Note that this is a specific application of de novo DNA synthesis, e.g. polymerase chain reaction primers is another major application that does not imply creating genes.
Using de novo DNA synthesis to synthesize entire Chromosomes.
Synthesizing the DNA itself is not the only problem however.
You then have to get that DNA into a working living form state so that normal cell processes can continue:
Multicellular questions:
Apparently achieved for the first time in 2021: www.jcvi.org/research/first-self-replicating-synthetic-bacterial-cell by the J. Craig Venter Institute.
Man-made virus!
TODO: if we had cheap de novo DNA synthesis, how hard would it be to bootstrap a virus culture from that? github.com/cirosantilli/cirosantilli.github.io/issues/60
Is it easy to transfect a cell with the synthesized DNA, and get it to generate full infectious viral particles?
If so, then de novo DNA synthesis would be very similar to 3D printed guns: en.wikipedia.org/wiki/3D_printed_firearms.
It might already be possible to order dissimulated sequences online:
Incredible that there hasn't been a Nobel Prize for it as of 2022, e.g. as mentioned at: theconversation.com/no-nobel-but-epigenetics-finally-gets-the-recognition-it-deserves-18970

Nihonium is a synthetic chemical element with the symbol Nh and atomic number 113. It is one of the superheavy elements in the periodic table and was first officially reported in 2004 by a team of Japanese scientists at the RIKEN institute. The name "Nihonium" is derived from "Nihon," which is one of the ways to say "Japan" in Japanese, reflecting the element's discovery in Japan.
Taqi ad-Din Muhammad ibn Ma'ruf, often referred to simply as Taqi ad-Din, was a prominent Arab astronomer, mathematician, and engineer during the 16th century. He was born in 1526 in Damascus in the Ottoman Empire (modern-day Syria). He is best known for his contributions to astronomy and for establishing the first observatory in the Islamic world, the Maragha Observatory, which played a pivotal role in the development of astronomical research.
The Pearson distribution, or Pearson system of distributions, is a family of continuous probability distributions that are defined based on moments, especially how the shape of the distribution is determined by its moments (mean, variance, skewness, and kurtosis). This system was introduced by Karl Pearson in the early 20th century, and it encompasses a wide range of probability distributions, including the normal distribution, beta distribution, and skewed distributions.
Data-Link Switching (DLSw) is a networking protocol that helps in the interconnection of different types of network protocols, specifically to facilitate the transmission of data over WAN (Wide Area Network) links. It was primarily developed to enable the encapsulation and transport of legacy protocols, such as IBM's SNA (Systems Network Architecture), over TCP/IP networks.
Edward H. Sussenguth was a renowned American marine biologist, particularly recognized for his work in the field of ichthyology, the study of fish. He significantly contributed to our understanding of fish taxonomy and ecology, particularly in the Atlantic Ocean. Sussenguth's research included extensive studies on the life histories and populational dynamics of various fish species. His work is important for both academic research and practical applications in fisheries management and conservation.
IBM DISOSS, or IBM Dynamic Infrastructure Services for Open Systems Software, is a set of software and tools designed to help organizations manage and optimize their IT infrastructure. It focuses on improving the performance, security, and scalability of systems, particularly in dynamic and virtualized environments. DISOSS enables better resource management, automates tasks, and enhances the overall efficiency of IT operations, supporting both traditional and cloud-based architectures.
Synchronous Data Link Control (SDLC) is a bit-oriented synchronous communication protocol used for transmitting data over point-to-point and multipoint links. It was developed by IBM in the 1970s as a way to facilitate reliable and efficient data transmission in telecommunications. ### Key Features of SDLC: 1. **Synchronous Communication**: SDLC operates synchronously, meaning that data is transmitted in a continuous stream along with a clock signal.
As of my last knowledge update in October 2023, Narayanan Chandrakumar does not appear to be a widely recognized figure in public records or notable databases. It’s possible that he could be an emerging public figure, a private individual, or associated with a specific academic, professional, or cultural context that is not broadly documented.
A **quantile-parameterized distribution** is a type of probability distribution that is characterized directly in terms of its quantiles, rather than through its probability density function (PDF) or cumulative distribution function (CDF). This approach emphasizes the distribution's quantile function, which provides a way to describe the distribution based on the values at specified probabilities.
Sweden primarily uses the metric system for measurements, which is standard in most countries around the world except for a few like the United States. Here are some of the common units of measurement used in Sweden: 1. **Length**: - Meter (m) - Centimeter (cm) - Millimeter (mm) - Kilometer (km) 2.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
