What is a plasmid?

Back

A plasmid is a small, circular piece of DNA found in bacteria that can carry foreign genes.

Front

What is genetic engineering?

Back

Genetic engineering is the manipulation of an organism's DNA to produce desired traits, such as producing medicines, food animals, and improved crops.

Front

What is DNA fingerprinting?

Back

DNA fingerprinting is a technique used to identify individuals based on their unique DNA patterns, as no two people (except identical twins) have exactly the same DNA.

Front

What is gel electrophoresis?

Back

Gel electrophoresis is a laboratory method used to separate DNA fragments based on their size.

Front

What is a restriction enzyme?

Back

A restriction enzyme is a protein that cuts DNA at specific sequences, allowing for the manipulation of DNA.

Front

What is ligase?

Back

Ligase is an enzyme that joins DNA fragments together, often used in genetic engineering.

Front

What are genetically modified organisms (GMOs)?

Back

GMOs are organisms whose genetic material has been altered using genetic engineering techniques.

Front

What is the purpose of DNA sequencing?

Back

DNA sequencing determines the exact order of nucleotides in a DNA molecule, which is essential for understanding genetic information.

Front

What is CRISPR technology?

Back

CRISPR is a revolutionary gene-editing technology that allows for precise modifications to DNA in living organisms.

Front

What is the significance of DNA replication?

Back

DNA replication is the process by which a cell makes a copy of its DNA, essential for cell division and inheritance.
