New method improves single-cell genomics analyses Single-cell RNA-sequencing is a relatively new technology that helps scientists understand how genes are expressed in different types of healthy tissue and in cancers.
With single-cell genomics we take cells from a tissue and group them into different types based on their expression profile identifying subtypes that may have a range of functional roles.
Our model now makes it possible to create such profiles using single-cell genomics s
"Most remarkably, we found the genetic changes that likely underlie the evolution of pregnancy are linked to domesticated transposable elements that invaded the genome in early mammals.
The team found that this process was driven by ancient transposons--stretches of non-protein coding DNA that can change their position within the genome.
By randomly inserting themselves into other places in the genome, transposons appear to have passed on this activation mechanism to nearby genes."

Larger scale gene function studies A relatively new method of targeting specific DNA sequences in zebrafish could dramatically accelerate the discovery of gene function and the identification of disease genes in humans, according to scientists at the National Human genome Research
. a senior investigator with NHGRI Translational and Functional genomics Branch and head of the Developmental Genomics Section. hat we have done is to establish an entire pipeline for knocking out many genes and testing their function quickly in a vertebrate

#Scientists construct first whole genome sequence of bighorn sheep Geneticists at the University of Alberta have constructed the first whole genome sequence of a bighorn sheep in a new study that could have a significant impact on conservation efforts of the species,
To construct a whole genome sequence, the DNA is first run through a sequencer to identify small strings of building blocks, called nucleotides.
The strings of nucleotides are joined then together to produce a complete picture. he process of ordering the nucleotides into a genome is much like assembling a jigsaw puzzle,
which uses an existing genome sequence as a reference point to streamline the process. ere, one starts with the same jigsaw pieces,
and for genome sequencing this usually results in a much more complete picture being put together in less time than de novo assembly.
In this case, the reference used for alignment was the already complete whole genome sequence of a domestic sheep.
Full genome sequences are still relatively rare; for context, only 108 mammals are listed in the National Center for Biotechnology Information database. ntil recently,
generating a genome sequence of any organism was nearly impossible, notes Miller. The majority of organisms sequenced so far have been domestic laboratory species such as fruit flies or lab mice.
and cost-effective enough to be useful in obtaining whole genome sequences of wildlife species, like bighorn sheep.
This opens new avenues of research such as using genomics to plan conservation and management actions for at-risk species. Constructing a whole genome sequence of the bighorn sheep will also help by providing a reference for new studies,
