Cell Bio - Stages of Genetic Engineering

Question 1

Define Genetic Engineering

Answer 1

It is the transfer of DNA from one organism to another using biotechnology.

Question 2

What is the purpose of Genetic engineering?

Answer 2

It is used to genetically modify organisms to give them a mix of genes (genotype) that result in them having desirable physical characteristics. (phenotypes).

Question 3
