PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC) Password is the master password from which a derived key is generated; Salt is a sequence of bits, known as a cryptographic salt; c is the number of iterations desired; dkLen is the desired bit-length of the derived key; DK is the generated derived key
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
Replication of the low-copy-number ColIb-P9 depends upon Rep, which is produced by expression of the repZ gene. repZ expression requires formation of a pseudoknot in the mRNA. repZ is repressed by a small antisense Inc RNA, which binds to repZ mRNA, forms an Inc RNA-mRNA duplex, and prevents formation of the pseudoknot to inhibit repZ ...
The major enzymatic functions carried out at the replication fork are well conserved from prokaryotes to eukaryotes, but the replication machinery in eukaryotic DNA replication is a much larger complex, coordinating many proteins at the site of replication, forming the replisome. [1]
HKDF-Extract takes "input key material" (IKM) such as a shared secret generated using Diffie-Hellman, and an optional salt, and generates a cryptographic key called the PRK ("pseudorandom key"). This acts as a "randomness extractor", taking a potentially non-uniform value of high min-entropy and generating a value indistinguishable from a ...
Being the primary holoenzyme involved in replication activity, the DNA Pol III holoenzyme also has proofreading capabilities that corrects replication mistakes by means of exonuclease activity reading 3'→5' and synthesizing 5'→3'. DNA Pol III is a component of the replisome, which is located at the replication fork.
Thomae's function: is a function that is continuous at all irrational numbers and discontinuous at all rational numbers. It is also a modification of Dirichlet function and sometimes called Riemann function. Kronecker delta function: is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise.
