High efficiency family shuffling based on multi-step PCR and in vivo DNA recombination in yeast: statistical and functional analysis of a combinatorial library between human cytochrome P450 1A1 and 1A2.

abstract：:The nucleotide sequence of the Anacystis nidulans 23S rRNA gene, including the 5'- and 3'-flanking regions has been determined. The gene is 2876 nucleotides long and shows higher primary sequence homology to the 23S rRNAs of plastids (84.5%) than to that of E. coli (79%). The predicted rRNA transcript also shares many...
