What role does recombinant DNA play in genetic engineering?
A
It is used to sequence the entire genome of an organism.
B
It is responsible for the natural mutation of genes.
C
It is used to create identical copies of an organism.
D
It allows for the insertion of foreign genes into an organism's genome.
Verified step by step guidance

Understand the concept of recombinant DNA: Recombinant DNA technology involves combining DNA from different sources to create a new genetic combination. This is a fundamental tool in genetic engineering.
Identify the role of recombinant DNA in genetic engineering: It is primarily used to insert foreign genes into an organism's genome, allowing for the expression of new traits or the production of new proteins.
Differentiate between the options provided: Sequencing a genome involves determining the order of nucleotides, which is not the primary role of recombinant DNA. Natural mutation of genes occurs without human intervention, and creating identical copies of an organism refers to cloning, not recombinant DNA.
Focus on the correct application: Recombinant DNA is used to introduce new genetic material into an organism, which can lead to the expression of desired traits or the production of specific proteins.
Conclude with the correct understanding: The primary role of recombinant DNA in genetic engineering is to allow for the insertion of foreign genes into an organism's genome, enabling the study and manipulation of genetic traits.
