Abstract:
Molecular approaches that target the total DNA pool recovered from permanently anoxic marine ecosystems have revealed an extraordinary diversity of prokaryotes and unicellular eukaryotes. However, the presence of gene sequences contained within the extracellular DNA pool is still largely neglected. We have investigated the preservation, origin and genetic imprint of extracellular DNA recovered from permanently anoxic deep-sea sediments of the Black Sea. Despite high DNase activities, huge amounts of total extracellular DNA were found in both the surface and sub-surface sediment layers, suggest

Abstract:
Abstract The human VHVI gene segment, the sole member of the VHVI gene family, is remarkable in that it is the most D-proximal VH gene segment and is apparently nonpolymorphic. Here we report that the VHVI gene segment has been remarkably preserved in primate evolution. We were unable to detect RFLP among several primates, and nucleotide sequences of several VHVI gene segments showed remarkable conservation. No differences were detected in the nucleotide sequences of the VHVI gene segment from three unrelated chimpanzees. These findings suggest that the VHVI gene segment has been strongly sele

Abstract:
SUMMARY The nucleotide sequences of cloned Escherichia coli heat-stable toxin 1 (STI) genes isolated from bovine, avian, and porcine origins were determined. They were found to be almost identical to that of Tn1681. The nucleotide sequences were completely preserved in bovine and avian genes, whereas the porcine gene had different sequences at 3 positions in the external region of STI structural genes, as compared with Tn1681. The amino acid sequences of the STI genes of the 3 animal origins corresponded to STIa, which had initially been found in a bovine strain.

Abstract:
Bacteria from genus Bradyrhizobium can establish symbiosis with soybean and supply the plant nitrogen demands via biological nitrogen fixation (BNF). This study aimed to characterize genes related to BNF efficiency in B. japonicum strains contrasting in BNF efficiency. These gene sequences were previously identified in B. japonicum (strain S370) as probably related to the BNF efficiency in soybean using a DNA subtractive technique. These genes were amplified with primers based on B. japonicum USDA110 genome. The PCR products were digested with restriction endonucleases and the RFLP products we

The structure of the protein was characterized using bioinfomatics approach and the activity of the enzyme under abiotic stresses was studied. An increase in the activity of ascorbate peroxidase was detected during desiccation of D. scoparium shoots.

AbstractImmunoglobulin (Ig) and T-cell receptor (TCR) gene rearrangements provide clonal markers useful for diagnosis and measurement of minimal residual disease (MRD) in acute lymphoblastic leukemia (ALL). We analyzed the sequences of Ig and TCR gene rearrangements obtained at presentation and relapse in 41 children with ALL to study clonal stability, which has important implications for monitoring MRD, during the course of the disease. In 42%, all original Ig and/or TCR sequences were conserved. In 24%, one original sequence was preserved but the other lost, and in 14% the original sequences

The diogenid hermit crab genus Clibanarius Dana, 1852 is a group of decapod crustaceans commonly found in tropical or subtropical shallow waters. The species of the genus are usually characterized by distinct color patterns in life, but the identification of colorless specimens preserved in ethanol is sometimes very difficult. DNA barcoding can facilitate species identification and recognition. In this study, we determined partial sequences of the cytochrome oxidase I (COI) gene of 11 Clibanarius species commonly found in the intertidal zones of the Ryukyu Archipelago, southwestern Japan.

CRISPR-Cas9 studies have implicated gene editing of DNA sequences for medical treatment of diseases such as sickle cell anemia, thalassemia, AIDS, blindness, muscular dystrophy, Huntington’s disease, and cystic fibrosis. Moreover, gene editing technology has contributed to the detection of viruses responsible for the dissemination of communicable diseases such as COVID-19. Despite current scientific progress, many uses of gene editing of DNA sequences are ethically questionable, bordering upon antithetical to principles of human rights protections.

Abstract:
Complementary DNA (cDNA) synthesis from RNA is a pivotal technique in molecular biology that enables the conversion of RNA molecules into DNA copies (Gubler, and Hoffman, 1983). This process holds immense significance in various research fields, including gene expression analysis, functional genomics, and molecular cloning. By synthesizing cDNA from RNA templates, researchers can access a stable DNA form of RNA sequences, allowing for easier manipulation, amplification, and analysis (Green, and Sambrook, 2012).

Abstract The Baculovirus Expression Vector System (BEYS) is an extremely versatile and powerful laboratory tool (1). In simplest terms, the BEYS allows the forced heterologous expression of recombinant protein in susceptible host strains of insect cells. Gene products from the simplest prokaryotes through to the higher eukaryotes have been expressed successfully in this system. Recombinant proteins are recovered in a folded and active form, and posttranslation modifications, such as phosphorylation, lipid acylation, and simple glycosylation are often preserved.

Nearly a dozen psalms might be classified as historical (or at least contain longer historical reflections or have the characteristics of the genre), and three examples are discussed in this chapter:
