Detailed explanation-1: -The if given the base sequence for one strand: 5’-AGGTCCG-3’, the complimentary strand must have the sequence: 3’-TCCAGGC-5’.
Detailed explanation-2: -DNA is always synthesized in the 5’-to-3’ direction, meaning that nucleotides are added only to the 3’ end of the growing strand. As shown in Figure 2, the 5’-phosphate group of the new nucleotide binds to the 3’-OH group of the last nucleotide of the growing strand.
Detailed explanation-3: -Nucleic acid base sequences that can form a double-stranded structure by matching base pairs; the complementary sequence to G-T-A-C is C-A-T-G.
Detailed explanation-4: -The coding strand is directed in the 3’ to 5’ direction. The template strand is directed in the 5’ to 3’ direction. The coding strand has a complementary nucleotide sequence.
