The aim of this study was to investigate the duplication events within the SABATH gene family in cassava using computational tools. By analyzing the similarities between coding DNA sequences, we identified potential duplicated gene pairs and examined their structures. In addition, we assessed the expression profiles of SABATH genes across various cassava tissues during key growth and developmental stages.

Hypertrophic cardiomyopathy (HCM) is a common genetic cardiovascular disease and a major cause of sudden death. It is also involved in increasing morbidity and mortality of various cardiovascular diseases. Genetic factors have been found to be important in determining the phenotypic manifestation of cardiac hypertrophy. However, only 50–60% of HCM patients have been identified as having pathogenic variants in known genes, suggesting that more studies are needed to find more disease genes.

Concept of hybrid molecules: When double strand DNA is steamed to a temperature exceed the melting temperature (Tm), it will separate into 2 single strands DNA due to breaks of H bonds. If the reaction temperature is then decreased slowly plus other appropriate experimental conditions, these ssDNA will pair again. This phenomenon is called the hybridization of molecules. Characteristic of the hybrid molecules: Specificity, the re-pairing occurs only between two complementary sequences.

In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences.[1] Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix. Gaps are inserted between the residues so that identical or similar characters are aligned in successive columns.

We report here the direct evidence for the formation of alternative DNA structures in a plasmid DNA, termed pTIR10, containing a 0.23-kb pyrimidine/purine-biased (Pyr/Pur) stretch isolated from the rat genome. Long Pyr/Pur sequences are abundant in eukaryotic genomes, and they may modulate the biological activity of genes and genomes via formation of various types of triplex-related structures. The plasmid DNA in sodium acetate buffer (pH 4.35) was deposited on APS-modified mica, and after drying it was imaged with an atomic force microscope in air. ...

Recently, we have identified and purified minisatellite DNA binding proteins (MNBPs) that bind to the mouse hypervariable minisatellite Pc-1, from NIH3T3 cells. This study describes the isolation and characterization of a mouse leucine-rich protein (mLRP130) as one of the MNBPs that binds to the C-rich strand of Pc-1. The mLRP130 cDNA was demonstrated to encode a polypeptide of 1306 aminoacid residues with a deduced molecular mass of 137 kDa, and the mLRP130 mRNA is detected in various organs, including heart, brain, liver, skeletal muscle, kidneys and testes.

DNA transactions in eukaryotes require that proteins gain access to target sequences packaged in chromatin. Further, interactions between distinct nucleoprotein complexes are often required to generate higher-order structures. Here, we employed two prokaryotic site-specific recombination systems to investigate how chromatin packaging affects the assembly of nucleoprotein structures of different complexities at more than 30 genomic loci. The dynamic nature of chromatin permitted protein–DNA and DNA–DNA interactions for sites of at least 34 bp in length.

During the development of multicellular organisms, both transient and stable gene expression patterns have to be established in a precisely orchestrated sequence. Evidence from diverse model organisms indicates that this epigenetic program involves not only transcription factors, but also the local structure, composition, and modification of chromatin, which define and maintain the accessibility and transcriptional competence of the nucleosomal DNA template.

Primary structural information including the complete nucleotide sequence of the ®rst insect aldehyde oxidase (AO) was obtained from the common house mosquitoCulex quinquefasciatus(Say) through cloning and sequencing of both genomic DNA and cDNA. The deduced amino-acid sequence encodes a 150-kDa protein of 1266 amino-acid residues, which is consistent with the expected monomeric subunit size of AO.

Heat shock transcription factors (HSFs) are characterized by their ability, upon activation, to bind to heat shock response elements (HSE) present in the promoter of their target genes. HSE are composed of inverted repeats of the pentamer nGAAm. In this study, we compare the embryonic HSF2 protein, purified from F9 embryonal carcinoma cells tumor, and thein vitro synthesized HSF2. We show that the context of HSF2 synthesis influences its thermosensitivity and DNA-binding properties.

The RuvA, RuvB andRuvCproteins ofEscherichia coliact together to process Holliday junctions formed during recombination and DNA repair. RuvA has a well-de®ned DNA binding surface that is sculptured speci®cally to accommodate a Holliday junction and allow subsequent loading of RuvB and RuvC. A negatively charged pin pro-jecting from the centre limits binding of linear duplexDNA. The amino-acid sequences forming the pin are highly con-served.

Special oligonucleotides for targeted gene correction have attracted increasing attention recently, one of which is the chimericRNAÆDNAoligonucleotide (RDO) system. RDOs for targeted gene correction were first designed in 1996, and are typically 68 nucleotides in length including continuous RNA andDNA sequences (RNA is 2¢-O-methyl-modified).
