What is genetic engineering?

Back

Genetic engineering is the direct manipulation of an organism's genes using biotechnology to alter its characteristics.

Front

What is selective breeding?

Back

Selective breeding is a process used to develop new organisms with desirable traits by choosing specific parents.

Front

What is CRISPR?

Back

CRISPR is a revolutionary gene-editing technology that allows for precise, faster, and cheaper modifications to DNA.

Front

What is gel electrophoresis used for?

Back

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

Front

Why do DNA fragments move in gel electrophoresis?

Back

DNA fragments move towards the positive electrode because DNA is negatively charged.

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 gene therapy?

Back

Gene therapy aims to treat or prevent diseases by inserting, altering, or removing genes within an individual's cells.

Front

What is a plasmid?

Back

A plasmid is a small, circular piece of DNA found in bacteria that can replicate independently and is often used in genetic engineering.

Front

What is the role of restriction enzymes in genetic engineering?

Back

Restriction enzymes cut DNA at specific sequences, allowing scientists to manipulate genes.

Front

What is the significance of the Human Genome Project?

Back

The Human Genome Project was an international research effort to sequence and map all the genes of the human species.
