  2. Sequence diagram - Wikipedia

    en.wikipedia.org/wiki/Sequence_diagram

    The diagram emphasizes events that cross the system boundary from actors to systems. A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD): A regular version of sequence diagram describes how the ...

  3. 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 ...

  4. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. [2] [3] The mRNA sequence is determined by the sequence of ...

  5. Regulatory sequence - Wikipedia

    en.wikipedia.org/wiki/Regulatory_sequence

    Regulatory sequence in a promoter at a transcription start site with a paused RNA polymerase and a TOP2B-induced double-strand break. Such TOP2B-induced double-strand breaks are accompanied by at least four enzymes of the non-homologous end joining (NHEJ) DNA repair pathway (DNA-PKcs, KU70, KU80 and DNA LIGASE IV) (see figure). These enzymes ...

  6. Convolutional code - Wikipedia

    en.wikipedia.org/wiki/Convolutional_code

    An actual encoded sequence can be represented as a path on this graph. One valid path is shown in red as an example. This diagram gives us an idea about decoding: if a received sequence doesn't fit this graph, then it was received with errors, and we must choose the nearest correct (fitting the graph) sequence. The real decoding algorithms ...

  7. Barker code - Wikipedia

    en.wikipedia.org/wiki/Barker_code

    A Barker code or Barker sequence is a finite sequence of N values of +1 and −1, a j for j = 1 , 2 , … , N {\displaystyle a_{j}{\text{ for }}j=1,2,\dots ,N} with the ideal autocorrelation property, such that the off-peak (non-cyclic) autocorrelation coefficients

  8. Sequence logo - Wikipedia

    en.wikipedia.org/wiki/Sequence_logo

    A consensus logo is a simplified variation of a sequence logo that can be embedded in text format. Like a sequence logo, a consensus logo is created from a collection of aligned protein or DNA/RNA sequences and conveys information about the conservation of each position of a sequence motif or sequence alignment [1] [4].

  9. Genetic code - Wikipedia

    en.wikipedia.org/wiki/Genetic_code

    With some exceptions, [1] a three-nucleotide codon in a nucleic acid sequence specifies a single amino acid. The vast majority of genes are encoded with a single scheme (see the RNA codon table ). That scheme is often called the canonical or standard genetic code, or simply the genetic code, though variant codes (such as in mitochondria ) exist.
