REVISION OUTLINE
­ In order to undertake this task you will need to know:
• The Watson – Crick model of DNA (DNA structure and function)
• The theory of evolution and natural selection
• Thorough knowledge of the periodic table
•the Atomic theory
• Elements, compounds, chemical reactions and indicators
• Experiment procedure/skills
• Processing/analysing information from a variety of sources • Graphing BIOLOGY CONTENT:










Importance of fossils
Uses of biotechnology .
Concepts that support the theory of natural selection (simple, just evolution of galapagos finches and so on)
Natural Selection .
DNA structure .
DNA replication
Mutation .
Charles Darwin .
Evidence for Evolution and Natural Selection: comparative anatomy, comparative embryology, fossil record, biogeography and biochemistry

CHEMISTRY CONTENT:


Difference between elements, compounds, atoms and molecules







Electron configuration­ 2n 2
Structure of atoms­ nucleus(protons and neutrons inside) 1st shell and 2nd shell (electrons)
Common chemical compounds and their properties/chemical formula
Periodic table = how to read/interpret it
Different chemical reactions and the properties of chemical reactions (E.G. combustion, acid and metal reactions, acid and carbonate reactions)
Signs of chemical reactions
Use of indicators




ELECTROMAGNETIC SPECTRUM (NEW)




The Wave Model (features of waves, different types of radiation that makes up the twatts electromagnetic spectrum and their use).
Effects of electromagnetic radiation, including applications in communications technology

ELECTRICITY (NEW)





Series and Parallel circuits
Properties and Measurements (Current, Voltage, Resistance)
Diagrams ­ Symbols & Placement
Ohm’s Law (Also Wattage triangle)

SKILLS:





Interpreting information from secondary sources. This could involve simple comprehension or using information from a source to come up with a solution.
Reading/interpreting graph(s)
Drawing graph(s)
Writing up an experiment. (Revise what makes a good method, think about what you need to include in a method....variables....etc)

Genetics















DNA
DNA = Deoxyribonucleic acid structure is known as a double helix
Contains 4 bases:
Adenine, Thymine, Cytosine & Guanine
Adenine always pairs with Thymine.
Cytosine always pairs with Guanine.
Double Helix is supported by a sugar/phosphate backbone
Segments of DNA are known as genes (genes determine the organism’s characteristics and features in correspondence to it’s parent organisms)
Structure was first described by James Watson & Francis Crick in 1953
Other contributors include Rosalind Franklin & Maurice Wilkins
Double Helix
Similar To Twisted Ladder/Twisted
Staircase
Bases = First Letter Only (A,T,C,G)
A only pairs with T (A ­> T or T­>A)
C only pairs with G (C ­>G or G­>C)
Pentagon = Ribose (sugar)



= Phosphate (PO
)

What Is A Gene?
● Instruction manual for the body (a
Heredity unit)
● Controls particular characteristics
● Genes are the directions for all the proteins in our…
