What is Recombinant DNA?

Back

Recombinant DNA is DNA that has been artificially created by combining DNA from two different sources, such as a plasmid and DNA from another organism.

Front

What is the function of Restriction Enzymes?

Back

Restriction Enzymes are proteins that cut DNA at specific sequences, allowing scientists to manipulate DNA for cloning or analysis.

Front

What is Cas-9?

Back

Cas-9 is a protein that acts as a molecular scissors in gene editing, allowing for precise modifications to DNA.

Front

What does Antiparallel mean in the context of DNA?

Back

Antiparallel refers to the orientation of the two strands of DNA, where one strand runs in the 5' to 3' direction and the other runs in the 3' to 5' direction.

Front

What is Gel Electrophoresis used for?

Back

Gel Electrophoresis is a technique used to separate DNA fragments based on their size, allowing for analysis and comparison.

Front

What is PCR (Polymerase Chain Reaction)?

Back

PCR is a method used to amplify specific DNA sequences, making millions of copies of a particular segment of DNA.

Front

What is Gene Therapy?

Back

Gene Therapy is a technique that modifies or replaces faulty genes to treat or prevent disease.

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 DNA in living organisms?

Back

DNA carries the genetic information necessary for the growth, development, and functioning of all living organisms.

Front

What is a DNA Fingerprint?

Back

A DNA Fingerprint is a unique pattern of DNA sequences that can be used for identification purposes, such as in forensic science.
