d. All birds and dogs in a ten-kilometer radius of the epicenter went wild
before the earthquake.
5. If scientists can accurately predict earthquakes, there will be
a. Fewer animals going crazy.
b. A lower death rate.
c. Fewer people evacuated.
d. Fewer environmental changes.
Text B. In recent years, scientific and technological developments have
drastically changed human life on our planet, as well as our views both of ourselves
as individuals in society and of the universe as a whole. Maybe one of the most
profound developments in society and of the last decade is the discovery of
recombinant DNA technology, which allows scientists to introduce genetic material
(or genes) from one organism into another. In its simplest form, the technology
requires the isolation of a piece of DNA, either directly from the DNA of the
organism under study, or artificially synthesized from an RNA template, by using a
viral enzyme fragment of bacterial DNA which has the capacity to replicate itself
independently. The recombinant molecule thus produced can be introduced into the
common intestinal bacterium Escherishahia coli, which can be grown in very large
amounts in synthetic media. Under proper conditions, the foreign gene will not only
replicate in the bacteria, but also express itself, through the process of transcription
and translation, to give to large amounts of the specific protein coded by the foreign
gene.
The technology has already been successfully applied to the production of
several therapeutically important biomolecules, such as insulin, interferon, and
growth hormones. Many other important applications are under detailed
investigation in laboratories throughout the world.
1. What is the main idea of the passage?
a. The success of recent DNA technology.
b. The failure of recent DNA technology.
c. The most profound developments of the last decade.
d. Recombinant DNA technology.
2. Recombinant DNA technology consists primarily of
a. Producing several therapeutically important biomolecules.
b. Giving rise to large amounts of protein.
c. Introducing genetic material from one organism into another.
d. Using a viral enzyme called reverse transcriptase.
3. Recombinant DNA technology has been used in the production
of all of the following biomolecules except
a. Growth hormones.
b. Escherishchia coli.
