What you'll learn

  • The structure and function of DNA and RNA as the primary genetic materials in all living organisms.
  • The chemical composition of nucleotides and how they form the double helix structure of DNA.
  • The historical experiments that led to the discovery of DNA as the hereditary material (Griffith, Avery, Hershey-Chase).
  • The process of DNA replication, including the roles of enzymes like DNA polymerase, helicase, and ligase.
  • The stages of mitosis, including prophase, metaphase, anaphase, telophase, and cytokinesis.
  • The purpose and mechanisms of meiosis, including reduction of chromosome number and production of gametes.
  • How crossing over and independent assortment during meiosis increase genetic variation.
  • The cell cycle, including interphase (G1, S, G2) and regulatory checkpoints that ensure accurate division.
  • The similarities and differences between mitosis and meiosis in terms of outcome, chromosome number, and genetic variation.
  • The significance of cell division in growth, repair, reproduction, and maintaining genetic stability in organisms.

Course content

3 sections • 8 lectures • 1h 39m total length

  • Lecture 1 - DNA | The Molecule of Life5:11

    Explore the dna molecule, its double helix structure, base pairing, and how chromosomes, chromatids, and centromeres organize genetic information for cell division and heredity.

  • Lecture 2 - Discovery of The Genetic Material14:08

    Trace the discovery of genetic material from nuclein to DNA, and examine key evidence: griffith transformation, Avery's DNA, Chargaff's rule, Hershey-Chase, and the DNA double helix by Watson and Crick.

  • Lecture 3 - Structure of The Genetic Material8:42

    Identify Chargaff's rule and A-T and G-C base pairing that underpin DNA double helix. Examine Franklin and Wilkins X-ray insights, anti-parallel strands, and purine–pyrimidine pairing, plus DNA and RNA differences.

  • Lecture 4 - DNA Replication Process21:25

    Define the DNA replication process and describe its semi-conservative mechanism, leading and lagging strand synthesis, and the roles of helicase, primase, DNA polymerase, and ligase.

  • Lecture 5 - DNA Transcription Process16:56

    RNA polymerase transcribes DNA into mRNA using the template strand and promoter, in eukaryotic nuclei (prokaryotes in the cytoplasm), with initiation, elongation, termination, and capping, polyadenylation, splicing.

  • Lecture 6 - DNA Translation Process11:22

    Learn how mRNA is translated by cytoplasmic ribosomes into a polypeptide, using tRNA and codons from AUG to stop codons UAA, UAG, and UGA.
