Worked Solution & Example Answer:A primary transcript is a strand of A - Scottish Highers Human Biology - Question 2 - 2015
Step 1
C. RNA comprising introns and exons
Answer
The correct answer is C. A primary transcript refers to the initial RNA strand that is synthesized from a DNA template during transcription. This primary transcript contains both introns (non-coding regions) and exons (coding regions). The introns are later removed during RNA processing, leading to the mature mRNA that consists solely of exons.
