Welcome to Biological Science Advanced Studies. This site is designed for biology students of A-level, AS and A2, covering the related topics in Biology and Human Biology.
The video left out the cause of sickle cell anaemia which is a defective gene causing the order of aminoacids in some of the polypeptide chains to change.The new HaemoglobinS tertiary structure is changed resulting in less solubilty and it also causes it to crystalise in low oxygen concentrations. It also left out codominance of the gene and natural selection favouring heterozygous alleles due to resistance to malaria.
