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 acidsDNA 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 acidsGene 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 acidsRNA 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 acidsTranscription 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 acidsTranslation
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 acidsAmino 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 acidsAmino Acid Synthesis
Amino acid synthesis pathways describe how organisms produce amino acids from metabolic precursors.
Amino acidsAmino Acids & their Properties
Amino acids are the building blocks of proteins, each with unique side chains that determine their chemical properties.
