Plasmid

Description Plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains. Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate independently of the bacterial chromosome. They are not essential to the bacterium but may confer a selective advantage. One class of plasmids, colicinogenic (or Col) factors, determines the production of proteins called … Read more

Polymerase Chain Reaction (PCR)

Introduction  PCR (polymerase chain reaction) is a revolutionary method developed by Kary Mullis in the 1980s. Gentaur PCR is based on the use of DNA polymerase’s ability to synthesize a new DNA strand complementary to the offered template strand. Because DNA polymerase can add a nucleotide only to a preexisting 3′-OH group, it needs a … Read more

Mitosis

Introduction Mitosis is a process of cell duplication or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry genetic information. Following is a brief treatment of mitosis. For full treatment, see Growth: … Read more

Chromosome-level genome assembly of the common chaffinch (Aves: Fringilla Coelebs): a valuable resource for evolutionary biology

Chromosome-level genome assembly of the common chaffinch (Aves: Fringilla Coelebs): a valuable resource for evolutionary biology

The common chaffinch, Fringilla coelebs, is one of the most common, widespread and well-studied passerines in Europe, with a broad distribution encompassing Western Europe and elements of Asia, North Africa and the Macaronesian archipelagos. We current a high-quality genome assembly of the common chaffinch generated utilizing Illumina shotgun sequencing together with Chicago and Hi-C libraries. … Read more

Convergent Adaptation to Quantitative Host Resistance in a Major Plant Pathogen

Convergent Adaptation to Quantitative Host Resistance in a Major Plant Pathogen

Plant pathogens can adapt to quantitative resistance, eroding its effectiveness. The purpose of this work was to reveal the genomic foundation of adaptation to such a resistance in populations of the fungus Pseudocercospora fijiensis, a main devastating pathogen of banana, by finding out convergent adaptation on totally different cultivars. Samples from P. fijiensis populations displaying a native adaptation sample … Read more

From e-voucher to genomic data: Preserving archive specimens as demonstrated with medically important mosquitoes (Diptera: Culicidae) and kissing bugs (Hemiptera: Reduviidae)

From e-voucher to genomic data: Preserving archive specimens as demonstrated with medically important mosquitoes (Diptera: Culicidae) and kissing bugs (Hemiptera: Reduviidae)

Scientific collections such as the U.S. National Museum (USNM) are crucial to filling data gaps in molecular systematics research. The world taxonomic obstacle has resulted in a discount of professional taxonomists producing new collections of uncommon or understudied taxa and these massive historic collections stands out as the solely dependable supply of fabric for some … Read more

Construction of a chromosome-level genome and variation map for the Pacific oyster Crassostrea gigas

Construction of a chromosome-level genome and variation map for the Pacific oyster Crassostrea gigas

The Pacific oyster (Crassostrea gigas) is a extensively distributed marine bivalve of nice ecological and financial significance. In this examine, we offer a high-quality chromosome-level genome assembled utilizing Pacific Bioscience lengthy reads and Hi-C-based and linkage-map-based scaffolding applied sciences and a high-resolution variation map constructed utilizing large-scale resequencing evaluation. The 586.8-Mb genome consists of 10 … Read more

Genome-wide enhancer annotations differ significantly in genomic distribution, evolution, and function.

Non-coding gene regulatory enhancers are important to transcription in mammalian cells. As a end result, a big number of experimental and computational methods have been developed to determine cis-regulatory enhancer sequences. Given the variations in the organic indicators assayed, some variation in the enhancers recognized by totally different strategies is predicted; nevertheless, the concordance of … Read more
