Question

What is the mRNA sequence for a strand of DNA reading ccgtact

Answer 1

CCGTACT 
        =
GGCATGA

I believe because C = G , G = C , T = A , and A = T

Answer 2

RNA does not contain T (thymine). It contains U (uracil) instead. So,
A is complementary to U
C is complementary to G
G is complementary to C
T is complementary to A
The answer is
GGCAUGA
