Molecular Xeroxing......

a: Pcr ~
b: photocopying regions of DNA

What: "Put simply, PCR is like photocopying regions of DNA" or as another website put it "PCR is like looking for a needle in a haystack, and then making a haystack out of the needle"

Searching And Replicating

a: Pcr ~
b: computer +photocopier

What: From:"Pandora's Picnic Basket : The Potential and Hazards of Genetically Modified Foods" in the book is makes this compariosn "Conceptually, PCR is like taking a computer with search capability and hooking it up to a photocopier."

A Very Accurate And Powerful Detector

a: Pcr ~
b: using a very powerful microscope

What: "Using PCR is like using a very powerful microscope," Lynch said. "It's more sensitive than X-ray imaging. We're using PCR as a way to look at minute levels of residual cancer cells -- malignancy that remains after treatment is concluded. We're using PCR to analyze blood and bone marrow and to correlate our findings with what we see with X-ray images."

Copying....

a: Pcr ~
b: a photocopier that makes photocopiers

What: PCR can selectively replicate DNA. It does this by making a copy of a DNA strand. 1 DNA-->2DNA; 2DNA-->4; 4DNA--> 8DNA; and so on. The photocopier analogy is close, but doesn't describe why the copying is so efficient. Each new DNA strand becomes a template for another new strand of DNA.

a: qPCR ~
b: copy machine with a counter

What:

"In essence, qPCR is like a copy machine with a counter. The "primers" select which pages (target) of the book (DNA) are copied and the counter keeps a running total of how many pages were copied (number of target genes in the sample)."

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.
