Using both the enzyme reverse transcriptase and radiolabeled deoxynucleotides, you make a radioactive DNA copy from an mRNA. When you hybridize that copy DNA to nuclear DNA, you find that there are seven different chromosomal positions where hybridization occurs, and there are three unhybridized loops at each of the seven positions. From this you conclude:
