Final answer:
DNA is transcribed into RNA during the process of transcription, which is performed by the enzyme RNA polymerase.
Step-by-step explanation:
The answer to the student's question 'DNA is ________ RNA' is c) Transcribed. The process known as transcription involves the enzymatic synthesis of an RNA strand that has a sequence complementary to the DNA. In this process, the segment of DNA that is copied into RNA is called a gene, and this is done by the enzyme RNA polymerase. This step is crucial as it dictates what proteins will be produced by the cell during the process of translation, where RNA is used as a template to synthesize proteins. Proper transcription is vital, as errors can lead to various hereditary and age-related diseases.
