Chapter 13, Problem 10A

Summary Introduction

To fill:

The correct term in the given blank.

Introduction:

Researchers use genetic engineering to manipulate DNA. Biotechnology is the science of using genetic engineering to solve problems. It makes possible to produce organisms that contain individual genes from another organism.

Answer to Problem 10A

Transgenic animals are produced by genetic engineering.

Explanation of Solution

A transgenic organism is one that contains genes from another species. It can be produced by genetic engineering. The process involves cutting or cleaving DNA from one organism into small fragments and then inserting the fragments into a host organism of the same species or different species. Recombinant DNA can also be made by connecting fragments of DNA from different sources. This is inserted into a host organism’s chromosomes. The host organism uses the foreign DNA as if it were its own.

Plants and animals that contain functional recombinant DNA from an organism of different genus are known as transgenic organisms. Example: Glowing tobacco plant contains a gene from a firefly. Transgenic animals like mice, fruit fly, roundworms are produced in labs for research work.
