 10}^9$ daltons
• D. ${1.2\times 10}^8$ daltons

Answer 1

The correct option is D ${1.2\times 10}^8$ daltons

Electron microscopic analysis indicates that yeast nuclear DNA can be isolated as linear molecules ranging in size from 1.2 X 10${}^8$ daltons to 8.4 X 10${}^8$ daltons.

Therefore, the correct answer is option D.
