andrew-mc [135]

Answer:

UUAACG

Explanation:

The complementary strand of the DNA strand AATTGC would be UUAACG.

The complementary nucleotide for Guanine [G] will be Cytosine [C] and applies to both DNA and RNA. But the complementary nucleotide for Adenine [A] will be Thymine [T] in DNA and Uracil [U] in RNA.

A codon is a triplet of nucleotides, so it could be any three nucleotides in the strand. Example: AAT, ATT, TTG or TGC.
