DNA digital data storage is the process of encoding and decoding binary data to and from synthesized strands of DNA. [1] [2]While DNA as a storage medium has enormous potential because of its high storage density, its practical use is currently severely limited because of its high cost and very slow read and write times.
WhatsApp will now let you record and send video clips directly in the messaging app, the Meta-owned platform announced this week. The instant video messages can be up to 60 seconds long, and are ...
It allows users to send text, voice messages and video messages, [14] make voice and video calls, and share images, documents, user locations, and other content. [15] [16] WhatsApp's client application runs on mobile devices, and can be accessed from computers. [17] The service requires a cellular mobile telephone number to sign up. [18]
WhatsApp's user base swells to about 200 million active users and its staff to 50. [2] 2013: July: Funding: Sequoia invests another $50 million in Series B round, valuing WhatsApp at $1.5 billion. [9] 2013: July 16: Product: WhatsApp goes free, with an annual subscription fee of $1 after the first year. [10] [11] 2013: August: Competition
The biocompatible computing device: Deoxyribonucleic acid (DNA) DNA computing is an emerging branch of unconventional computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional electronic computing. Research and development in this area concerns theory, experiments, and applications of DNA computing.
DNA sequencing may be used along with DNA profiling methods for forensic identification [21] and paternity testing. DNA testing has evolved tremendously in the last few decades to ultimately link a DNA print to what is under investigation. The DNA patterns in fingerprint, saliva, hair follicles, etc. uniquely separate each living organism from ...
A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.
Only a few years after James Watson and Francis Crick deduced the structure of DNA, and nearly two decades before Frederick Sanger published the first method for rapid DNA sequencing, Richard Feynman, an American physicist, envisioned the electron microscope as the tool that would one day allow biologists to "see the order of bases in the DNA chain".
