Chapter 7 / 5 short lessons
Genomes and gene regulation
Explain how the same genome produces different cells, and locate control using experimental evidence.
H2 Biology / 9477 / 2027 syllabus
What do you think?
Two cells have the same gene but different amounts of its protein. Must one have a mutation?
