Cyclin-dependent kinase 5. Cyclin-dependent kinase 5 is a protein, and more specifically an enzyme, that is encoded by the Cdk5 gene. It was discovered 15 years ago, and it is saliently expressed in post-mitotic central nervous system neurons (CNS). The molecule belongs to the cyclin-dependent kinase family.
A cyclin-dependent kinase inhibitor (CKI) is a protein that interacts with a cyclin-CDK complex to inhibit kinase activity, often during G1 phase or in response to external signals or DNA damage. In animal cells, two primary CKI families exist: the INK4 family (p16, p15, p18, p19) and the CIP/KIP family (p21, p27, p57).
Gene targeting. Gene targeting is a biotechnological tool used to change the DNA sequence of an organism (hence it is a form of Genome Editing ). It is based on the natural DNA-repair mechanism of Homology Directed Repair (HDR), including Homologous Recombination. Gene targeting can be used to make a range of sizes of DNA edits, from larger DNA ...

CRISPR gene editing. CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈkrɪspər / "crisper", refers to " c lustered r egularly i nterspaced s hort p alindromic r epeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial ...
At the conclusion of its fifth rate-setting policy meeting of 2024 on July 31, 2024, the Federal Reserve left the federal funds target interest rate at a 23-year high of 5.25% to 5.50% for an ...
Loop-mediated isothermal amplification (LAMP) primers [1] Loop-mediated isothermal amplification (LAMP) product [1]. In LAMP, the target sequence is amplified at a constant temperature of 60–65 °C (140–149 °F) using either two or three sets of primers and a polymerase like Bst Klenow fragment with high strand displacement activity in addition to a replication activity.
The test results found that 40-year-old Khloe has the cellular age of a 28-year-old, while 43-year-old Kim has the biological age of a 34-year-old. “Never in a million years!” Khloé said.
