The DNA code of life
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
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.
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
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
During this lesson, we revise the process of mitosis from Grade 10 and look at the similarities and differences between the processes of mitosis and meiosis.
Reproduction in vertebrates
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
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
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.
Human reproduction; menstrual cycle and fertilisation
In this lesson, we have looked at the menstrual cycle of humans in detail and also discuss the process of fertilization in humans
Pregnancy and birth control
In this lesson, we take a look at pregnancy and the different stages of pregnancy. We also discuss the hormones that play a role in the maintenance of pregnancy and the different fetal membranes. We discuss the process of birth in humans and we also look at the different types of birth control ...
