Read this paragraph from a passage.

A genetically modified organism is one whose genes have been altered. Genes from one species are inserted into a second
species. The goal of this process is to introduce a desired trait or characteristic into the second species. For example, corn is
vulnerable to certain kinds of worms that eat and destroy the corn stalks. Genes can be taken from some bacteria and inserted
into the corn. These genes from the bacteria enable the corn to produce proteins that kill the worms. This genetically modified
corn is now resistant to these pests. Other plants, such as tomatoes, have been genetically altered in a similar fashion, to remain
fresher longer.
What is the topic sentence of this paragraph?

Final answer:

The topic sentence of the paragraph is "A genetically modified organism is one whose genes have been altered," which introduces the concept of genetically modified organisms and their purpose.

Step-by-step explanation:

The topic sentence of the paragraph provided is: "A genetically modified organism is one whose genes have been altered." This sentence defines a genetically modified organism (GMO) and sets the stage for the rest of the paragraph which explains how genes from one species are inserted into another to introduce desired traits such as pest resistance or prolonged freshness. The paragraph goes on to provide examples of GMOs, namely genetically engineered corn and tomatoes to illustrate these modifications.
