DNA survives a ride into spaceon the exterior of a …

Posted: at 11:44 pm

The ability of biomoleculesand entire organismsto survive space has implications for a number of scientific questions: whether molecules from space could have seeded life on Earth, or whether life could spread among the inner planets following impacts. It also has practical implications, in that it dictates how careful we need to be in sterilizing hardware we send to other planets.

Chance gave some biologists access to a rocket, and they figured out a way to answer one of the questions. While prepping a sounding rocket for an experiment that briefly lofted some of their samples to space, they decided to put some DNA on the rocket's exterior. And when it returned to Earth 780 seconds later, they were able to recover the DNA and put it to use.

Sounding rockets are typically used for payloads that only have to be put into space briefly. In this case, the researchers were putting cells into the payload of a VSB-30, a two-stage, solid-fueled rocket manufactured in Brazil. While doing so, they decided it would be interesting to see what happened to samples outside of the protection of the payload. So they obtained some DNA called a plasmid that carried two genes: one that provides antibiotic resistance to bacteria, and a second that encodes a green fluorescent protein.

They placed some of the DNA on the underside of the payload container, in the grooves of some screws on the rocket's surface, and at specific locations on the nose of the vehicle. After all that was done, the VSB-30 was sent on a 13 minute trip from far-northern Sweden to space and back, after which the payload was recovered.

The researchers then simply washed the sites off with a sterile solution and check for the presence of DNA. Despite temperatures that were likely to have briefly reached 1,000 degrees Celsius on the exterior of the rocket, there was still DNA present. And, without any further cleaning up, that DNA could be inserted into bacteria and provide them with antibiotic resistance. When placed into cultured human cells, they glowed green. Sequencing the DNA revealed that it didn't contain more than a handful of mutations, which may or may not be a result of its time in space.

All of which suggests that DNA might be a tougher molecule than it's generally given credit fortough enough to survive re-entry on any hardware that we don't properly sterilize.

Duality in the human genome

Posted: at 11:43 pm

PUBLIC RELEASE DATE:

28-Nov-2014

Contact: Dr. Patricia Marquardt patricia.marquardt@molgen.mpg.de 49-308-413-1716 Max-Planck-Gesellschaft @maxplanckpress

This news release is available in German.

Humans don't like being alone, and their genes are no different. Together we are stronger, and the two versions of a gene - one from each parent - need each other. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have analysed the genetic makeup of several hundred people and decoded the genetic information on the two sets of chromosomes separately. In this relatively small group alone they found millions of different gene forms. The results also show that genetic mutations do not occur randomly in the two parental chromosome sets and that they are distributed in the same ratio in everyone.

In 2001 scientists announced the successful decoding of the first human genome. Since then, thousands more have been sequenced. The price of a genetic analysis will soon fall below the 1,000 dollar mark. Given this rapid pace of development, it's easy to forget that the technology used only reads a mixed product of genetic information. The analytical methods commonly employed do not take into account the fact that every person has two sets of genetic material. "So they are ignoring an essential property of the human genome. However, it's important to know, for example, how mutations are distributed between the two chromosome sets," says Margret Hoehe from the Max Planck Institute for Molecular Genetics, who carried out the study.

Hoehe and her team have developed molecular genetic and bioinformatic methods that make it possible to sequence the two sets of chromosomes in a human separately. The researchers decoded the maternal and paternal parts of the genome in 14 people and supplemented their analysis with the genetic material of 372 Europeans from the 1000 Genomes Project. "Fourteen people may not sound like a lot, but given the technical challenge, it is an unprecedented achievement," says Hoehe.

The results show that most genes can occur in many different forms within a population: On average, about 250 different forms of each gene exist. The researchers found around four million different gene forms just in the 400 or so genomes they analysed. This figure is certain to increase as more human genomes are examined. More than 85 percent of all genes have no predominant form which occurs in more than half of all individuals. This enormous diversity means that over half of all genes in an individual, around 9,000 of 17,500, occur uniquely in that one person - and are therefore individual in the truest sense of the word.

The gene, as we imagined it, exists only in exceptional cases. "We need to fundamentally rethink the view of genes that every schoolchild has learned since Gregor Mendel's time. Moreover, the conventional view of individual mutations is no longer adequate. Instead, we have to consider the two gene forms and their combination of variants," Hoehe explains. When analysing genomes, scientists should therefore examine each parental gene form separately, as well as the effects of both forms as a pair.

According to the researchers, mutations of genes are not randomly distributed between the parental chromosomes. They found that 60 percent of mutations affect the same chromosome set and 40 percent both sets. Scientists refer to these as cis and trans mutations, respectively. Evidently, an organism must have more cis mutations, where the second gene form remains intact. "It's amazing how precisely the 60:40 ratio is maintained. It occurs in the genome of every individual - almost like a magic formula," says Hoehe. The 60:40 distribution ratio appears to be essential for survival. "This formula may help us to understand how gene variability occurs and how it affects gene function."
