ACTIVITY 1.1: Let's Warm Upl INSTRUCTIONS/ GUIDE QUESTIONS: Identify the potential applications of recombinant DNA in crop improvement by matching the applications in column A with their meanings in Column B. Write the letter of the correct answer in a separate sheet of paper. COLUMN A COLUMN B APPLICATIONS IN CROP MEANING/DEFINITION IMPROVEMENT 1. Development of Transgenic A. The desirable genes can be transferred even from Plants lower organisms to higher organisms. 2. Development of Root B. Resistance to diseases, Insects and pests, Nodules in Coroal Crops herbicides, drought, metal toxicity tolerance; Induction of male sterility for plant breeding purpose; and improvement of quality can be achieved. 3. Development of C4 Plants C. Improvement in yield can be achieved by improving the photosynthetic efficiency of crop plants. 4. Genetic Modified Foods D. Production of interferon by recombinant DNA (GMF) technology at much cheaper rate. 5. Distant Hybridization E. Recombinant DNA has increased the overall production of crops, as well as decreased the amounts of herbicides and insecticides used by farmers. F. Through genetic engineering techniques, the bacterial genes responsible for nitrogen fication may now be transferred to cereal crops making it capable of fixing atmospheric nitrogen as well.

Ans: The potential applications of recombinant DNA in crop improvement is 4. Genetic Modified Foods(GMF) is the correct answer ( in column A)
The explanation is given below
Step-by-step explanation
The Recombinant DNA has increased the overall production of crops as well as decreased the amounts of herbicides and insecticides used by farmers. This means the farmers produces larger amounts of foods while spending the less time caring for the crops and paying less for herbicides and insecticides which comes under Genetic Modified organisms. So the answer is Genetic Modified Foods (GMF).
Ans:
4. Genetic modified foods (GMF) In column A is matches to E. Recombinant DNA has increased the overall production of crops as well as decreased the amounts of herbicides and insecticides used by farmers in column B
