  2. Trans-splicing - Wikipedia

    en.wikipedia.org/wiki/Trans-splicing

    Trans-splicing is a special form of RNA processing where exons from two different primary RNA transcripts are joined end to end and ligated.It is usually found in eukaryotes and mediated by the spliceosome, although some bacteria and archaea also have "half-genes" for tRNAs.

  3. Protein splicing - Wikipedia

    en.wikipedia.org/wiki/Protein_splicing

    Protein splicing is an intramolecular reaction of a particular protein in which an internal protein segment (called an intein) is removed from a precursor protein with a ligation of C-terminal and N-terminal external proteins (called exteins) on both sides. The splicing junction of the precursor protein is mainly a cysteine or a serine, which ...

  4. History of genetic engineering - Wikipedia

    en.wikipedia.org/wiki/History_of_genetic_engineering

    e. Genetic engineering is the science of manipulating genetic material of an organism. The concept of genetic engineering was first proposed by Nikolay Timofeev-Ressovsky in 1934. [1] The first artificial genetic modification accomplished using biotechnology was transgenesis, the process of transferring genes from one organism to another, first ...

  5. CRISPR - Wikipedia

    en.wikipedia.org/wiki/CRISPR

    CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.

  6. Transposable element - Wikipedia

    en.wikipedia.org/wiki/Transposable_element

    A transposable element (TE), also transposon, or jumping gene, is a type of mobile genetic element, a nucleic acid sequence in DNA that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. [1][2] Transposition often results in duplication of the same genetic ...

  7. RNA splicing - Wikipedia

    en.wikipedia.org/wiki/RNA_splicing

    RNA splicing. RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre- mRNA) transcript is transformed into a mature messenger RNA (mRNA). It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions). For nuclear-encoded genes, splicing occurs in the ...

  8. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  9. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR gene editing. CRISPR-Cas9. CRISPR gene editing (CRISPR, pronounced / ˈkrɪspər / "crisper", refers to " c lustered r egularly i nterspaced s hort p alindromic r epeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial ...
