Background: Most of the amino acids are encoded by more than one codon, termed as synonymous codons. Synonymous codon usage is not random as it is unique to species. In each amino acid family, some synonymous codons are preferred and this is referred to as synonymous codon usage bias (SCUB). Trends associated with evolution of SCUB and factors influencing its diversification in plastomes of gen...

The article offers a solution to the problem of fast and efficient recognition coronavirus genus. For this purpose, authors apply virus genome targeting method based on use sufficiently short conserved N-gene nucleocapsid protein. Comparison codon frequency distributions in analyzed set 67 prototypical strains corresponding subgenus allows us recognize genus coronavirus. This paper proposes opt...

background : colorectal cancer is the second cause of mortality in developed countries. the p53gene and some of it's polymorphisms are among the causes for cancer development.the purpose of this study is to evaluate the relationship between the p53 codon 72 polymorphism in colorectal adenocarcinoma specimens compared with controls. materials and methods : we performed a case-control study among...

As synthetic biology advances, labeling of genes or organisms, like other high-value products, will become important not only to pinpoint their identity, origin, or spread, but also for intellectual property, classification, bio-security or legal reasons. Ideally information should be inseparably interlaced into expressed genes. We describe a method for embedding messages within open reading fr...

UNLABELLED Latent Kaposi's sarcoma-associated herpesvirus (KSHV) genomes encode a homolog of cellular FLICE-inhibitory proteins (termed v-FLIP) that activates NF-κB and can trigger important proinflammatory and antiapoptotic changes in latently infected cells. The protein is present at very low levels in infection and has generally been difficult to efficiently express in recombinant vectors. H...
