... and Guanine (G) will only bond to Cystosine (C). For example, a strand of DNA looks like the following: A-A-C-T-G-A-T-A-G-G-T-C-T-A-G Then the DNA strand bound to it would look like: T-T-G-A-C-T-A-T-C-C-A-G-A-T-C Therefore together the section of DNA would be represented as follows: T-T-G-A-C-T-A-T-C-C-A-G-A-T-C A-A-C-T-G-A-T-A-G-G-T-C-T-A-G But ...
