PCR primers for metazoan nuclear 18S and 28S ribosomal DNA sequences. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Metagenetic analyses, which amplify and sequence target marker DNA regions from environmental samples, are increasingly employed to assess the biodiversity of communities of small organisms. Using this approach, our understanding of microbial

A noninvasive molecular approach: exploiting species-locus-specific PCR primers in defeating numts and DNA cross-contamination of cercopithecidae [PDF]

open access: yes, 2017
The lack of a standardized, noninvasive molecular approach to studying genetic aspects of primates has made it hard for primatologists to decode the evolutionary history of these species.

Standard and Light-Cycler PCR methods for animal DNA species detection in animal feedstuffs [PDF]

open access: yes, 2008
In this work four species-specific primers and probes were designed and evaluated for the detection and quantification of bovine, ovine, swine and chicken mitochondrial DNA in feeds.

STUDI PERBANDINGAN PEMAKAIAN PRIMER HBS1 DAN HBS2 DENGAN PRIMER P7 DAN P8 DALAM DETEKSI DNA VIRUS HEPATITIS B PADA PENDONOR DARAH

open access: yesFlorea: Jurnal Biologi dan Pembelajarannya, 2020
Examination of the hepatitis B virus as a disease of hepatitis serologically has been carried out a lot, but this serological examination can experience problems if there is a low window period, so even though a negative test result is still possible in ...

Nanoparticle labels for pathogen detection through nucleic acid amplification tests [PDF]

open access: yes, 2014
YesMagnetic nanoparticles and surface-enhanced Raman scattering (SERS) active nanoparticles were coated with short chain DNA tags. These were then used to identify a target bacterial DNA sequence.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Arabidopsis RecQl4A suppresses homologous recombination and modulates DNA damage responses [PDF]

open access: yes, 2005
The DNA damage response and DNA recombination are two interrelated mechanisms involved in maintaining the integrity of the genome, but in plants they are poorly understood.

Comparison of different primes for PCR-based diagnosis of cutaneous leishmaniasis

open access: yesBrazilian Journal of Infectious Diseases
OBJECTIVE: The objective of this study was to analyze different primers that are commonly used in epidemiological studies for the detection of Leishmania DNA by PCR, and to compare them to the conventional direct parasite search for American cutaneous ...

Species-specific Real Time-PCR primers/probe systems to identify fish parasites of the genera Anisakis, Pseudoterranova and Hysterothylacium (Nematoda: Ascaridoidea) [PDF]

open access: yes, 2018
Ascaridoid nematodes belonging to the genera Anisakis and Pseudoterranova are heteroxenous parasites, involving marine mammals as definitive hosts in their life-cycles, whereas crustaceans (krill), fish and squids acting as intermediate/paratenic hosts.

Primer removal during mammalian mitochondrial DNA replication

open access: yesDNA Repair, 2015
The small circular mitochondrial genome in mammalian cells is replicated by a dedicated replisome, defects in which can cause mitochondrial disease in humans. A fundamental step in mitochondrial DNA (mtDNA) replication and maintenance is the removal of the RNA primers needed for replication initiation. The nucleases RNase H1, FEN1, DNA2, and MGME1 have
