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:

#Unit 3. Fundamental Processes

  1. There are seven copies of the gene for that mRNA and three nontranscribed segments in each gene.

  2. There are seven copies of the gene for that mRNA and three exons in each gene.

  3. There are three copies of the gene for that mRNA and seven exons in each gene.

  4. There are seven copies of the gene for that mRNA and three introns in each gene.
