    Episode 1

    In this lesson, we have a look at the structure of DNA and RNA and the differences and similarities between the two nucleic acids.

  • DNA replication and DNA profiling

    Episode 2

    In this lesson, we have a look at the process of DNA replication and how it takes place in living organisms. We also look at DNA profiling and the uses of this procedure in our everyday lives.

  • Protein synthesis

    Episode 3

    In this lesson, we take a look at the process of protein synthesis and the functions of the different RNA molecules during the process of protein synthesis.

  • Chemistry of life

    Episode 4

    During this lesson, we take a look at the process of meiosis and the importance of the process in halving the chromosome number in cells during the formation of gametes.

  • Mitosis and the similarities

    Episode 5

    Episode 6

    In this lesson, we take a closer look at the different reproductive strategies that are used by vertebrates and the advantages and disadvantages of each of these strategies.

  • Human reproduction; The male reproductive system

    Episode 7

    In this lesson, we have a look at the structure of the male reproductive system, and the functions of the different parts of the reproductive system. We also have a look at the structure of sperm.

  • Human reproduction; The female reproductive system

    Episode 8

    In this lesson, we deal with the structure of the female reproductive system and the functions of the different parts. We look at the process of gametogenesis in both males and females.
