Sentence examples for empty chromosomes from inspiring English sources

Many of these regions were found on the empty chromosomes that lack any annotated functional element.

These observations raise basic questions about how and why such empty chromosomes are faithfully maintained, replicated and transmitted.

Thus, there is a weak trend supporting the prediction that having highly expressed regions is a predictor of conservation for these empty chromosomes.

We previously showed that, of the 23 empty chromosomes in the mitochondrial genome of the population used in this study (BRP), 15 were shared with a second population of S. noctiflora (OSR), whereas eight were unique to BRP.

However, we also found that many of the seemingly empty chromosomes are shared across populations, raising the possibility that they are conserved by natural selection and contain some type of unidentified functional elements.

Here, we use RNA-seq to examine patterns of transcript abundance and RNA editing in the 7-Mb mitochondrial genome of S. noctiflora in order to identify candidate functional elements that could potentially explain the maintenance of enormous quantities of non-coding content and the existence of seemingly empty chromosomes in this genome.

We have performed a genome-wide analysis of mitochondrial transcription in Silene noctiflora to assess the possibility that there are uncharacterized functional elements that could explain the maintenance of the massive quantities of intergenic DNA and empty mitochondrial chromosomes in this species.

Strains carrying the cortical pHluorin were constructed by amplifying plasmid pADH1pr-PSR1-RMP with primers (URA3-tTA-intChr1F and R) that allowed insertion into a second empty region of chromosome 1 (17068–17161).

Strains expressing PMA1 or PMA1-mCherry from a GAL promoter were constructed by transformation of GEV yeast strains with NotI-digested pAG306-GAL-PMA1 chr1 or pAG306-GAL-PMA1-mCherry pAG306-GAL-PMA1-mCherry pAG306-GAL-PMA1-mCherry pAG306-GAL-PMA1-mCherry6–199457) (Hughes and Gottschr1ng, 2012).

They will try to implant artificial chromosomes into empty bacterial cells, in the hope that they will come alive.

They want to synthesise the entire DNA sequence of an individual bacterium, with crucial modifications to make the organism do new and interesting things and to pop the new chromosome into an empty cell.
