DNA polymerase is an enzyme responsible for synthesizing new DNA strands during replication by adding nucleotides to a pre-existing strand using the original DNA as […]
RNA polymerase is an enzyme that synthesizes RNA from a DNA template during transcription. It binds to specific regions of the DNA called promoters and […]
Molecular chaperones are proteins that assist in the proper folding, assembly, and stabilization of other proteins. They prevent misfolding and aggregation, guide proteins to their […]
Caspases are a family of protease enzymes that play essential roles in apoptosis (programmed cell death) and inflammation. They cleave specific proteins at aspartic acid […]
Chargaff’s rule states that in DNA, the amount of adenine (A) equals thymine (T), and the amount of cytosine (C) equals guanine (G). This principle […]
Post-translational modifications occur after protein synthesis. They include phosphorylation, glycosylation, and acetylation, altering protein structure and function. These modifications regulate protein activity, localization, and stability, […]
Post-transcriptional modification refers to alterations made to mRNA molecules after transcription but before translation in eukaryotic cells. These modifications include 5′ capping, 3′ polyadenylation, and […]
DNA replication in eukaryotes involves initiation at multiple origins, proceeding bidirectionally from replication forks. Enzymes like DNA polymerases synthesize new strands, while helicases unwind the […]
