    Quizlet was founded in 2005 by Andrew Sutherland as a studying tool to aid in memorization for his French class, which he claimed to have "aced". [6] [7] [8] ...

  4. Spliceosome - Wikipedia

    en.wikipedia.org/wiki/Spliceosome

    Alternative splicing (the re-combination of different exons) is a major source of genetic diversity in eukaryotes. Splice variants have been used to account for the relatively small number of protein coding genes in the human genome , currently estimated at around 20,000.

  5. Hypothetical types of biochemistry - Wikipedia

    The possibility of life-forms being based on "alternative" biochemistries is the topic of an ongoing scientific discussion, informed by what is known about extraterrestrial environments and about the chemical behaviour of various elements and compounds. It is of interest in synthetic biology and is also a common subject in science fiction.

    Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...

    An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence.

  8. Autapomorphy - Wikipedia

    en.wikipedia.org/wiki/Autapomorphy

    Phylogenies showing the terminology used to describe different patterns of ancestral and derived character or trait states. [1]In phylogenetics, an autapomorphy is a distinctive feature, known as a derived trait, that is unique to a given taxon.

  9. Open reading frame - Wikipedia

    en.wikipedia.org/wiki/Open_reading_frame

    An alternative definition says that an ORF is a sequence that has a length divisible by three and is bounded by stop codons. [1] [4] This more general definition can be useful in the context of transcriptomics and metagenomics, where a start or stop codon may not be present in the obtained sequences. Such an ORF corresponds to parts of a gene ...
