Explore deoxyribonucleic acid structure and replication with key enzymes, then cover transcription, translation, ribonucleic acid modifications, and the cell cycle, including mitosis, meiosis, and regulation by p53 and p21.
Explore DNA structure, including deoxyribose, phosphate groups, nitrogenous bases, and their hydrogen-bond base pairing, along with chromatin packaging around histones and epigenetic methylation and acetylation.
Explain how DNA replication uses the template strand to synthesize a new daughter strand, highlighting origin of replication, helicase, primase, DNA polymerase, leading and lagging strands, and telomere maintenance.
Learn how transcription uses DNA to form mRNA with initiation, elongation, and termination in eukaryotic nucleus and prokaryotic cytoplasm. Describe promoters and post-transcriptional modifications like capping and splicing.
Explore how cytoplasmic translation uses mRNA templates and ribosomes to synthesize proteins. Learn about tRNA charging by aminoacyl tRNA synthetase, initiation–elongation–termination, and ribosome subunits in prokaryotes and eukaryotes.
Explore the cell cycle and mitosis, detailing interphase with G1, S, G2, and G0, and the stages prophase through cytokinesis, including DNA replication and mitotic spindle mechanics.
Meiosis converts diploid cells to haploid gametes through two division cycles, with pairing of homologous chromosomes, crossing over at a chiasma, and formation of recombinant chromosomes that increase genetic variation.
Explore how the cell cycle is regulated by G1/S, G2/M, and M checkpoints that ensure DNA integrity, and how cyclin-CDK, E2F, RB, p53, and p21 govern progression and apoptosis.
Master the core principles of molecular and cell biology with this comprehensive, easy-to-follow course designed for students in medicine, biology, and related health sciences. Whether you're preparing for exams or building a strong conceptual foundation, this course breaks down complex topics into clear, high-yield lessons you can actually understand and apply.
You’ll start with the fundamentals of DNA structure, learning how genetic material is organized and maintained. From there, the course walks you step-by-step through DNA replication, transcription, and translation, helping you connect the entire flow of genetic information from gene to protein. Each concept is explained with a focus on mechanisms, key enzymes, and common exam-tested details.
The course then moves into cell division, covering both mitosis and meiosis in a structured and visual way, so you can clearly understand chromosome behavior, phases, and clinical correlations such as genetic disorders. Finally, you’ll explore the regulation of the cell cycle, including checkpoints, cyclins, and signaling pathways, with emphasis on how dysregulation contributes to diseases like cancer.
Designed with a student-first approach, this course emphasizes:
Clear, simplified explanations of complex mechanisms
High-yield concepts for exams like USMLE and other medical tests
Logical flow from basic science to clinical relevance
Efficient learning to save time without missing key details
By the end of this course, you’ll have a strong understanding of how cells function at the molecular level and the confidence to tackle advanced topics in medicine, genetics, and biomedical sciences.
