English synonyms.

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface. The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell. The plasma membrane, or the cell membrane, provides protection for a cell.

Genetic recombination also known as genetic reshuffling is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes , genetic recombination during meiosis can lead to a novel set of genetic information that can be further passed on from parents to offspring. During meiosis in eukaryotes , genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes. The information transfer may occur without physical exchange a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed see SDSA — Synthesis Dependent Strand Annealing pathway in Figure ; or by the breaking and rejoining of DNA strands, which forms new molecules of DNA see DHJ pathway in Figure. Recombination may also occur during mitosis in eukaryotes where it ordinarily involves the two sister chromosomes formed after chromosomal replication. In this case, new combinations of alleles are not produced since the sister chromosomes are usually identical. In meiosis and mitosis, recombination occurs between similar molecules of DNA homologous sequences. In meiosis, non-sister homologous chromosomes pair with each other so that recombination characteristically occurs between non-sister homologues. In both meiotic and mitotic cells, recombination between homologous chromosomes is a common mechanism used in DNA repair. Gene conversion — the process during which homologous sequences are made identical also falls under genetic recombination.

In other projects. Numerous RNA viruses are capable of genetic recombination when at least two viral genomes are present in the same host cell.

Recent advances in single-cell genomics provide an alternative to gene-centric metagenomics studies, enabling whole genome sequencing of uncultivated bacteria. However, single-cell assembly projects are challenging due to i the highly non-uniform read coverage, and ii a greatly elevated number of chimeric reads and read pairs. While recently developed single-cell assemblers have addressed the former challenge, methods for assembling highly chimeric reads remain poorly explored. We present algorithms for identifying chimeric edges and resolving complex bulges in de Bruijn graphs, which significantly improve single-cell assemblies. We demonstrate that SPAdes enables sequencing mini-metagenomes and benchmark it against various assemblers. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Background: Adaptation to drought-prone environments requires robust root architecture. Genotypes with a more vigorous root system have the potential to better adapt to soils with limited moisture content. However, root architecture is complex at both, phenotypic and genetic level. Customized mapping panels in combination with efficient screenings methods can resolve the underlying genetic factors of root traits. Results: A mapping panel of spring barley genotypes was evaluated for root and shoot architecture traits under non-stress and osmotic stress. A genome-wide association study elucidated 65 involved genomic regions. Among them were 34 root-specific loci, eleven hotspots with associations to up to eight traits and twelve stress-specific loci. A list of candidate genes was established based on educated guess. Selected genes were tested for associated polymorphisms. By this, 14 genes were identified as promising candidates, ten remained suggestive and 15 were rejected.

New York: Garland Science. Mandarin Chinese images. DNA damages caused by a variety of exogenous agents e. During meiosis in eukaryotes , genetic recombination involves the pairing of homologous chromosomes. Thus, explanations for the adaptive function of meiosis that focus exclusively on crossing-over are inadequate to explain the majority of recombination events. Archived from the original on Heterochiasmy occurs when recombination rates differ between the sexes of a species. Collocations are words that are often used together and are brilliant at providing natural sounding language for your speech and writing. Traditional Chinese images. Recombination can occur infrequently between animal viruses of the same species but of divergent lineages. This may be followed by information transfer between the chromosomes. Journal of Molecular Evolution. Indicated on the right side is a "crossover" CO type, where the flanking regions of the chromosomes are exchanged, and on the left side, a "non-crossover" NCO type where the flanking regions are not exchanged. Journal of Bacteriology. Recombination can occur between DNA sequences that contain no sequence homology.

Metrics details. Plant diseases caused by pathogenic fungi are devastating. However, commonly used fungicides are harmful to the environment, and some are becoming ineffective due to fungal resistance.

Main article: Chromosomal crossover. Mastering politeness in English: Harness the charm of 'please' and 'thank you' for positive and impactful communication. December The NCO recombinants illustrated on the left in the figure are produced by a process referred to as "synthesis dependent strand annealing" SDSA. Read about the team of authors behind Collins Dictionaries. This article incorporates public domain material from Science Primer. This pathway is labeled in the figure as the DHJ double-Holliday junction pathway. Geneticists can also use this method to infer the presence of certain genes. In meiosis and mitosis, recombination occurs between similar molecules of DNA homologous sequences. French images. Two types of recombinant product are produced. Portal : Biology.
