Chromatographic studies of nucleic acids. 4. The nucleic acid of the turnip yellow mosaic virus including a note on the nucleic acid of the tomato bushy stunt virus.

The nucleic acid of African Horse-Sickness Virus

Reverse transcription of turnip yellow mosaic virus RNA primed with calf-thymus DNA hydrolysate: characterization of the purified cDNA product.

Complementary DNA was transcribed from turnip yellow mosaic virus RNA, using the method of Taylor et al. (1). The purified cDNA thus obtained sedimented between 2 and 4 S and was a mostly uniform transcript of template RNA. It hybridized with a sharp transition to homologous TYMV-RNA (Crt 1/2 = 2.7 x 10(-2)), but showed a low level of hybridization (less than 5%) to the RNAs of two other tymovi...

A Novel Genetic classification of SARS coronavirus-2 following whole nucleic acid and protein alignment of the isolated viruses

Background and aims: The end of 2019 has marked the year, which the human population encountered a novel virus; SARS-CoV-2 that causes a disease namely COVID-19. Here we focused on the genome and protein mutations and subsequently suggested a new classification of the SARS-CoV-2. Materials and Methods: Our study showed that some extra positions in the virus genome play a key role in the SARS-C...

Cucumber Necrosis Virus Is a Member of the Tombusvirus Group

The electrophoretic patterns of dsRNA species isolated from cucumber plants infected with cucumber necrosis virus (CNV) and from Nicotiana clevelandii plants infected with tomato bushy stunt virus (TBSV) were almost identical and differed greatly from the electrophoretic patterns of dsRNA species isolated from tobacco plants infected with tobacco necrosis virus (TNV). Hybridization with cloned ...

Cellular Morphology and Immunologic Properties of Escherichia coli Treated With Antimicrobial Antisense Peptide Nucleic Acid

  Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...
