Explanation:
mRNA is the complement of the DNA template strand. Transcription (process that makes mRNA) requires DNA and nucleotides (A,U,G and C)
The balanced reaction would be:
2 C4H10 + 13 O2 ----> 8 CO2 + 10 H2O
Like this both side of the reaction would have:
8 atoms of C
20 atoms of H
26 atoms of O
Corynebacterium is the answer I believe
