For example the validity of the branch arrangement in a predicted phylogenetic tree can be tested by resampling columns in a multiple sequence alignment to create many new alignments. The appearance of a particular branch in trees generated from these resampled sequences can then be measured Alternatively, a sequence may be left out of an analysis to deter-mine how much the sequence influences the results of an analysis Branch| ength(分支长度) In sequence analysis, the number of sequence changes along a particular branch of a phylogenetic tree CDS or cds(编码序列) Coding sequence Chebyshe, d inequality The probability that a random variable exceeds its mean is less than or equal to the square of 1 over the number of standard deviations from the mean Clone(克隆) Population of identical cells or molecules(e.g. DNA), derived from a single ancestor Cloning Vector(克隆载体 A molecule that carries a foreign gene into a host, and allows/facilitates the multiplication of that gene in a host.
