Molecular Technologies Using DNA

Front

What is molecular technology?

Back

Molecular technology refers to techniques and methods used to manipulate and analyze biological molecules, such as DNA, RNA, and proteins, for various applications in fields like medicine, agriculture, and research.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is a method used to separate DNA, RNA, or proteins based on their size and charge.

Front

What do longer bands in gel electrophoresis represent?

Back

Longer bands represent larger molecules.

Front

What do shorter bands in gel electrophoresis indicate?

Back

Shorter bands indicate smaller molecules.

Front

Name one application of molecular technologies in medicine.

Back

Molecular technologies are used in medicine for genetic testing, gene therapy, and the development of vaccines.

Front

How does gel electrophoresis work?

Back

Gel electrophoresis works by applying an electric current to a gel matrix, causing charged molecules to migrate through the gel. Smaller molecules move faster and farther than larger ones.

Front

What is the role of DNA in molecular technologies?

Back

DNA serves as the primary genetic material that can be manipulated for cloning, sequencing, and genetic engineering.

Front

What is the significance of separating molecules in molecular biology?

Back

Separating molecules allows scientists to analyze their size, purity, and function, which is crucial for research and diagnostics.

Front

What is a common use of molecular technologies in agriculture?

Back

Molecular technologies are used in agriculture for developing genetically modified organisms (GMOs) that are resistant to pests and diseases.

Front

What is the purpose of using markers in gel electrophoresis?

Back

Markers are used as reference points to determine the size of the separated molecules.
