Define the terms genome and proteome.
Explain why modern phylogenetic classification of fungal pathogens using genome sequencing is more accurate than historical classification methods that relied on observing asexual spore structures (such as conidia) under an optical microscope.
In a study of fungal cell biology, a student measures the diameter of a spherical yeast cell in a printed electron micrograph.

Distinguish between the terms genome and proteome of a single-celled organism.
Explain why modern classification systems based on genome sequencing are far more reliable for determining evolutionary relationships between prokaryotes than traditional methods based on metabolic phenotypes (such as substrate utilization or optimal growth temperatures).
In an evolutionary study of archaea, a researcher measures the diameter of a spherical Methanococcus cell from a transmission electron micrograph.

Define the terms genome and proteome.
Explain why modern classification systems based on genome sequencing are more accurate than early classification methods that relied on observing physical characteristics of bacteria (such as the arrangement of flagella) under an optical microscope.
In a study of bacterial morphology, a student measures the length of an Escherichia coli cell in a printed electron micrograph.

Practise AQA A Level Biology Using genome projects (A-level only) with exam-style questions for A Level Biology. 3 questions covering Using genome projects (A-level only), matched to the AQA A Level Biology (7402) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
