What is Genetic Technology?

Back

Genetic technology refers to the techniques used to manipulate DNA and genes to alter the genetic makeup of organisms, which can include cloning, gene editing, and genetic engineering.

What is DNA electrophoresis?

Back

DNA electrophoresis is a laboratory technique used to separate DNA fragments based on their size by applying an electric field to a gel matrix.

What is a transgenic organism?

Back

A transgenic organism is one that has been genetically modified to contain a gene or genes from another species.

What is the purpose of restriction enzymes in genetic technology?

Back

Restriction enzymes are used to cut DNA at specific sequences, allowing scientists to manipulate and analyze genetic material.

What was the significance of Dolly the Sheep?

Back

Dolly the Sheep was the first mammal to be cloned from an adult somatic cell, demonstrating that specialized cells could be reprogrammed to develop into a new organism.

Front

What is gene therapy?

Back

Gene therapy is a technique that modifies a person's genes to treat or prevent disease, often by inserting a healthy gene to replace a defective one.

Front

What are plasmids?

Back

Plasmids are small, circular DNA molecules found in bacteria that can replicate independently and are often used as vectors in genetic engineering.

Front

What is CRISPR technology?

Back

CRISPR is a revolutionary gene-editing technology that allows for precise modifications to DNA, enabling targeted changes in the genome.

Front

What is the role of genetic markers?

Back

Genetic markers are specific sequences in the genome that can be used to identify individuals or species and track inheritance patterns.

Front

What is cloning?

Back

Cloning is the process of creating a genetically identical copy of an organism or cell.
