Sequence motif

In genetics, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and has, or is conjectured to have, a biological significance. An example is the N-glycosylation site motif: Asn, followed by anything but Pro, followed by either Ser or Thr, followed by anything but Pro where the three-letter abbreviations are the conventional designations for amino acids (see genetic code).

When a sequence motif appears in the exon of a gene, it may encode the "structural motif" of a protein; that is a stereotypical element of the overall structure of the protein. Nevertheless, motifs need not be associated with a distinctive secondary structure. "Noncoding" sequences are not translated into proteins and nucleic acids with such motifs need not deviate from the typical shape (e.g. the "B-form" DNA double helix). Outside of gene exons, there exist regulatory sequence motifs and motifs within the "junk," such as sate ...

Sequencing - Overview. In genetics terminology, DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. Currently, almost all DNA sequencing is performed using the chain termination method[1], developed by Frederick Sanger. This technique uses sequence-specific termination of an in vitro DNA synthesis reaction using modified nucleotide substrates. See also:

DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. Currently, almost all DNA sequencing is performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of an DNA synthesis reaction using modified nucleotide substrates. The sequence of DNA encodes the necessary information for living things to survive and reproduce. Determining the sequence is therefore useful in 'pure' research into why and how organisms live, as well as in applied ...

Methods for performing protein sequencing include: Edman degradation Peptide mass fingerprinting Mass spectrometry Protease digests If the gene encoding the protein can be identified it is currently much easier to sequence the DNA and infer the protein sequence. Determining part of a protein's amino-acid sequence (often one end) by one of the above methods may be sufficient to enable the identification of a clone carrying the gene. ...
