when performing metagenomic analysisequencing scrambled genetic material from many organisms at once. The Berkeley team began the reassembly process with algorithms that assembled bits of the sequenced genetic code into slightly longer strings called contigs. ou no longer have tiny pieces of DNA,
Brown said. hen you figure out which of these larger pieces are part of a single genome.
This part of the process, in which contigs are combined to reconstruct the genome sequence is called genome binning.
To execute it, the researchers relied on another set of algorithms, customized for the task by Itai Sharon,
They also assembled some of the genomes manually, making decisions about what goes where based on the fact that some characteristics are consistent for a given genome.
For example, the percentage of Gs and Cs will be similar on any part of an organism DNA.
the researchers had eight full bacterial genomes and 789 draft genomes that were roughly 90 percent complete.
Some of the organisms had been glimpsed before; many others were completely new. The reason no one had found these organisms before is that the traditional method used to search for small forms of life doesn work for everything.
By reconstructing complete or nearly complete genomes, Brown and his collaborators were able to locate 16s rrna genes
All the organisms they found have very short genomes about one million base pairs (compare that to E coli,

#New system for human genome editing has potential to increase power and precision of DNA engineering A team including the scientist who first harnessed the CRISPR-Cas9 system for mammalian genome editing has identified now a different CRISPR system with the potential for even simpler and more precise genome engineering.

The Cpf1 system represents a new generation of genome editing technology. CRISPR sequences were described first in 1987
The application of the CRISPR-Cas9 system for mammalian genome editing was reported first in 2013, by Zhang and separately by George Church at Harvard university.
This could be an advantage in targeting some genomes, such as in the malaria parasite as well as in humans. he unexpected properties of Cpf1 and more precise editing open the door to all sorts of applications,

These experiments show exceptional specificity, demonstrating that the technology is capable of targeting single sequences of the genome.
The power to control the genome switches would be especially important for studying and potentially treating human diseases such as cancer,

Retrieving small genomes from a mix of organisms Scientists from the IZW led by Alex Greenwood publish in PLOS ONE a simple way to retrieve small genomes from a mix of various organisms.
how to retrieve the genome of a specific pathogen from a mixture of DNAS in a patient and its microbial cohabitants?
Analysis of the sequences and comparison with reference data demonstrated that the complete mitochondrial genome of the rodents had been retrieved from the DNA pool.
In fact entire mitochondrial genomes and almost the entire genome sequence of a bacterium were obtained when specifically tested for the efficiency of the bycatch principle.
Capflank opens doors to completely new possibilities e g. in the genetic analysis of pathogens. We can use short preserved gene sequences to yield the genome
(or at least large sections of it) from pathogenic variants of influenza viruses for example or from completely new pathogens explains Greenwood.
From the intestinal bacterium Escherichia coli contained in a human urine sample the scientists retrieved 90 per cent of the genome in one go.

They are only able to reproduce inside the host's cells they have known the smallest genome of all organisms with a cell nucleus (eukaryotes) and they posses no mitochondria of their own (the cell's power plant.
Due to their phenomenal high molecular evolution rate genome analysis has so far been rather unsuccessful:
The analysis of the entire genome had several surprises in store for them: The genome resembles more that of a fungi than a microsporidium
and in addition also has a mitochondrial genome. The new species now named Mitosporidium daphniae thus represents the missing link between fungi and microsporidia.
With the help of scientists in Sweden and the U s. the Basel researchers rewrote the evolutionary history of microsporidia.
but that its genome is rather atypical for a microsporidium. It resembles much more the genome of their fungal ancestors.
Genome modificationsthe scientists thus conclude that the microsporidia adopted intracellular parasitism first and only later changed their genome significantly.
These genetic adaptations include the loss of mitochondria as well as extreme metabolic and genomic simplification. Our results are not only a milestone for the research on microsporidia
CRISPR is a technique that emerged a few years ago as a way to edit DNA anywhere within the genome.
The selected RNA serves as an adaptor that determines the target anywhere within the genome.
The Weissman team led experiments demonstrating that CRISPR molecules incorporating the Suntag can be used to precisely control gene expression of many genes within the genome.
The adaptation of the Suntag for CRISPR activation makes it possible to systematically probe the biological roles of all genes within the genome in a single experiment.
We can now sequence the entire genome of a cancer cell and what we're finding is that many cancers have mutations in the epigenetic machinery.

#Non-coding half of human genome unlocked with novel sequencing technique An obscure swatch of human DNA once thought to be nothing more than biological trash may actually offer a treasure trove of insight into complex genetic-related diseases such as cancer
This mysterious tightly packed section of the vast non-coding section of the human genome widely dismissed by geneticists as junk previously was thought by scientists to have no discernable function at all.
and that mutations which could affect other parts of the genome are capable of occurring.
This work opens up the other non-coding half of the genome. Maggert explains that chromosomes are located in the nuclei of all human cells
This enables us to answer a very specific question right here in the lab. The uncharted genome sequences have been a point of contention in scientific circles for more than a decade according to Maggert a Texas A&m faculty member since 2004.
It had long been believed that the human genome--the blueprint for humanity individually and as a whole--would be packed with complex genes with the potential to answer some of the most pressing questions in medical biology.
When human DNA was sequenced finally with the completion of the Human genome Project in 2003 he says that perception changed.
Based on those initial reports researchers determined that only two percent of the genome (about 21000 genes) represented coding DNA.
Now thanks to Aldrich's and Maggert's investigation of heterochromatin the groundwork has been laid to study the rest of the genome.

#Genome Editing to Reverse Bubble Boy Syndrome Researchers used an emerging technique to correct the gene behind a fatal immune system disorder in an infant.
The latest report shows how scientists can correct a broken gene as it sits in the patient genome.
Genome editing technology is considered a promising new tool for curing disease. For decades gene therapy has meant that a virus delivers a functional copy of a gene that is dysfunctional in a patient.
and the therapeutic version typically remains separate from the rest of the genome. The technology has drawbacks.
First, by sitting outside of the genome, the activity of therapeutic gene isn regulated properly.
In some cases, the therapeutic copy is delivered by a retrovirus the plunks the new gene down near randomly in the patients genome,
