DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

Droplet digital polymerase chain reaction (PCR) measurements of circulating tumor DNA (ctDNA) identify patients with stage III melanoma who are at high risk for early recurrence during adjuvant ...

Me (ME) is bankrupt, its CEO is out, and 15 million people’s genetic data might soon be sold off to whoever’s willing to pay. Now, a swarm ...

(6) Continued exposure to harsh chemicals damages the DNA and reduces yields. Scientists use short oligonucleotides as primers for polymerase chain reaction and next-generation sequencing, in DNA ...

Scientists have taken advantage of the power of DNA polymerase molecules to copy DNA molecules in test tubes via polymerase chain reaction, also known as PCR.

Actually, that's DNA's main purpose ... synthesis is simply to create a polypeptide -- a protein made out of a chain of amino acids. In a hair follicle cell, a protein called keratin is made.

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides ... giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that ...

Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability helps ...
