- biology topic two
- cystic fibrosis
- is a result from one of a number of possible gene mutations
- understand how the expression of a gene mutation in people with cystic fibrosis impairs the functioning of the gaseous exchange, digestive and reproductive systems
- properties of transport materials across cell membranes and gas exchange surfaces
- know the properties of gas exchange surfaces in living organisms
- understand how the rate of diffusion is dependent on these properties and can be calculated using Fick's law of diffusion
- understand how the structure of the mammalian lung is designed for rapid gas exchange
- know the structure and properties of cell membranes
- understand how models are used to interpret data for scientific explanations
- movement in cells: osmosis, passive transport, active transport, endocytosis and exocytosis
- understand the involvement of carrier and channel proteins in membrane transport
- DNA structure and replication
- know the structure of mononucleotides and structures of DNA and RNA
- double helix: complementary base pairing and hydrogen bonding between two complementary strands are involved in the formation.
- protein synthesis process: RNA polymerase, translation, messanger RNA, transfer RNA, robosomes and the role of start and stop codons
- understand the roles of: DNA template strand in transcription, codons on messenger RNA and anti-codons on transfer RNA
- understand the nature of the genetic code
- a gene is a sequence of bases on a DNA molecule that codes for a sequence of amino acids in a polypeptide chain
- understand the process of DNA replication, including the role of DNA polymerase
- unsderstand how meselson and stahl's classic experiment provided new data that supported the accepted theory of replication of DNA and refuted competing theories
- understsnd how errors in DNA replication can give rise to mutations
- proteins
- know the basic structure of an amino acid
- understand the significance of a proteins primary structure in determining its 3D structure and properties
- understand the formation of polypeptides and proteins
- protein synthesis
- know the molecular structure of a globular protein and a fibrous protein and understand how their structures relate to their functions
- understand the mechanism of action and the specificity of enzymes in terms of tehir 3D structure
- enzymes are biological catalysts that reduce activation energy
- there are inracelluar enzymes catalysing inside cells and extracellular enzymes produced by cells catalysing reactuions outside of cells
- enzymes and monohybrid inheritance through the context of the genetic disease cystic fibrosis
- understand the meaning of the terms: gene, allele, genotyoe, phenotyoe, reccesive, dominant, imcomplete dominance, homozygote and heterozygote
- understand patterns of inheritance inlcuding the interpretation of genetic pedigree diagrams, in the context of monohybrid inheritance
- social amd ethical issues surrounding genetic screening for genetic conditions
- understand the uses of gentic screening, including the identification of carriers, pre-implantation genetic diagnosis and prenatal testing including amniocentesis and chorionic villus sampling
- understand the implications of prenatal genetic screening
- be able to identify and discuss the social and ethical issues related to genetic screening from a range of ethical veiwpoints
- maths
- areas of shapes
- volumes
- fractions and percentages
- ratios
- plotting data
- interpreting graphs
- cystic fibrosis
