Final answer:
True, data transformation generally involves mapping data from a source to a target and performing required transformations to achieve mapped results, but the provided context about DNA is unrelated to computing data transformation.
Step-by-step explanation:
True, in general, data transformation involves mapping data from a source to a target and performing transformations on that data required to achieve the intended mapped results. Data transformation can be applied in various sectors, including business intelligence, data warehousing, and software development. However, the provided transformation example which states that it is a process in which external DNA is taken up by a cell, thereby changing morphology and physiology, is not a description of data transformation in a computing context; instead, it refers to a biological process.
