Students often find the topic of DNA quite a tricky one. Through exposure in the media and popular science, students are aware of the molecule and know that genes are used to carry information. However, a great deal more detail is required by the specifications and there is always the risk that students have deep-held misconceptions. For example, in the relative scale of the molecule, nucleus and whole cell.
In this list, several of the resources look to assist students in gaining an in-depth understanding of the structure of the DNA molecule. Using models and animations help to provide a range of ways in which students can tackle this abstract concept.
Finally, an animation that shows how DNA is used to drive protein synthesis is included. This is a very tricky process and time should be set aside to make sure that it is understood.
Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment. Further information is provided in our Health and Safety guidance.
