More on the "and" and the "or" at a cellular level

From our last post, we see how the repetition of relatively few elements into various sequences can result in incredible diversity.  The study of cellular DNA also reveals that cells have various lengthy sequences of nucleotide bases, and these sequences repeat themselves thousands of times.  It is not currently known what funcion, if any, these sequences have.   However, it is known that the "or" limits the degree of repetition somewhat when transcribing DNA to make proteins.   Apparently, after messenger RNA is formed, before it can be read, spliceasomes splice up this RNA, cutting out various portions thereof and then putting it back together.   T-RNA then attaches itself to this mRNA, and to the end of this t-rna, an amino acid is attached.  It seems that these amino acids are able to slip outside the nucleus of the cell, and a ribosme takes these amino acids and constructs a protein.  Why all these steps are necessary is not clear. It is possible that some of the useless DNA was deposited by viruses.  Retroviruses themselves take advantage of the "and" to replicate and insert their DNA into chromosomes.   The "or", namely the transcription process, then splices away some of these sequences, or so it seems.

While the "or" takes advantage of the repetition of the "and" to create diversity, in the form of thousands of genes, proteins, enzymes and the like, the "and" also prospers when cells reproduce.  We see the "and"'s expressions on a macro level when we note that virtually every cell has the same DNA, the same endless sequences of nucleotide bases.
