  2. Exon - Wikipedia

    en.wikipedia.org/wiki/Exon

    In protein-coding genes, the exons include both the protein-coding sequence and the 5′- and 3′-untranslated regions (UTR). Often the first exon includes both the 5′-UTR and the first part of the coding sequence, but exons containing only regions of 5′-UTR or (more rarely) 3′-UTR occur in some genes, i.e. the UTRs may contain introns. [11]

  3. Exon shuffling - Wikipedia

    en.wikipedia.org/wiki/Exon_shuffling

    It is a process through which two or more exons from different genes can be brought together ectopically, or the same exon can be duplicated, to create a new exon-intron structure. [1] There are different mechanisms through which exon shuffling occurs: transposon mediated exon shuffling, crossover during sexual recombination of parental genomes ...

  4. Alternative splicing - Wikipedia

    en.wikipedia.org/wiki/Alternative_splicing

    Alternative splicing produces three protein isoforms.Protein A includes all of the exons, whereas Proteins B and C result from exon skipping.. Alternative splicing, alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants.

  5. Intron - Wikipedia

    en.wikipedia.org/wiki/Intron

    The non-intron sequences that become joined by this RNA processing to form the mature RNA are called exons. [3] Introns are found in the genes of most eukaryotes and many eukaryotic viruses, and they can be located in both protein-coding genes and genes that function as RNA (noncoding genes). There are four main types of introns: tRNA introns ...

  6. Coding region - Wikipedia

    en.wikipedia.org/wiki/Coding_region

    The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...

  7. Genetic code - Wikipedia

    en.wikipedia.org/wiki/Genetic_code

    The code emerges at a transition when the mapping of codons to amino acids becomes nonrandom. The code's emergence is governed by the topology defined by the probable errors and is related to the map coloring problem. [109] Game theory: Models based on signaling games combine elements of game theory, natural selection and information channels ...

  8. Post-transcriptional modification - Wikipedia

    en.wikipedia.org/wiki/Post-transcriptional...

    RNA splicing is the process by which introns, regions of RNA that do not code for proteins, are removed from the pre-mRNA and the remaining exons connected to re-form a single continuous molecule. Exons are sections of mRNA which become "expressed" or translated into a protein. They are the coding portions of a mRNA molecule. [6]

  9. Exon skipping - Wikipedia

    en.wikipedia.org/wiki/Exon_skipping

    Exon skipping is used to restore the reading frame within a gene. Genes are the genetic instructions for creating a protein, and are composed of introns and exons.Exons are the sections of DNA that contain the instruction set for generating a protein; they are interspersed with non-coding regions called introns.
