My name is Younes and I give language lessons, for me teaching means learning twice so my learning method is based on simplicity and above all you have to move forward according to the student's rhythm to allow him to learn. improve and acquire new bases and be able to assimilate new information without ever becoming saturated. Sometimes it's better to go slowly but surely. In addition, I am a young researcher in applied biochemistry and a temporary teacher at the university for 4 years, so for those who have difficulties and gaps in biochemistry, I will be there to simplify you and above all to make you discover the world. wonder of biochemistry and thank you for stopping by.

With a Master's degree in biomedical sciences, I offer biology tutoring courses adapted to all ages and levels. Passionate about teaching, I cover various areas of biology, including general biology, cell biology and molecular biology. Whether you are in high school, university, or wish to deepen your knowledge, I adapt to the needs and pace of each student to ensure a solid understanding of the concepts.

In this module I tutor in biology on a middle school to high school to college level, depending on what is required by the student. The possibilities vary from simple lessons about basic concepts all the way to the topics needed to pass ''end exams'' like the SAT, GCSE, MCAT and International Baccalaureate. My knowledge from medical school help me explain the material on a deeper level if the student requires so.

I'm a pharmacist, graduated from Faculty of Pharmacy, Ain Shams University, and hold a Master's degree in Analytical Chemistry. My goal is for students to understand important scientific subjects such as biology and chemistry without fatigue and to enjoy studying them. I give homework and submit periodic reports on the student's progress in their studies.

Unlock the secrets of life at the molecular level with this dynamic online biochemistry course! Dive into the chemistry behind living systems—explore how proteins, DNA, enzymes, and metabolism shape every aspect of biology. Whether you’re new to the subject or seeking to deepen your expertise, each lesson is tailored to your background and interests. Perfect for students, professionals, or anyone curious about the molecules that drive life.

I adapt to the profile of each intern or student according to their objective and level. The goal is not to work endless hours, but to show how to be able to work alone or partially independently in a short time. It is always a pleasure for me to be recognized in the street 15 years after classes, and to be thanked for having provided a real service to the person concerned. This activity is a passion of mine that I have been pursuing since I was 16 years old. I hope to be able to share it with you to prepare effectively, by significantly reducing your legitimate apprehension of exams.

I'm a Phd in Cell and Molecular biology and i can teach Cell Biology, Genetics, Molecular biology, Hematology, Endocrinology for University Students. In my Cell Biology class, master how cells work and communicate. This class covers the cell structure, cell cycle, cell membranes, membrane transport, action potential, signalling pathways, cell motility and cytoskeleton, mitochondria, bioenergetics—ideal for biology, medicine, or health science majors needing clear explanations and academic support. I use videos and carefully selected images to make complex scientific concepts easier to understand and more engaging. My teaching style is clear and patient — I speak slowly and adjust my pace based on the student’s level to ensure full comprehension. I can teach in English and French depending on the student’s preference. With over 15 years of university teaching experience, I tailor my lessons to each student’s goals and background.

Protein Synthesis – Edexcel A-Level Biology (Brief Class Summary) 1. Overview Time: 10minutes Protein synthesis is the process by which cells build proteins based on genetic instructions. It occurs in two main stages: transcription and translation. 2. Key Stages Time: 40 minutes a) Transcription (Nucleus) - DNA unzips and RNA polymerase reads the template strand. - mRNA (messenger RNA) is synthesized using complementary base pairing. - mRNA leaves the nucleus via nuclear pores. b) Translation (Ribosome – Cytoplasm) - Ribosomes read the mRNA codons. - tRNA brings specific amino acids to the ribosome. - Anticodons on tRNA match with codons on mRNA. - Amino acids link via peptide bonds, forming a polypeptide. 3. Important Molecules - DNA– Stores genetic code. - mRNA – Temporary copy of gene. -tRNA– Transfers amino acids. -Ribosomes – Site of protein synthesis. -Amino Acids– Building blocks of proteins. 4. Conclusion Time: 10 Minutes - Understand codon-anticodon matching. - Be able to describe transcription and translation step-by-step. - Practice interpreting DNA → mRNA → amino acid sequences.

Who among you has visited a mountain or seen rocks of different colors and shapes? Why do you think the rocks are different? Let's find out together! 1. Igneous rocks: They are formed by volcanoes after magma (lava) cools. An example from the Saudi environment: the Harrat Rahat rocks south of Medina. Appearance: dark, hard, and perforated. 2. Sedimentary rocks: It is formed by the accumulation of layers of sand and clay over time. Local example: Rocks in the Great Nafud Desert. Its shape: clear layers, easy to crumble. 3. Metamorphic rocks: It is formed by the alteration of other rocks due to pressure and heat. Example: Metamorphic granite rocks in the Hejaz Mountains. Its shape: its colors are intertwined and strong.
