GCSE Biology - Genetic Engineering #82

The video explains genetic modification, where genes from one organism are transferred to another to develop desired traits. It covers applications like genetically engineered sheep and bacteria, and modified crops. Gene therapy is discussed as a potential treatment for genetic disorders, though it faces challenges. The pros and cons of genetically modified crops are explored, highlighting benefits like increased food production and concerns about health and ecological impacts. The process of gene transfer using vectors is also explained.

What is the primary goal of transferring a gene from one organism to another?

• To increase the organism's size

• To create a new species

• To eliminate the original organism

• To develop a desirable trait in the recipient organism

Which of the following is a challenge faced by gene therapy?

• Finding a suitable gene to transfer

• Transferring the gene into every cell of the body

• Creating a new organism

• Producing insulin in bacteria

What is one potential solution to the challenge of gene therapy?

• Transferring the gene at an early development stage

• Using a different species' gene

• Transferring the gene at the adult stage

• Eliminating faulty genes

What is a benefit of genetically modified crops?

• They require no water

• They are immune to all diseases

• They can survive in the wild

• They can produce more food for less money

How is a gene typically transferred from one organism to another?

• By direct injection into the organism

• Using a vector like a virus or bacterial plasmid

• Through natural selection

• By cross-breeding
