DNA and search for meaning of 7 inches x 3

DNA is found in every living organism. It must also follow the rules of & inches X 3
The video - DNA The Tree of life ( Humanity Hacking Immortality ) explains the following
http://www.youtube.com/watch?v=ZcgfVcuQuW0&feature=related
Three bases of DNA make seven combinations, I can't believe its making sense.
Thymine is the Base for A-DNA and Cytosine the base of B-DNA. Z-DNA is average structure?
Guanine is a Base. Adenine is what?
A always pairs with T in DNA.
C also pairs with G in DNA.
Then the diagram shows ETOH/ Water in both A and C DNA's
Guru Nanak says "Pahla Pani Jiyo Hai, jit hariya sab koi". He also says, "Pani Pita, meaning water is the lifeforce."

I can't read the names of the seven combinations from this diagram in the video clearly.
Now the video slide with purple balls is driving me crazy. I saw purple balls that were filling a space in a circle. These balls were small with each further ball looked bigger than the previous one. I thought it to be a random imagination of my mind. I have seen purple colour in the third eye space before but not lots of minute balls of purple colour that were active.

I don't understand science much. But I am interested in 3' primer and DNA replication.
DNA replication is more accurately described as polymerization. The enzyme which catalyzes this polymerization is called, not surprisingly, DNA polymerase.
Requirement for 3' primer:
Not only are DNA polymerases incapable of polymerizing DNA in the 3' to 5' direction, but they are also incapable of initiating DNA polymerization in the absence of an existing 3' -OH (this has something to do with the DNA polymerases being optimized toward high fidelity sequence duplication---mutation avoidance---rather than high versatility).
This is particularly a problem for the lagging DNA strand since synthesis via Okazaki fragment formation requires repeated initiation of DNA replication de novo.

Note the first slide of this video and count the triangles on the top line only. Seven small triangles have contributed to make an illusion of the three flowers with six petals each. Read the DNA link to see that only one side is DNA and other end of the same is RNA. So for these flowers the top small seven triangles are DNA and the bottom seven would be RNA. After that its all replication. I don't know the consequences in scientific terms, might be none but it does mean special to me. I will keep searching.

Why so many DNA healing videos have used that same slide? Oh, this is called 'Flower of Life'.
