The process in which a piece of DNA is modified for use in research, medicine, agriculture, or industry

What is genetic engineering? 

300

A base, a sugar, and a phosphate group that make a building block of DNA

What is a nucleotide? 

300

a base is left out

deletion

300

The process of selecting and breeding organisms that have certain desired traits

What is artificial selection? 

400

Changes in the number, type, or order of bases on a piece of DNA

What are mutations? 

400

an extra base is added

insertion

400

An organism, cell, or piece of genetic material that is genetically identical to the one from which it was derived

What is a clone? 

500

a type of molecule that determines the traits that an individual inherits

What is DNA?

500

happens when one base replaces another

substitution

What are the benefits and risks of using biotechnology?

The benefits of biotechnology are as follows:

  • Environmental safety and protection.
  • It improves crop productivity. 
  • It causes a remarkable improvement in human health. 

Some risks that are associated with biotechnology include the reduction of genetic diversity because of genetically modified technology. It may also be regarded as the most potent threat to biodiversity. The inheritance of selective traits causes natural imbalances in the environment.
