What is recombinant DNA technology?
Recombinant DNA technology involves combining DNA from different organisms to create new genetic combinations.
Fill in the blank: __________ is a technique used to separate DNA fragments by size.
Gel electrophoresis
What are stem cells?
Stem cells are unspecialized cells that have the potential to develop into different cell types.

What is tissue culture?
Tissue culture is a technique used to grow cells or tissues in a controlled environment outside of their natural habitat.
Fill in the blank: __________ are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.
Antibodies
What is the role of PCR (Polymerase Chain Reaction) in biotechnology?
PCR is used to amplify small segments of DNA, making millions of copies for analysis.

True or False: Biotechnological advancements have no impact on healthcare.
False
What is the primary goal of gene therapy?
The primary goal of gene therapy is to treat or prevent diseases by modifying the genes responsible for the disease.
Fill in the blank: __________ is the process of creating a genetically identical copy of an organism.
Cloning
What are GM crops?
GM crops are plants that have been genetically modified to exhibit traits such as resistance to pests or improved nutritional content.
Which ethical concern is commonly associated with biotechnology?
The potential risks and consequences of genetic modification on health and the environment.
