The complementary strand is
T-A-G-C-G-G-A-A-T-C-T-T-A-C-C (if by F you meant G)
but you should always write it from 5´to 3´, therefore is
C-C-A-T-T-C-T-A-A-G-G-C-G-A-T

Each type of base on one strand forms a bond with just one type of base on the other strand. This is called complementary base pairing. Here, purines form hydrogen bonds to pyrimidines, with A bonding only to T, and C bonding only to G. This arrangement of two nucleotides joined together across the double helix is called a base pair. In a double helix, the two strands are also held together by forces generated by the hydrophobic effect and pi stacking, but these forces are not affected by the sequence of the DNA. As hydrogen bonds are not covalent, they can be broken and rejoined relatively easily. The two strands of DNA in a double helix can therefore be pulled apart like a zipper, either by a mechanical force or high temperature. As a result of this complementarity, all the information in the double-stranded sequence of a DNA helix is duplicated on each strand, which is vital in DNA replication. Indeed, this reversible and specific interaction between complementary base pairs is critical for all the functions of DNA in living organisms.
The two types of base pairs form different numbers of hydrogen bonds, AT forming two hydrogen bonds, and GC forming three hydrogen bonds (see figures, left). The GC base pair is therefore stronger than the AT base pair. As a result, it is both the percentage of GC base pairs and the overall length of a DNA double helix that determine the strength of the association between the two strands of DNA. Long DNA helices with a high GC content have strongly interacting strands, while short helices with high AT content have weakly interacting strands. Parts of the DNA double helix that need to separate easily, such as the TATAAT Pribnow box in bacterial promoters, tend to have sequences with a high AT content, making the strands easier to pull apart. In the laboratory, the strength of this interaction can be measured by finding the temperature required to break the hydrogen bonds, their melting temperature (also called Tm value). When all the base pairs in a DNA double helix melt, the strands separate and exist in solution as two entirely independent molecules. These single-stranded DNA molecules have no single shape, but some conformations are more stable than others. The base pairing, or lack of it, can create various topologies at the DNA

The sharps are one fret up from the natural note. For instance, if you're playing a C on the 3rd fret, the C sharp is the fourth fret. The flat is one fret down. But if you're talking about chords, I really can't help you.

TAGCGGAATCTTA?C There isn't an F, so check that one.
I teach my students that straight letters go with straight letters AT. Round letters with round letters CG.

T-A-G-C-G-G-A-A-T-C-T-T-A- WHERE DID F AND G COME FROM? THERE ARE NO NUCLEOTIDES EITHER IN DNA OR RNA!
