What is the structure of a nucleotide? What does DNA polymerase bind to? What is a DNA-binding protein motif? What is the molecule rRNA a component of? What is single-stranded DNA-binding protein? How much energy is used to make the amino acid-tRNA bond?
What is a protein motif? What is semiconservative DNA replication? What type of bond holds the DNA bases together? What do single-stranded binding proteins do in DNA replication? What is global DNA methylation? What is the primary level of DNA structure?
The 伪-helical, coiled-coil protein motif is increasingly recognized in a variety of functional classes of proteins. The pitch of a coiled coil, or rate of winding of the 伪-helices around each other, is a key determinant of both intra- and intermolecular interactions. Experimental measurements...

The second mode called Structure, represent protein as ‘residue gas,’ where every amino acid is represented as a triangle, build from the N-Cα-C atoms that are displaced and rotated in space (affine matrices), and further refined with geometry-aware attention operation termed ‘invariant ...
What type of hybridisation is involved in the formation of theC≡Cbond? View Solution What type of bonding helps in stabilising theα−helixstructure of proteins? View Solution What type of bonding occurs in (a)α-helix configuration (b) proteins and (c)β-sheet ?
In any biological system with memory, the state of the system depends on its history. Epigenetic memory maintains gene expression states through cell generations without a change in DNA sequence and in the absence of initiating signals. It is immensely powerful in biological systems — it adds lon...
is regulated by binding to adaptor proteins through protein-protein interaction of death folds (a tertiary structure motif). Executioner caspases carry out the mass proteolysis that leads to apoptosis. These caspases can cleave a wide range of target proteins leading to apoptosis. Caspase-activated ...
a ‘vascular asymmetric appendicular structure initiated at the shoot apical meristem’. This definition is applicable to all vascular plants, but does not hold true for bryophytes (mosses, liverworts, and hornworts) as they lack a well-defined system of vascular tissue [1]. In fact, the leaf...
The interaction between receptors and Atg8/LC3/GABARAP proteins occurs through a short linear motif, called Atg8 interacting motif (AIM) or LC3 interacting region (LIR). Most AIM/LIRs consist of a short, conserved sequence, whose consensus is Θ-X-X-Γ, where Θ represents an aromatic amino...
