Answer: Using molecular biology to combine DNA from two different sources in a test tube
Explanation:
Bioinformatics can be defined as a field which involves the information of many fields. These fields are biology, statistics, information engineering and many more.
The bioinformatics also deals with the insilicon drug designing, sequencing, tools for study and research for the more detailed study of DNA. There is no use of wet laboratory techniques in the bioinformatics.
So the correct option is using molecular biology for combining two DNA in test tubes.
