Benefits of genetic engineering. Insect and pest resistance can be developed and inserted into the plants. The plant produces toxins, which would discourage insects from eating the crop. Sterile insects could be created such as a mosquito. They would breed, which would lead to infertile offspring.
May 06, 2016 In this GCSE Biology revision video, Hazel explains how genetic engineering is carried out, and provides examples of how it is used by scientists.

As soon as Id created an account on My GCSE science and saw the organisation and layout, it motivated me to watch every video and learn what I needed to learn. My teachers predicted a grade 55, but I wanted to do better. So I revised on My GCSE science and I reckon 90 of what I learnt was through your site.
Biology Genetic Engineering (AQA Syllabus A) Selective breeding has been used to modify the characteristics of plants and animals to better suit our needs. Examples are disease resistant plants, or cattle that give high yields of milk. But there are problems with this, since future generations of selectively bred organisms will share increasingly similar genes.
The item you are looking at is an exam question and mark scheme for the B1 Genetic Engineering lesson. This resource is based around students getting more marks in long answer questions as this is the area were they loose most marks.
