Answer:
The primary mRNA transcript is the RNA molecule synthesized by the process of translation.
The primary transcript is the processed form of the RNA molecule which does not contain any non-coding sequence called "introns" that is they contain only coding sequences. The transcript molecule also contains cap and tails at the 5 ' end and 3' end respectively which protect it from the attacks of enzymes and helps in the process translation.
Thus, the primary mRNA transcript is the mature form of the RNA molecule which is single-stranded.
