Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Some enzymes, like the ones in your gut, break down large molecules into smaller ones.
Answer: The correct complementary DNA sequence for the given sequence is D. TAG-CAG-GGT.
DNA contains nucleotide pairs on a sugar phosphate backbone. The nucleotide pairs are connected by hydrogen bonds and each nucleotide pairs with only one other nucleotide. The bases are of two types: purine and pyrimidine. The purine bases bond only to pyrimidine bases. The base pairing follows Chargaff’s rule where adenine forms a pair with thymine by two hydrogen bonds and Guanine forms a bond with cytosine with three hydrogen bonds between them.
