The Central Dogma of Molecular Biology explains how genetic information is stored in DNA, transcribed into RNA, and translated into proteins. Explore DNA replication, transcription, RNA processing, translation, gene regulation, genetic mutations, and modern extensions of the Central Dogma.

Pumilio repeats, also known as PUF repeats, form RNA-binding protein domains that recognize specific RNA sequences. These proteins regulate gene expression by influencing messenger RNA stability, translation, and other processes involved in cell development and function.

Valine is encoded by four mRNA codons—GUU, GUC, GUA, and GUG. Explore how valine is specified by the genetic code and how DNA, mRNA, tRNA, codon degeneracy, translation, mutations, and codon usage connect genetic information with protein synthesis.

RNA is a versatile nucleic acid involved in gene expression, protein synthesis, regulation, and catalysis. Explore RNA structure, nucleotide composition, base pairing, folding, RNA types, processing, and biological functions.

Introns are regions of genes that are transcribed into pre-mRNA but are usually removed during RNA splicing. Learn how introns differ from exons and how they influence gene expression, alternative splicing, and genetic disease.

Exons are regions of genes that remain in mature RNA after introns are removed during RNA splicing. Learn how exons contribute to mRNA, protein production, alternative splicing, genetic variation, and gene expression.

Codons and anticodons are essential to protein synthesis. Learn how mRNA codons and tRNA anticodons work together to translate genetic information into amino acid sequences and proteins.

The genetic code is the set of rules that allows cells to translate genetic information in DNA and RNA into proteins. Explore codons, transcription, translation, mutations, gene expression, evolution, biotechnology, and the importance of the genetic code in life science and genetics.

Ligases are enzymes that join DNA, RNA, and other biological molecules by forming new chemical bonds. Explore their roles in DNA replication, repair, recombination, genetics, molecular cloning, diagnostics, and biotechnology.

Hydrogen bonds are essential non-covalent interactions that influence water, proteins, DNA, RNA, genetics, molecular recognition, and many processes essential to life.

Cytosine is a pyrimidine base found in DNA and RNA and plays essential roles in genetic information, DNA replication, gene regulation, DNA methylation, mutations, epigenetics, and genome stability. This overview explores the biological importance of cytosine in genetics, molecular biology, genomics, and biotechnology.

Guanine is a purine nitrogenous base found in DNA and RNA and plays essential roles in genetic information, DNA replication, RNA biology, cellular signaling, nucleotide metabolism, and genome stability. This overview explores the structure and biological importance of guanine in genetics, molecular biology, genomics, and biotechnology.

Genetic material contains the biological information essential for life, heredity, development, and evolution. Learn how DNA and RNA store, transmit, and regulate genetic information.

RNA quality control protects cells from defective transcripts produced by errors in transcription, RNA processing, splicing, and translation. Learn how RNA surveillance, nonsense-mediated decay, the RNA exosome, and other degradation pathways maintain RNA integrity and cellular function.

RNA export and localization control where RNA molecules move and function inside cells. Learn how RNA processing, nuclear export, RNA-binding proteins, molecular motors, localization signals, and cellular compartments regulate RNA transport, translation, and gene expression.
