Biotechnology (3.3) Review 1

Front

What are restriction enzymes?

Back

Restriction enzymes are proteins that cut DNA at specific sequences, allowing for the manipulation of genetic material in biotechnology.

Front

What is a transgenic organism?

Back

A transgenic organism is an organism that has been genetically modified to contain DNA from another species.

Front

What is the purpose of the Human Genome Project?

Back

The main goal of the Human Genome Project is to sequence all DNA on human chromosomes.

Front

How is human insulin produced using transgenic bacteria?

Back

Transgenic bacteria are engineered to contain the human insulin gene, allowing them to produce insulin that can be harvested and purified for medical use.

Front

What role do plasmids play in genetic engineering?

Back

Plasmids are small, circular DNA molecules used as vectors to transfer genetic material into host cells.

Front

What is recombinant DNA?

Back

Recombinant DNA is DNA that has been artificially formed by combining constituents from different organisms.

Front

What is the significance of bacterial transformation?

Back

Bacterial transformation is a process by which bacteria take up foreign DNA, allowing for genetic modification and the study of gene function.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA.

Front

What is the process of protein isolation?

Back

Protein isolation involves extracting and purifying a specific protein from a mixture, often after it has been produced by transgenic organisms.

Front

What is the role of genetic material in creating a transgenic organism?

Back

Genetic material from one organism is inserted into another organism's genome to confer new traits or abilities.
