Correcting a SHAPE-directed RNA structure by a mutate-map-rescue approach [PDF]
, 2014 The three-dimensional conformations of non-coding RNAs underpin their biochemical functions but have largely eluded experimental characterization. Here, we report that integrating a classic mutation/rescue strategy with high-throughput chemical mapping enables rapid RNA structure inference with unusually strong validation. We revisit a paradigmatic 16S

Models of protein production along the cell cycle: an investigation of possible sources of noise [PDF]
PLOS ONE 15, no. 1 (January 16, 2020): e0226016, 2017 In this article, we quantitatively study, through stochastic models, the efects of several intracellular phenomena, such as cell volume growth, cell division, gene replication as well as fuctuations of available RNA polymerases and ribosomes. These phenomena are indeed rarely considered in classic models of protein production and no relative ...

Euglena gracilis chloroplast ribosomal RNA transcription units. II. Nucleotide sequence homology between the 16 S–23 S ribosomal RNA spacer and the 16 S ribosomal RNA leader regions. [PDF]
Journal of Biological Chemistry, 1980 The DNA sequences of two segments of the ribosomal RNA transcription units of Euglena gracilis Pringsheim strain Z chloroplast DNA have been determined. The first is from the 16 S to 23 S rRNA spacer region. The nucleotide sequence determined includes 64 bp from the 3'-end of the 16 S rRNA gene, the adjacent 87-bp spacer containing 68A-T base pairs, a ...

Allosteric collaboration between elongation factor G and the ribosomal L1 stalk directs tRNA movements during translation [PDF]
, 2009 Determining the mechanism by which transfer RNAs (tRNAs) rapidly and precisely transit through the ribosomal A, P and E sites during translation remains a major goal in the study of protein synthesis. Here, we report the real-time dynamics of the L1 stalk, a structural element of the large ribosomal subunit that is implicated in directing tRNA ...

Frequency of Bacetrial Content Finding in Persistant Periapical Lesions
Acta Stomatologica Croatica, 2017 Objectives: To determine the percentage of persistant apical lesions positive for bacterial nucleic acids, to detect microorganisms difficult to cultivate in persistant apical lesions by PCR and relate them to endodontic failure, clinical symptoms and ...

The complete mitochondrial genome of Anas penelope (Anatidae: Anas)
Mitochondrial DNA. Part B. Resources, 2020 The complete mitochondrial DNA genome of the Eurasian Wigeon, Anas penelope, was mapped by the next-generation sequencing and Mega 7.0. The circular mitogenome (16,596 bp in length) contains 13 protein-coding genes, 2 rRNA genes (12S ribosomal RNA and ...

Association between semen microbiome disorder and sperm DNA damage
Microbiology SpectrumDNA fragmentation index (DFI), a new biomarker to diagnose male infertility, is closely associated with poor reproductive outcomes. Previous research reported that seminal microbiome correlated with sperm DNA integrity, suggesting that the microbiome may

The complete mitochondrial genome of Glossaulax reiniana (Littorinimorpha: Naticidae)
Mitochondrial DNA. Part B. Resources, 2018 In the present study, the complete mitochondrial genome of Glossaulax reiniana was determined using the next-generation sequencing. The circular genome was found to be 15,254 bp in length and had an overall nucleotide composition of 30.6% A, 14.1% C, 15 ...
