A class of enzymes that perform this process with a catalytic serine residue is exemplified by Bxb1 and PhiC31 (10[1])and is used to deliver large cargo. An enzyme that performs this process is delivered alongside various fluorescent proteins to visualize the connectome in Brainbow imaging. This process can be encouraged by knocking out Ku·70 and Ku·80 (10[1])to inhibit a different process from competing with this one during CRISPR knock-in experiments. This process is (10[1])performed by a non-chaperone (10[1])enzyme that, when attached to an estrogen receptor, creates an inducible (10[1])gene expression system controlled by tamoxifen. This process is localized to LoxP sites (10[2])in a site-specific (10[1])variant (10[1])of this process (10[2])driven by (-5[1])the enzyme Cre (-5[1])(“cree”). For 10 points, name this process in which two homologous strands of DNA exchange sequences (10[2])with (10[1])each other. (10[1])■END■ (10[3]0[3])
