"Sound evidence points to the theory that RNA is the first living molecule. RNA is good at copying itself and it carries a lot of information in its structure. In today's cell, RNA acts as a sort of office messenger. If DNA is the master architect, RNA is like an assistant who takes a blueprint from DNA and plugs it into cellular machines. (These machines, called ribosomes, are actually made up of RNA as well.) These ribosomes read the blueprint like a set of instructions that tell which amino acids to hook together."
"A codon is a set of three
RNA nucleotides that have the information for the addition
of a specific amino acid. So
the tRNA is like the translator that translates the message from RNA code into a protein."
There are many associations for trna floating around in the the binary sea that is the internet. The trna is a macro molecule that specifies that a given mrna codon is translated into a specific amino acid. Literally it is a linking molecule that contains a particular activated amino acid on 1 end and specific RNA sequence on the other. TRNAs span 2 molecular worlds. The world of macromolecules made of nucleotides with the world of macro molecules made of amino acids.
"The secondary structure of rRNA is like flower, containing many stem-loop structure."
"rRNA is like a translator, it reads the mRNA and tells the ribosomes how to make proteins "
"The siRNA is like a gear: On its own, not much there. But it's not impossible to imagine that it could become part of a larger system."
"seems like miRNA is like the quantum-mechanics of biology, anything too complex and i bet sooner or later you will see a paper relating it to miRNA"
"The scientist uses several copies of another bit of RNA called a primer. A primer is like a mirror image of a short bit of RNA or single strand of DNA; that is, its sequence of nucleotides is the direct complement to the sequence of nucleotides in a known part of the target RNA or DNA."
for example, removing vegetables from our fried rice.
"No primer is used (RNA polymerase is like 2 in one paint and primer). RNA is made in the 5' to 3' direction (like DNA)."
"Using the analogy of a car; DNA analysis allows you to put your ear up against its hood to hear what is happening in the engine, and RNA processing is like opening the hood and being able to see the engine itself."
"The mRNA vaccine provides instructions to your body on how to build the response to the virus. If a traditional vaccine shows you a car, and you get to figure out how to build the car by seeing it, the mRNA vaccine is like providing the actual blueprints and factory to build it."
"Tom Freiden, former director of the US Center for Disease Control and Prevention (CDC), makes an analogy: "an mRNA vaccine is like an email sent to the immune system that shows what the virus is like and gives instructions to kill it and then , like a Snapchat message, disappears. ""
"It has often been noted that the distribution of RNA polymerase between different promoters in rapidly growing E. coli is like the distribution of wealth between the people in western democracies!"
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
