Core residues are often conserved in a protein family, whereas the residues in loops are less conserved, unless they are involved in the protein's function. Protein tertiary structure can be divided into four main classes based on the secondary structural content of the domain. [25] All-α domains have a domain core built exclusively from α ...
Nucleic acids were first discovered in 1868 by Friedrich Miescher, [13] and by 1939, RNA had been implicated in protein synthesis. [14] Two decades later, Francis Crick predicted a functional RNA component which mediated translation; he reasoned that RNA is better suited to base-pair with an mRNA transcript than a pure polypeptide.
A mitogen-activated protein kinase (MAPK or MAP kinase) is a type of serine/threonine-specific protein kinases involved in directing cellular responses to a diverse array of stimuli, such as mitogens, osmotic stress, heat shock and proinflammatory cytokines.

They are offered as an alternative to industry-standard 2.5" NVMe SSDs in selected arrays from the IBM FlashSystem family, with raw storage capacities of 4.8 TB, 9.6 TB, 19.2 TB and 38.4 TB. FlashCore modules support hardware self-encryption and real-time inline hardware data compression up to 115.2 TB address space, without performance impact.
A module is called flat if taking the tensor product of it with any exact sequence of R-modules preserves exactness. Torsionless A module is called torsionless if it embeds into its algebraic dual. Simple A simple module S is a module that is not {0} and whose only submodules are {0} and S. Simple modules are sometimes called irreducible. [5 ...
