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 ...

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific ...

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 ...

Blockchain advocates hope 23andMe’s bankruptcy will serve as a wake-up call regarding the need for decentralization.

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.

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 ...

PCR, or Polymerase Chain Reaction, is a revolutionary molecular biology technique that allows for the rapid amplification of specific DNA sequences. It is an essential tool in various fields, ...

(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 ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
