    In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team.

    [5] There are 64 different codons in the genetic code and the below tables; most specify an amino acid. [6] Three sequences, UAG, UGA, and UAA, known as stop codons, [note 1] do not code for an amino acid but instead signal the release of the nascent polypeptide from the ribosome. [7]

  4. Transcription error - Wikipedia

    en.wikipedia.org/wiki/Transcription_error

    Electronic transcription errors occur when the scan of some printed matter is compromised or in an unusual font – for example, if the paper is crumpled, or the ink is smudged, the OCR may make transcription errors when reading.

    en.wikipedia.org/.../SAT_Subject_Test_in_Biology_E/M

    The SAT Subject Test in Biology was the name of a one-hour multiple choice test given on biology by the College Board. A student chose whether to take the test depending upon college entrance requirements for the schools in which the student is planning to apply. Until 1994, the SAT Subject Tests were known as Achievement Tests; and from 1995 ...

    Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...

    en.wikipedia.org/wiki/Multiple_choice

    In this method, the score is reduced by the number of wrong answers divided by the average number of possible answers for all questions in the test, w/(c – 1) where w is the number of wrong responses on the test and c is the average number of possible choices for all questions on the test. [10] All exams scored with the three-parameter model ...

    en.wikipedia.org/wiki/Genetic_code

    This is known as the "frozen accident" argument for the universality of the genetic code. However, in his seminal paper on the origins of the genetic code in 1968, Francis Crick still stated that the universality of the genetic code in all organisms was an unproven assumption, and was probably not true in some instances.

    First, convert each template DNA base to its RNA complement (note that the complement of A is now U), as shown below. Note that the template strand of the DNA is the one the RNA is polymerized against; the other DNA strand would be the same as the RNA, but with thymine instead of uracil. DNA -> RNA A -> U T -> A C -> G G -> C A=T-> A=U
