DNA Replication
DNA replication is the process by which a cell duplicates its genome before cell division, ensuring each daughter cell receives an identical copy of the genetic material.
Nucleic acids DNA Structure and Topology
DNA is a double-stranded helix that stores genetic information, with its structure and topology being fundamental to its function in replication, transcription, and repair.
Nucleic acids Gene Regulation and Epigenetics
Gene regulation controls when, where, and how much a gene is expressed through the combined action of transcription factors, chromatin modifications, and non-coding RNAs.
Nucleic acids RNA Structure and Types
RNA is a versatile nucleic acid that functions in information transfer, catalysis, gene regulation, and cellular structure, existing in many distinct forms.
Nucleic acids Transcription and RNA Processing
Transcription is the synthesis of RNA from a DNA template, followed by extensive processing in eukaryotes including capping, splicing, and polyadenylation.
Nucleic acids Translation
Translation is the process by which the genetic code carried by mRNA is decoded by the ribosome to synthesize a polypeptide chain with a specific amino acid sequence.
Nucleic acids Amino Acid Catabolism & the Urea Cycle
Amino acid catabolism is the breakdown of amino acids, producing metabolic intermediates and nitrogen that is disposed of through the urea cycle.
Amino acids Isoelectric Point & Titration of Amino Acids
The isoelectric point is the pH at which an amino acid carries no net charge, determined by its ionizable groups and pKa values.
Amino acids Post-translational Modifications
Post-translational modifications are covalent changes to proteins after synthesis that regulate their function, localization, and stability.
