Assertion: In eukaryotes, the sequence of nucleotides of mRNA is same as that of template except for the difference of T and U.
Reason: In eukaryotes antisense strand is complementary to sense strand and mRNA is complementary to coding strand.
Reason: In eukaryotes antisense strand is complementary to sense strand and mRNA is complementary to coding strand.
