BIOLOGY students Tarlea Cantrill and Kathleen Anderson took a closer look at their DNA at a museum workshop.

The A-Level students from Witney's Henry Box School were at the A Question of Taste workshop at the Oxford University Museum of Natural History, in Parks Road, yesterday.

At the session, the teenagers investigated how some people can taste a bitter chemical, PTC, and some people cannot.

They analysed a bitter taste receptor gene from their DNA.

Miss Cantrill, 17, from Witney, said: “It was really interesting, the fact that I can use chemicals to be able to extract my DNA.

“It was also good finding out about myself and how my body works.

“I can’t taste anything bitter.”
