You are provided with a sample of aardvark DNA. As part of your investigation of this DNA, you transcribe mRNA from the DNA and purify it. You then separate the two strands of the DNA and analyze the base composition of each strand and of the mRNA transcripts. You obtain the following results:                                A        G         C         T          UDNA strand #1      19.1    26.0     31.0     23.9      0DNA strand #1      24.2    30.8     25.7     19.3      0mRNA                   19.0     25.9    30.8        0       24.3Which strand of the DNA is the “sense” strand that serves as the template for mRNA synthesis?

Question

You are provided with a sample of aardvark DNA. As part of your investigation of this DNA, you transcribe mRNA from the DNA and purify it. You then separate the two strands of the DNA and analyze the base composition of each strand and of the mRNA transcripts. You obtain the following results:
                                A        G         C         T          U
DNA strand #1      19.1    26.0     31.0     23.9      0
DNA strand #1      24.2    30.8     25.7     19.3      0
mRNA                   19.0     25.9    30.8        0       24.3
Which strand of the DNA is the “sense” strand that serves as the template for mRNA synthesis?
