Akey to recombinant dna technology (genetic engineering) is the ability to cut dna at specific sites. in a genome with 50% gc content, a restriction endonuclease with a 6-base pair recognition site (such as ecori, that cuts at gaattc) will cut, on average, once every nucleotides. answer with a whole number to fill in the blank.
