Chapter 8, Problem 1
Which of the following statements is true concerning recombinant DNA technology?
a. It will replace biotechnology in the future.
b. It is a single technique for genetic manipulation.
c. It is useful in manipulating genotypes but not phenotypes.
d. It involves modification of an organism’s genome.
Verified step by step guidance1
Step 1: Understand the definition of recombinant DNA technology. It refers to the process of combining DNA from different sources to create new genetic combinations that are of value in research, medicine, agriculture, and industry.
Step 2: Analyze option (a): 'It will replace biotechnology in the future.' Biotechnology is a broad field that includes recombinant DNA technology as one of its tools, so recombinant DNA technology cannot replace the entire field of biotechnology.
Step 3: Analyze option (b): 'It is a single technique for genetic manipulation.' Recombinant DNA technology encompasses multiple techniques such as cloning, gene splicing, and transformation, so it is not just a single technique.
Step 4: Analyze option (c): 'It is useful in manipulating genotypes but not phenotypes.' Since changes in genotype often lead to changes in phenotype, recombinant DNA technology can affect both genotype and phenotype.
Step 5: Analyze option (d): 'It involves modification of an organism’s genome.' This is true because recombinant DNA technology directly modifies the genetic material of an organism to introduce new traits or functions.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Recombinant DNA Technology
Recombinant DNA technology involves combining DNA from different sources to create new genetic combinations. It allows scientists to modify an organism’s genome by inserting, deleting, or altering specific genes, enabling targeted genetic manipulation.

Relationship Between Genotype and Phenotype
Genotype refers to the genetic makeup of an organism, while phenotype is the observable traits resulting from gene expression. Changes in genotype through recombinant DNA technology can lead to altered phenotypes, demonstrating the technology’s impact beyond just genetic sequences.

Scope of Biotechnology vs. Recombinant DNA Technology
Biotechnology is a broad field encompassing various techniques that use living organisms for practical purposes, including recombinant DNA technology. Recombinant DNA is one of many tools within biotechnology, not a replacement for the entire field.
