The sugar-phosphate backbone has the phosphates as the backbone with the ribose sugars as the attachments (connections) to the [C or G or A or T] nucleotides.
DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G). A and T are connected by two hydrogen bonds. G and C are connected by three hydrogen bonds.

A = Adenine (Blue) T = Thymine (Yellow) G = Guanine (Green) C = Cytosine (Red) Backbone atoms = (Purple)
The four nitrogenous bases are A (adenine), C (cytosine), G (guanine) and T (thymine) in DNA. They are bonded to the deoxyribose in the sugar-phosphate backbone at the 1' position.
The other side is TGCGAA. This is because A always binds with T and C always binds with G since DNA strands that are connected together are always complimentary.

DNA is double helical in structure. each spiral strand, composed of a sugar phosphate backbone and attached bases, is connected to a complementary strand by hydrogen bonding (non- covalent) between paired bases, adenine (A) with thymine (T) and guanine (G) with cytosine (C).
If a DNA strand read CCTAGCT, its mRNA would read GGAUCGA.

DNA has A-T and C-G while RNA has A-U and C-G
In DNA, A binds to T and C binds to G Therefore the complementary DNA sequence to 5'-GAT-CGG-TAC-AGT-G-3' is: 3'-CTA-GCC-ATG-TCA-C-5'
on the outside of the DNA strand is the phosphate and sugar, only the sugar are connected across to the other half with the A&T and C&G
