Gene Technology | A Level Biology Revision | AQA

Gene technologies enable the study and modification of gene function, enhancing our understanding of how organisms operate and facilitating the development of new industrial and medical applications.

For the A Level Biology exam, you will be required to know this in sufficient detail to explain:
a) how genes are studied and altered
b) the implications for understanding organism function
c) the design of new industrial and medical processes

This knowledge is crucial for illustrating the role of gene technologies in advancing scientific research and practical applications in various fields.

EXAM TIP: AQA students should focus on the practical applications and implications of gene technology.

This content is tailored for A-Level Biology AQA & OCR students.
