Background: A geneticist discovers two genes that are involved in the cell cycle of C. elegans, a commonly used model organism. She studied the effects of these mutations in separate worm lines: aab+b+ and a+a+bb. to gain a better understanding of the cell cycle, she needs to create a double […]

Q1. What are two instances where microorganisms may someday be utilized to synthesize biopolymers most usually associated with products of the petrochemical industry today? Why are these studies important in the long term? Q2. Which lower vascular plant group once had tree-sized individuals (ca. 250- 300 mya) in swampy areas; […]

Today, scientific advances are being made at an astounding rate, and nowhere is this more evident than in our understanding of the biology of heredity. Using DNA as a starting point, do you believe there are limits to the knowledge people should acquire? Defend your answer.Because genetics is important to […]
