摘要:
Methods are disclosed herein for inducing homologous recombination in a host cell comprising a target nucleic acid, using a single-stranded nucleic acid molecule. The single-stranded nucleic acid molecule has a sufficient number of nucleotides homologous to the target nucleic acid to enable homologous recombination with the target nucleic acid. The host cell includes a de-repressible promoter operably linked to a nucleic acid encoding a single-stranded binding protein and is deficient for mismatch repair. Isolated host cells of use in this method are also disclosed.

摘要:
A method and apparatus for character entry and more particularly Chinese character entry. The method improves the ease of entry for Chinese characters on a device that has a keypad arrangement of at least a 3×3 matrix (106). For example wireless communication devices such as radiotelephones have a keypad (108) for dialing phone numbers. Arranging the Chinese characters on the device display in a 3×3 matrix to match the at least 3×3 matrix of the keypad allows the user to quickly select from the pin yin list (104) the key on the keypad that corresponds to the desired character in the matching matrix.
