Itâs easy to remember the meaning of imbalance when you break the word into parts. You might recognize the prefix im-as a way to say ânot.â Combine that with the familiar word balance, and you come up with something that is decidedly out of whack, or not balanced.
DNA Pattern Find. DNA Pattern Find accepts one or more sequences along with a search pattern and returns the number and positions of sites that match the pattern. Use DNA Pattern Find to locate sequence regions that match a consensus sequence of interest. Paste a raw sequence or one or more FASTA sequences into the text area below. White space and digits are removed before the pattern matching is performed. Input limit is 500000 characters.
Sequencing DNA means determining the order of the four chemical building blocks - called bases - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off. In addition, and importantly, sequence data can highlight changes in a gene that may cause disease. In the DNA double helix, the four chemical bases always bond with the same partner to form base pairs. Adenine (A) always pairs with thymine (T); cytosine (C) always pairs with guanine (G). This pairing is the basis for the mechanism by which DNA molecules are copied when cells divide, and the pairing also underlies the methods by which most DNA sequencing experiments are done.
