Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson. Each SLM is composed of different parts. Each part shall guide you step-by- step as you discover and understand the lesson prepared for you. Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these. In addition to the material in the main text, Notes to the Teacher are also provided to our facilitators and parents for strategies and reminders on how they can best help you on your home-based learning. Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task. If you have any questions in using this SLM or any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator. Thank you.

Can you cite the techniques in genetic engineering scientists utilize in creating outcomes? 5 CO_Q2_ELS SHS Module 4 What Is It Since ancient times the practice of genetic engineering had begun. Artificial selection is done to indirectly manipulate genes focusing on the physical traits among organisms. Breeders choose which organism to mate and produce offspring with desirable traits. They maintain this procedure without control of what genes can be passed. Selective breeding is a process when animals with desired characteristics are mated to produce offspring with those desired traits such as Angus cows are bred to increase more meat. Hybridizations are when two individuals with unlike characteristics are crossed to produce the best in both organisms like the disease resistant potato called the Burbank potato. Inbreeding is a technique of breeding organisms that are genetically similar to maintain desired traits found in the pure dog breeds. As defined, genetic engineering is the process of changing the DNA in living organisms to create something new. It involves artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules to modify an organism or population of organisms. Recombinant DNA Technology Recombinant DNA is made by mixing DNA from two different sources. Restriction enzymes were discovered in 1968 by Swiss microbiologist Werner Arbe. This was used to splice, connect (or ligate), and remove or add nucleotides to sequences of the DNA. This process is used in recombinant DNA technology to remove and insert genetic sequences from and into other sequences of other organisms. Inserting the desired gene into the genome of the host involves the selection of the desired gene for administration into the host followed by a selection of the perfect vector (either plasmid or bacteriophage) with which the gene has to be integrated and a recombinant DNA is formed. The recombinant DNA has to be introduced into the host, maintained and carried forward to the offspring. Biotechnology and pharmaceutical companies practice these techniques in working with medical and research purpose. 6 CO_Q2_ELS SHS Module 4 What’s More Activity 3: Match me!
