Yоu оbtаin а sаmple оf double-stranded DNA and transcribe mRNA from this DNA.  You then analyze the base composition of each of the two DNA strands and the one mRNA strand, and get the following results.  The numbers indicate the percentage of each base in the strand:   Composition of Samples   A G C T U STRAND #1 40.1 28.9 9.9 0.0 21.1 STRAND #2 21.5 9.5 29.9 39.1 0.0 STRAND #3 40.0 29.0 9.7 21.3 0.0   Which of these strands must be the mRNA? Briefly explain your answer using the information from the table above and your knowledge of RNA and transcription. Which one is the template strand for the mRNA? Briefly explain your answer using the information from the table above and your knowledge of RNA and transcription.
