DNA Technology 3.3.3 Practice EOC Questions

Front

What is DNA technology?

Back

DNA technology refers to the methods used to manipulate and analyze DNA, including techniques like cloning, gene therapy, and genetic engineering.

Front

What is cloning in the context of DNA technology?

Back

Cloning is the process of creating a genetically identical copy of an organism or cell, often involving the fusion of gametes.

Front

What are vectors in gene therapy?

Back

Vectors are vehicles used to deliver genetic material into cells; common vectors include viruses.

Front

What is gene therapy?

Back

Gene therapy is a technique that uses genetic engineering to treat or prevent diseases caused by genetic defects.

Front

What is the diploid chromosome number?

Back

The diploid chromosome number is the total number of chromosomes in a cell, representing two sets of chromosomes, one from each parent.

Front

What is the role of viruses in gene therapy?

Back

Viruses are often used as vectors in gene therapy to carry healthy genes into human cells to correct genetic disorders.

Front

What is recombinant DNA technology?

Back

Recombinant DNA technology involves combining DNA from different sources to create new genetic combinations for research or therapeutic purposes.

Front

What is the difference between mitotic and meiotic cell division?

Back

Mitotic cell division results in two identical daughter cells, while meiotic cell division produces four genetically diverse gametes.

Front

What is the significance of stem cell therapy?

Back

Stem cell therapy involves using stem cells to treat or prevent diseases, particularly those related to damaged tissues or organs.

Front

What is a genetic defect?

Back

A genetic defect is a mutation or alteration in DNA that can lead to diseases or disorders.
