The DNA Replication Complex, an assembly of proteins that synthesizes new DNA before cell division.  It consists of Helicase, Primase, Single-strand binding proteins, and DNA polymerase III.  Because DNA strands can only be copied in one direction, the complex must pull out loops of one strand and replicate it in fragments.  At this moment there are hundreds of trillions of these molecular machines in constant activity within your body.

be sure to check out Drew Berry’s full DNA animation here, it will rock your genetic socks off. He also gave a fine TED talk about how he animates the unseeable world of biology.

In humans, this process is happening at the staggering speed of 3,000 DNA bases per minute. And in bacteria? Would you believe 30,000 bases per minute?!? That’s 500 nucleotides per second!!!

while this is mostly about facts, there are a lot of opinions in this tutorial (namely my distrust on several brands marketing strategies, and my opinion that’s better to start with cheap student quality stuff. LOTS of people disagree on that point) as well that you should take as what they are: personal opinions.

here is slightly more readable than on tumblr

this is the result of several years of research on creating a cheap but high quality palette that would help me.

other things to be aware of: pigments are generally more resistant in oil and acrylics than they are in watercolor. but there are a couple of pigments that work well in watercolor but really badly in oil.

resources pigments through the ages a comprehensive guide to watercolor pigments and a lot of tests on popular brands about van gogh’s bedroom Blue and Yellow don’t make green by Michael Wilcox

Very good infographic!

I would like to add the Daniel Smith brand to that tiny chart in the third image. They can be a little hard to find save ordering them from Daniel Smith, but they have a lot of really unusual and unique pigments in their artist quality watercolor collection, including interference paints and other cool shit. These are what I use, save a few W&N Cotman colors I haven’t replaced yet.

Just reblogging this because apparently it’s going around a lot again. I would like to point out that while Daniel smith is indeed a decent brand it’s pretty much the same as all the others, meaning: it has its shadowy things as well. Daniel smith in particular has the tendency to abuse the ‘romantic’ names and it’s pretty unclear with its marketing, always masking their pigments with misleading names such as ‘lunar red rock’. And also sells pigments that are notably untrustworthy, such as rose madder PR60. If you read the lightfastness note at the bottom of the page they actually tells you it’s volatile (meaning: it becomes white after a while) but still, if you don’t check (and you don’t know what they mean for ‘volatile’) you’ve just paid 20 bucks for something that won’t last.

The point still stands: always check before buying. if someone recommend some brand DON’T TRUST IT BLINDLY.

All the best brands, winsor& newton, Maimeri, Daler&Rowney, Daniel Smith, Holbein…. they are all extremely good with their paints but they all have that couple of colors in their charts that ought not to be trusted.

Grand Juror Sues McCulloch, Says He Mischaracterized The Wilson Case
By CHRIS MCDANIEL
A grand juror is suing St. Louis County Prosecutor Bob McCulloch in an effort to speak out on what happened in the Darren Wilson case. Under typical circumstances, grand jurors are prohibited by law from discussing cases they were involved in.
The grand juror, referred to only as “Grand Juror Doe” in the lawsuit, takes issue with how McCulloch characterized the case. McCulloch released evidence presented to the grand jury and publicly discussed the case after the grand jury decided not to indict Wilson, then a Ferguson police officer, in the shooting death of Michael Brown, an 18-year-old African American.
“In [the grand juror]’s view, the current information available about the grand jurors’ views is not entirely accurate — especially the implication that all grand jurors believed that there was no support for any charges,” the lawsuit says. “Moreover, the public characterization of the grand jurors’ view of witnesses and evidence does not accord with [Doe]’s own.”
“From [the grand juror]’s perspective, the investigation of Wilson had a stronger focus on the victim than in other cases presented to the grand jury,” the lawsuit states. Doe also believes the legal standards were conveyed in a “muddled” and “untimely” manner to the grand jury.
In the lawsuit filed Monday in federal court, the American Civil Liberties Union of Missouri argues that this case is unique and that the usual reasons for requiring the jurors to maintain secrecy should not apply.
In this specific case, “any interests furthered by maintaining grand jury secrecy are outweighed by the interests secured by the First Amendment,” the lawsuit says, adding that allowing the juror to speak would contribute to a discussion on race in America.
As the grand juror points out in the lawsuit, the Wilson case was handled in a very different manner than other grand juries. Instead of recommending a charge, McCulloch’s office presented thousands of pages worth of evidence and testimony before the grand jury. At one point, McCulloch’s spokesman characterized the grand jury as co-investigators.
“From [Doe]’s perspective, although the release of a large number of records provides an appearance of transparency, with heavy redactions and the absence of context, those records do not fully portray the proceedings before the grand jury,” the lawsuit says.
McCulloch has done several interviews since the grand jury decision was announced on Nov. 24, but the grand jurors have been prohibited from speaking about the case. The county prosecutor admits that some of the witnesses were lying, but said the grand jurors were aware.
The 12 people who could say for sure are currently sworn to secrecy.
Although the county released redacted transcripts of witness and expert testimony, the grand jurors deliberated without a court reporter or member of the prosecutor’s office present.

The level of incompetency and flat out misconduct by Bob McCulloch is both baffling and disturbing. Hopefully this renews the call for a special prosecutor in the case against Darren Wilson for the murder of Mike Brown. #staywoke #farfromover
