Under Construction!!!!! I'm updating the Year 2 Pages as the year progresses to reflect the changes in the specs. Bear with me :)

Unit 5

The final examined unit of the Biology A-level

5.1 Genetic Code

The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins (see 1.1) by living cells (see 1.2)

5.2 Sexual Reproduction (in Humans)

Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from the parent or parents

5.4 Inheritance

Not the practice of passing on property, titles and goods on after the death of an individual, but passing on an individuals genes.

5.5 Variation and Evolution

Evolution is the change in the inherited characteristics of biological populations over successive generations. It only works if there is variation with a population

5.6 Application of reproduction and genetics

Biotechnology is the use of living systems and organisms to develop or make useful products

5.7 Energy and Ecosystems

An ecosystem is a community of living organisms (plants, animals and microbes; the biotic components) in conjunction with the non-living (abiotic) components of their environment (things like air, water and mineral soil), interacting as a system
