This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. 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.
DNA or deoxyribonucleic acid is a genetic material made of nucleotides. In the previous lesson, we learned how proteins were created through transcription (DNA codes are copied into mRNA) and translation (mRNA into linked amino acids). However, in this module we want to learn how those processes can “go wrong” and create mutations. In this module, you will investigate a gene mutation in which there is a change in one nucleotide. You will determine how these changes affect the way the message is transcribed into mRNA and translated to protein.
This module will introduce you to the effects of gene mutations. So, stay tuned and have fun learning the following:
1. Explain how mutations may cause changes in the structure and function of a protein.
Going through this module can be a meaningful learning experience. All you need to do is make use of your time and resources efficiently. To do this, here are some tips for you:
1. Take the pretest (What I Know) before reading the rest of the module.
2. Take time in reading and understanding the lesson. Follow instructions carefully. Do all activities diligently. It is better to be slow but sure than to hurry and miss the concepts you are supposed to learn.
3. Use a separate sheet of paper for your answers in each activity or assessment. Don’t forget to write your name. Label it properly.
4. Try to recall and connect the ideas about the lessons that you had in the lower years. Use the concept discussed in the lesson to explain the results of activities or performance task.
5. Be honest. When doing the activities, record only what you have really observed. Take the assessments after each activity, but do not turn to the Answer Key page unless you are done with the entire module.
6. Don’t hesitate to ask. If you need to clarify something, approach or contact your teacher or any knowledgeable person available to help you. You may also look into other references for further information.
7. Take the post-test prepared at the end of the module, so you can assess how much you have learned from this module.
8. You can check your answers in the activities, self-assessments, and post-test after you finished the entire module to know how much you have gained from the lesson and the activities.
