Example of biology being used in engineering or technology

gene therapy, cloning and genetic engineering

Explanation:

Gene therapy is the replacement of faulty defectie genes with the normal ones aimed at correcting genetic disorders. In somatical gene therapy, genetically modified organisms, e.g., viruses are used to carry the normal gene and introduce it into the affected cells. This is used to treat lung cystic fibrosis.

Cloning is a type of reproduction where a group of cells arise from single individual cells without fertilisation. The nucleus from a fertilised ovum is removed and replaced with a diploid nucleus of a cell from the mammary glands of another sheep.

Genetic engineering deals with identification of desirable genes, altering, isolating and transferring the gene from one living organism to another.
