Mentally writing in the shower is one of the perks of outlining, because it will get your thoughts percolating. Be sure to keep paper and pens scattered about so you can capture your brilliance the minute it bubbles up, rather than letting all those ideas fade away. This means a finished book in less time!
PCR is used every day to diagnose diseases, identify bacteria and viruses, match criminals to crime scenes, and in many other ways. Step up to the virtual lab bench and see how it works!
What are these things doing in my PCR reaction? Primers are short pieces of DNA that are made in a laboratory. Since they're custom built, primers can have any sequence of nucleotides you'd like.
Through complementary base pairing, one primer attaches to the top strand at one end of your segment of interest, and the other primer attaches to the bottom strand at the other end.
In most cases, 2 primers that are 20 or so nucleotides long will target just one place in the entire genome. Primers are also necessary because DNA polymerase can't attach at just any old place and start copying away. It can only add onto an existing piece of DNA.
DNA Polymerase is a naturally occurring complex of proteins whose function is to copy a cell's DNA before it divides in two. When a DNA polymerase molecule bumps into a primer that's base-paired with a longer piece of DNA, it attaches itself near the end of the primer and starts adding nucleotides.
In nature, these primers are made by an enzyme called primase. Nucleotides are the building blocks that DNA molecules are made of.
DNA polymerase grabs nucleotides that are floating in the liquid around it and attaches them to the end of a primer.Ethics What is Ethics?
