They live inside their host's cells and have highly specialized features: They are only able to reproduce inside the host's cells, they have the smallest
known genome of all organisms with a cell nucleus (eukaryotes) and they posses no mitochondria of their own (the cell's power plant).
«With the ability to study the
entire genome of an organism, biologists are confronted with the task of managing enormous amounts of data,» said Kevin Strange, Ph.D., MDI Biological Laboratory president.
To study this I focus on sequencing and
analyzing genomes of organisms, especially microbes and using phylogenomic analysis (see my lab site here which has more information on lab activities).
The scientists combined phylogenetics — the study of evolutionary relationships between different species, with genomics — the study of how
the genome of an organism conditions its biology.
The molecular clock approach is based on the principle that mutations accumulate in
the genomes of all organisms over the course of time.
Essentially, she sequences
the genomes of every organism in a given water or soil sample en masse; an entire community at once.
Evolution takes eons, but it leaves marks on
the genomes of organisms that can be detected with DNA sequencing and analysis.
You have said that scientists should record
the genomes of all organisms on Earth because you believe many species are headed for extinction.
With the aid of advanced gene sequencing, comparative DNA analysis, and endless cross-referencing of
the genomes of organisms from the three — or perhaps four — domains of life, a fuller concept of viruses and their role in evolution has begun to coalesce.
«It emphasizes just how much novelty we can find by sequencing
the genomes of organisms that can't be grown in the lab,» Koonin said.
A multi-institutional team has sequenced the genome of the mosquito that transmits the Zika virus uisng a new way to sequence
the genome of an organism entirely from scratch, dramatically cheaper and faster.
A team spanning Baylor College of Medicine, Rice University, Texas Children's Hospital and the Broad Institute of MIT and Harvard has developed a new way to sequence genomes, which can assemble
the genome of an organism, entirely from scratch, dramatically cheaper and faster.
«The team shows it is possible to introduce in a rational way large - scale changes in
the genome of an organism.
The basis for this observation is that
the genomes of all organisms are written in an «alphabet» that consists of only four nucleobase molecules: adenine (A), thymine (T), guanine (G) and cytosine (C).
Just as paleontologists use fossil bones to date when a species originated, paleovirologists can use remnants of viral genes scattered around
the genomes of the organisms they infect.
This is, in part, due to the difficulty of engineering
the genomes of organisms.
«It is now routine to generate virtually any change in
the genome of an organism of choice at will,» he notes.
Now, three decades after those weapons were destroyed, scientists have sequenced
the genome of the organism — a pathogen typically found in pigs called Brucella suis.
Building off this work, TIGR scientists are leveraging the information from
the genome of this organism to study the ecology of microbes living in diverse hot springs, such as those in Yellowstone National Park.
Researchers with the Human Genome Project and various commercial ventures are racing to sequence
the genomes of organisms in an effort to catalog all their genes.
Today, in the post-genomic era, we need to study and understand biological phenomena and systems in their full complexity, in terms of the sequence and functions of
the genomes of organisms.
Objective: To understand the first steps in the evolution of photosynthetic eukaryotes and the impact plastidial endosymbioses (involving cyanobacteria or unicellular algae) had on
the genomes of these organisms that are critical to the functioning of ecosystems.
Curious, the researchers sequenced
the genome of the organism.
