If a DNA strand has the nucleotide sequence of CCGAGATTG, what is the nucleotide sequence of the complementary strand?

GGCTCTAAC

When translating a strand of DNA, remember the following: G translates into C, C translates into G A translates into T, T translates into A

The translation between A and T has an exception when you translate to RNA: T becaumes U, so A translates to U and when you translate from RNA to DNA then U translates to A.
