The order of amino acids in proteins, which determines their structure and function, is dictated by the genetic code. This code is present in the DNA of every cell. During gene expression, DNA is transcribed into mRNA, which is then translated by ribosomes, along with tRNA molecules that add specific amino acids in the sequence determined by the codons in the mRNA. Each set of three nucleotides in the mRNA, a codon, corresponds to one of the twenty amino acids. Thus, the sequence of nucleotides in the DNA, and hence in the mRNA, directly determines the order of amino acids in a protein. This linear sequence of amino acids then folds into a three-dimensional structure vital for the protein's function. Mutations in the DNA can lead to changes in the amino acid sequence, potentially altering the protein's structure and function, which can result in disease.
The assertion that every protein ends with a specific amino acid is a common misconception. In reality, while every protein starts with the amino acid methionine (in eukaryotes) or a modified form like N-formylmethionine (in prokaryotes), due to the universal start codon AUG, the ending amino acid of proteins can vary widely. This variance is due to the diverse set of stop codons (UAA, UAG, UGA) that do not code for any amino acid but signal the end of the amino acid chain during protein synthesis. Therefore, it's not accurate to say that there's a universal terminal amino acid for all proteins. Instead, the final amino acid is determined by the gene coding for the protein and can be any of the 20 standard amino acids involved in protein synthesis, depending on the sequence.
To prepare screen print emulsion, start by selecting an appropriate emulsion for your screen printing needs; photopolyemulsions are popular for their detail and durability. Ensure your workspace is light-safe since emulsion is light-sensitive. Mix the emulsion according to the manufacturer’s instructions, which typically involve combining the emulsion with a sensitizer. The sensitizer makes the emulsion react to light, so it's crucial to mix it thoroughly to avoid inconsistencies. After mixing, let the emulsion sit for a few minutes to eliminate any air bubbles. Apply the emulsion onto the clean, dry screen using a scoop coater, spreading it evenly across the surface. The thickness of the emulsion layer will affect the printing process, so aim for uniform coverage. Allow the coated screen to dry in a dark, dust-free environment. Once dry, your screen is ready to be exposed to your design under a light source. The unexposed areas can then be washed out, leaving a stencil of your design on the screen ready for printing.
