Final answer:
The strand of DNA used for transcription is known as the template strand, while the other strand that remains untranscribed is called the nontemplate or coding strand.
Step-by-step explanation:
The nucleotide strand used for transcription is termed the template strand, whereas the non-transcribed strand is called the nontemplate strand or coding strand.
During transcription, RNA polymerase creates an RNA sequence that is complementary to the template strand and almost identical to the coding strand with the exception that uracil (U) is used in place of thymine (T) found in DNA.
