Careers from biology
In 'Big Picture: Careers From Biology', we've profiled several people with different careers to show where post-16 qualifications in biology can lead. In this gallery, browse some images related to these occupations - can you work out which of our case studies each picture relates to?
All of these images are free to use in your classroom. For more scientific and medical images, see Wellcome Images.
HPV in cervical epithelium

A lesion in human cervical epithelium infected with human papilloma virus (HPV16). Early viral proteins (green) bind to and reorganise the keratin filaments (red) towards the edge of the cell. Cell nuclei are stained with DAPI (blue).
This image was featured on the back of ‘Big Picture: Careers From Biology’, and the case study it relates to is Gift Nambela, whose work involves running assays to detect human papilloma virus.

Scientist studying DNA sequence data
IMAGE 2 of 12
|
A scientist studying a sequence of DNA looking for alignment of the sequence relating to the Lipl32 gene, which is present among pathogenic leptospires (a genus of Gram-negative bacteria).
The alignment was performed to find a consensus sequence that could be used to generate a set of DNA primers and a probe to be used in a real-time PCR assay. This assay will allow scientists to target the specific DNA sequence to detect the presence of this DNA sequence, and thus pathogenic leptospires, in urine.

Environmental management

This canal was built around an urban settlement in the Middle East so the rodent reservoir hosts of Leishmania would not be able to swim over and reinvade an area where the rodent population had previously been controlled.

This biohazard symbol is often used to warn of a potential biological hazard. This could be an organism or a substance derived from an organism and might include medical waste or samples of a microorganism, virus or toxin.

Humulus lupulus (hops)
|
IMAGE 12 of 12
|
A herbaceous climbing plant with coarse-toothed leaves and ‘hop’ flower heads. The cone-like flowers are traditionally used in beer brewing for their distinctive, bitter flavour. The young shoots have also been eaten as a vegetable, rather like asparagus. Extracts containing lupulin have also been used as a galactagogue (to increase the flow of milk in nursing mothers).
