  2. Protein sequencing - Wikipedia

    en.wikipedia.org/wiki/Protein_sequencing

    Protein sequence interpretation: a scheme new protein to be engineered in a yeast. It is often desirable to know the unordered amino acid composition of a protein prior to attempting to find the ordered sequence, as this knowledge can be used to facilitate the discovery of errors in the sequencing process or to distinguish between ambiguous results.

  3. List of unsolved problems in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Unsolved problems relating to the structure and function of non-human organs, processes and biomolecules include: Korarchaeota (archaea). The metabolic processes of this phylum of archaea are so far unclear. Glycogen body. The function of this structure in the spinal cord of birds is not known. Arthropod head problem. A long-standing zoological ...

  4. List of unsolved problems in chemistry - Wikipedia

    Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?

    en.wikipedia.org/wiki/BLAST_(biotechnology)

    On the other hand, the program XNU is used to mask off the tandem repeats in protein sequences. Make a k-letter word list of the query sequence. Take k=3 for example, we list the words of length 3 in the query protein sequence (k is usually 11 for a DNA sequence) "sequentially", until the last letter of the query sequence is included. The ...

  7. De novo peptide sequencing - Wikipedia

    en.wikipedia.org/wiki/De_novo_peptide_sequencing

    In mass spectrometry, de novo peptide sequencing is the method in which a peptide amino acid sequence is determined from tandem mass spectrometry. Knowing the amino acid sequence of peptides from a protein digest is essential for studying the biological function of the protein. In the old days, this was accomplished by the Edman degradation ...

  8. Bioinformatics - Wikipedia

    en.wikipedia.org/wiki/Bioinformatics

    Development of new mathematical algorithms and statistical measures to assess relationships among members of large data sets. For example, there are methods to locate a gene within a sequence, to predict protein structure and/or function, and to cluster protein sequences into families of related sequences.

  9. Sequencing - Wikipedia

    en.wikipedia.org/wiki/Sequencing

    In genetics and biochemistry, sequencing means to determine the primary structure (sometimes incorrectly called the primary sequence) of an unbranched biopolymer.Sequencing results in a symbolic linear depiction known as a sequence which succinctly summarizes much of the atomic-level structure of the sequenced molecule.
