Question 4 • CMS 2026-2027 Biology CREDIT RECOVERY

Scientists have been able to inject the firefly's lighting gene into a tobacco plant, allowing it to glow. Which type of organism is this tobacco plant?

Answer
A
recombinant organism
B
restriction organism
C
vector organism
D
transgenic organism

Explanation

A transgenic organism has DNA from another species inserted into its genome. The tobacco plant received the firefly’s lighting gene, so it is a transgenic organism. A vector is something used to carry genetic material, not the organism that receives it.
