Key topics that
came up Section B
only - Biology Paper
2: Biological
diversity
, 2022:
Biological Molecules - Globular proteins, bonds in proteins, level of protein structure.
Colorimeter
Nucleotides and Nucleic Acids - role of RNA polymerase, mutations
Cloning and Biotechnology - culturing bacteria - septic techniques, estimating the total
number of bacteria, the growth curve, using microorganisms in food production (pros +
cons), Batch and Continuous Fermentation
Ecosystems - Masai Mara case study, how increasing human population brings negative
impact on biodiversity, reasons for maintaining biodiversity
Population and Sustainability - sustainable fishing
Biodiversity/Classification and Evolution - types of variation (discontinuous or continuous),
Sampling techniques, Simpson’s Index of Diversity
Cellular Control - Body plans
2021
Nucleotides and Nucleic Acids - structure of DNA, nucleotide components, bonds and
reactions. Why DNA is “non-coding”
Manipulating genomes - Steps in producing a DNA profile, and uses. DNA sequencing
