Okay so I was in my biology lecture and we were learning about the structure of DNA.
Without boring anyone out there and making this quite short, DNA is composed of a sugar-phosphate backbone and 4 nitrogen base "rungs" which join two strands of sugar-phosphate backbone into a double helix. These are known as Adenine(A), Thymine (T), Guanine (G) and Cytosine (C). A-T stick together, G-C stick together, i.e. base pairs.
In duplicating the genetic code to make new sequences of DNA, the double-helix unzips in between the base pairs and new nitrogen bases come into the unzipped area and form a complementary strand to that of the DNA template. If the DNA template has an A, the new nitrogen base that comes in is a Uracil, rather than a Thymine. If the template had Guanine then a Cytosine molecule would stick to it.
Soooo
if the DNA sequence was: A T G A
it would match with : U A C U
And so what does C A C T correspond to?
G U G A!!!!!!!
Hence dear Gustavo is in our DNA.
