Below are some strands of DNA. Only one strand is shown. Create the complementary strands. I have broken the strand
into pieces of 3 nucleotides to make it easier to read.
1. ATA / CGA / TCG / ATC / GAT / TTT / CAG / TCA / GTT / CAA
2. CAT / CAT / ATA / CCC / AAA / CAA / CTT / GGC / GGA / AGG
3. AAA / CAC / GGT / GAA / CGG / GGG / ATG / GAA / TGA / GGC
4. GGTTACTAGCATCAACAGGGGTGACATTTTCAAAACC
5. AAGCATCAGTCATGCATGCGTAGCTTTTGCATGGCTTGACTG
