The coronavirus causing the COVID-19 pandemic, SARS-CoV-2, uses −1 programmed ribosomal frameshifting (−1 PRF) to control the relative expression of viral proteins. As modulating −1 PRF can inhibit viral replication, the RNA pseudoknot stimulating −1 PRF may be a fruitful target for therapeutics treating COVID-19. We modeled the unusual 3-stem stru...

Genetic code refers to a set of rules that assign trinucleotides called codons to amino acids in the process of protein synthesis. Investigating the genetic code's logic and its evolutionary origin has always been both intriguing and challenging. While the correspondence rules between codons and amino acids in the genetic code are well-known, it is...

DNA contains the genetic code, which provides complete information about the synthesis of proteins in every living cell. Each gene encodes for a corresponding protein but most of the DNA sequence is non-coding. In addition to this non-coding part of the DNA, there is another redundancy, namely a multiplicity of DNA triplets (codons) corresponding t...

Cancer chemotherapy agents are assessed for their therapeutic utility primarily by their ability to cause apoptosis of cancer cells and their potency is given by an IC50 value. Chemotherapy uses both target-specific and systemic-action drugs and drug combinations to treat cancer. It is important to judiciously choose a drug type, its dosage and sch...

By using the supersymmetry quantum mechanics method, we approximately solve the Dirac equation for the modified Eckart potential and the modified deformed Hylleraas including Coulomb-like tensor potential under spin and pseudospin symmetry. We obtained approximate energy eigenvalues and the corresponding wave functions in terms of the Jacobi polyno...

In the present letter, the relativistic equation for particle 1/2-spin have been obtained for the quadratic scalar and vector potentials in the presence of the tensor interaction that depends on the radial component either linearly and inversely. Under the spin symmetry, the relativistic equation is calculated by using the idea of L2 that supports...

In this work, exact solutions of the Dirac equation are studied for the pseudo-harmonic oscillatory ring-shaped potential by using the supersymmetry method. The un-normalized eigenfunctions and the eigenvalue equation of the Dirac equation are presented. Some numerical results are given. We also discuss the special cases of this potential. In addit...

We approximately solve the Dirac equation for attractive radial potential including a Coulomb-like tensor interaction under pseudospin and the spin symmetry limit for any arbitrary spin—orbit quantum number, by employing the supersymmetric (SUSY) quantum mechanics and supersymmetric shape invariance technique. We obtain the energy eigenvalue equati...

We solve the Dirac equation for Williams-Poulios and Tietz-Wei potentials including a Coulomb-like tensor interaction with arbitrary spin orbit quantum number , by employing supersymmetry shape invariance technique. We obtain the energy eigenvalues equation under the pseudospin condition. The calculated numerical results compare with obtained resu...
