I also want to believe the inevitable tsunami we call climate change will slow, then stop when and if small nuclear generators work and governments help pay for them, and industry is a...

Each cell has 20,000 sequences of nucleotides called genes.   The order of nucleotide in each tells the ribosome to make a specific chain of amino acids.   MRNA travels to the nucleus, creates a complimentary copy of a gene's nucleotides, and carries the instructions, to the ribosome. The ribosome then creates the appropriate string of amino acids.   After the chain of amino acids is fully formed it “folds”-- changes from an unstable random coil into a three dimensional structure.     If someone could create messenger RNA and deliver it to a cell, they could tell the cell to make a certain protein. Katalin Kariko, the woman who spent her life trying to learn how to control MRNA was born in 1955 in Kisújszállás, a city of 10,000, that was located 100 kilomete...
