CONSERVATION GENETICS

Join us as we explore the work of our Living with Tigers project team in Nepal, who are helping to reduce human-wildlife conflict using the latest gene technology.

In this workshop students will use scientific skills to prepare a faecal sample for DNA analysis and investigate the theory behind PCR and gel electrophoresis. Students will develop micro pipetting skills and interpret results to determine who is responsible for the recent spate of livestock losses.

Age group: Post 16

Duration: 1 hour 15 minutes

Capacity: 25 students

Meeting point: Learning Centre

Cost: £28

Please note: Chester Zoo discovery workshops can be adapted to your learners needs and abilities, please speak to one of the team to find out more.

AQA 3.4.7
Investigating diversity

Genetic diversity within, or between species, can be made by comparing:

the base sequence of DNA

Students should be able to:

  • interpret data relating to similarities and differences in the base sequences of DNA … to suggest relationships between different organisms within a species and between species
  • appreciate that gene technology has caused a change in the methods of investigating genetic diversity; inferring DNA differences from measurable or observable characteristics has been replaced by direct investigation of DNA sequences.
AQA 3.8.4.3
Genetic fingerprinting (A-level only)

An organism’s genome contains many variable number tandem repeats (VNTRs). The probability of two individuals having the same VNTRs is very low.

The technique of genetic fingerprinting in analysing DNA fragments that have been cloned by PCR, and its use in determining genetic relationships and in determining the genetic variability within a population.

The use of genetic fingerprinting in the fields of forensic science, medical diagnosis, animal and plant breeding.

Students should be able to:

  • explain the biological principles that underpin genetic fingerprinting techniques
  • interpret data showing the results of gel electrophoresis to separate DNA fragments
  • explain why scientists might use genetic fingerprinting in the fields of forensic science, medical diagnosis, animal and plant breeding.
