You are running a transcription reaction in your lab. You stop the reaction after a few minutes, and you find that you have three predominant DNA and RNA molecules in your test tube. All have different lengths. The first molecule is 300 nucleotides long, the second is 25 nucleotides long, and the third is 40 nucleotides long. Which molecule is likely the pre-mRNA

16. which of the following accurately describes a step within transcription? a. dna polymerase uses one strand of rna as a template to put together nucleotides. b. the dna strand is used as a template for which a complementary rna strand can be produced. c. the rna strand forms a template by which dna can be built. d. the rna strand is produced within the cytoplasm.
