Can anyone explain how you can store the information in DNA?
I know there are possibilities to alter DNA by crossing, which is done with plants and animals.
But completely new information? Would like to know.
As well, if it is possible to alter DNA, it should be possible to fix about anything, from eye, skin, hair color to implementing superpowers (add some
of Usain Bolts DNA for speed, mix a bit of tibetan DNA for high concentration of red blood cells, etc) , or am i wrong on this?
I know they use viruses to alter DNA in research situations (probably not all the time, but I'm not an expert).
A virus isn't alive. It's a capsid with a fragment of DNA inside and "sites" that are a specific shape to fit a similar shape like a puzzle piece
on a specific type of cell (e.g. a skin cell). When the virus latches onto a skin cell it "injects" the DNA fragment into the host cell. This host
cell now manufactures whatever the DNA tells it to. In the "wild" the host cell would now construct more viruses to alter more cells, in research
they can use the virus to inject whatever they want it to into the cells.
I don't really know how they store information in DNA, but it would probably just be encoded like other simple codes.
For example, the base pairs that make up DNA are adenine, guanine, cytosine, and tyrosene or A,G,C,T. Now, DNA is made up of pairs of these
nucleotides or base pairs. A always goes with G and C always goes with T. The DNA is just a long string of these nucleotides (only one of the pairs
is usually written for brevity). A certain sequence of base pairs codes for different proteins in the body. For example, a stop codon, or sequence
that indicates the end of a protein might be (is? I'm going from memory) CATGTATAC. I Could see you being able to use this to just make words. A
might be the letter "A". AA might be the letter "B" and AAC might indicate a space or a period. You could just encode whatever you wanted to
I don't know the method by which they "construct" DNA.
