Now, researchers from the Okinawa Institute of Science and Technology (OIST), in collaboration with a number of other research institutes including K MIKIMOTO & CO, LTＤ, Pearl Research Institute and Japan Fisheries Research and Education Agency, have constructed a high-quality, chromosome-scale genome of pearl oysters, which they hope can be used to find resilient strains.

Traditionally, when a genome is sequenced, the researchers merge the pair of chromosomes together. (thefishsite.com)
OIST researchers Mr Manabu Fujie and Ms Mayumi Kawamitsu used state-of-the-art technology to sequence the genome. (thefishsite.com)
The researchers sequenced the two different pumpkin species to better understand their contrasting desirable traits: C. moschata is known for its resistance to disease and other stresses, such as extreme temperatures, while C. maxima is better known for its fruit quality and nutrition. (cornell.edu)
The researchers also found that the chromosome has a large number of sequences repeated throughout the genome. (innovations-report.com)
A Better Way to Find RNA Virus Needles in the Proverbial Database Haystacks Researchers combed through more than 5,000 data sets of RNA sequences generated from diverse environmental samples around the world, resulting in a five-fold increase of RNA virus diversity. (doe.gov)
It is this unique sequence that researchers use to identify and quantify the protein. (lu.se)
By using three consecutive mass analysis units in mass spectrometry, the researchers can now filter out rare protein sequences. (lu.se)

Sex chromosomes are typically thought to evolve as recombination is halted between a homologous pair of chromosomes in one sex. (nature.com)
Amino-acid sequence and structure comparison suggested that the enzyme belongs to a group of enzymes classified as archaeal Holliday junction-resolving enzymes, which are typically divalent metal ion-binding dimers that are able to cleave X-shaped dsDNA-Holliday junctions (Hjs). (iucr.org)
Each person typically has 23 pairs of chromosomes. (cdc.gov)

These chromosomes are tightly coiled and packed strings of a remarkable molecule called DNA (Deoxyribonucleic Acid). (probe.org)

This spacer and the putative promoter 600 bp upstream from the hsa‐miR‐200c stem-loop contain six putative binding sequences for [zinc‐finger E‐box binding homeobox 1] ZEB1, two of which were restricted to ZEB factors (Z‐box 1 and 2, CAGGTA). (wikiversity.org)

The other authors of this study, Dr Yoshihiko Suzuki, former postdoctoral scholar in OIST's Algorithms for Ecological and Evolutionary Genomics and now at the University of Tokyo and Dr Takeuchi reconstructed all 28 chromosomes and found key differences between the two chromosomes of one pair-chromosome pair 9. (thefishsite.com)
The genome has many insertion sequences and many G-C base pair differences, which means frequent recombination. (kenyon.edu)

In higher eukaryotes, this cis-regulatory information is organized into modular units [cis-regulatory modules (CRMs)] of a few hundred base pairs. (sdbonline.org)
However, the cis-regulatory sequence controlling this posterior expression pattern has not been precisely identified. (sdbonline.org)
This was something that had not been seen before, which shows the advantage of editing a gene's regulatory sequence at its normal location within the genome. (elifesciences.org)
used the CopyCat tool to delete the regulatory sequence and replace it with sequences from three other species of flies. (elifesciences.org)

LINES (long interspersed elements) ~6000 to 7000 base pairs. (powershow.com)
The advent of long-read sequencing technologies and associated algorithms have now made it possible to systematically assemble these regions from native DNA for the first time. (pacb.com)
The issues arose when they tried to stitch together two very long chromosome pieces, which would attach imperfectly. (zmescience.com)
It was long believed that there were 48 chromosomes in total, but no one was sure because it was difficult to obtain good microscope slides. (lu.se)

Although we have a detailed understanding of the evolutionary consequences of the loss of recombination for sex chromosome evolution 1 , 2 , we still do not understand the evolutionary forces acting to halt recombination in the first place. (nature.com)

Since pearl oysters have 14 pairs of chromosomes, they have 28 in total. (thefishsite.com)
This graph shows the total number of publications written about "Chromosomes, Artificial, Yeast" by people in Harvard Catalyst Profiles by year, and whether "Chromosomes, Artificial, Yeast" was a major or minor topic of these publication. (harvard.edu)
Their answer was to use shorter chromosome sequences and reduce the total number of chromosomes to 19 pairs, one fewer than mice have naturally. (zmescience.com)
a total of 839 ospC sequences were analyzed. (cdc.gov)

Having the genome sequenced also means that they are able to determine other species that are related to yersinia pestis which can prevent future outbreaks. (kenyon.edu)
Yersinia pestis has three sub species in which only two have been sequenced, strain KIM and strain CO92. (kenyon.edu)
This research is a breakthrough in bioengineering technology, helping to understand the impact of large-scale remodelling of mammalian chromosomes, and to gain a deeper understanding of the molecular mechanisms behind growth and development, reproductive evolution, and even the creation of a species. (zmescience.com)

Most of the unread genome just belonged to centromeric regions, these are special sections of chromosomes that are necessary for cell division, and they usually consist of tandem repeating DNA sequence units. (vechnayamolodost.ru)

When a microbe recognizes that it has been invaded, it incorporates a small piece of the invader's DNA into one of its CRISPR units as a new spacer sequence. (lbl.gov)
They used CRISPR to manipulate the chromosomes contained by a unique reproductive stem cell - the mouse which they created specifically for this experiment. (zmescience.com)
Here especially highlighted variations of FISH are molecular combing, chromosome orientation-FISH (CO-FISH), telomere-FISH, parental origin determination FISH (POD-FISH), FISH to resolve the nuclear architecture, multicolor-FISH (mFISH) approaches, among other applied in chromoanagenesis studies, Comet-FISH, and CRISPR-mediated FISH-applications. (frontiersin.org)

The dominant model of sex chromosome evolution posits that recombination is suppressed between emerging X and Y chromosomes in order to resolve sexual conflict. (nature.com)

The sex chromosomes of the guppy ( Poecilia reticulata ) have been of interest for more than a century, following early reports that many sexually selected colour traits are passed through the patriline on the Y chromosome 8 , 9 . (nature.com)

Biological men are XY, so sperm can either carry an X or Y chromosome. (familyeducation.com)
During fertilization the egg and sperm join together, forming a cell with a full complement of chromosomes that now forms the genetic blueprint for the new individual. (familyeducation.com)
