Pls help ASAP. Use the info to ans the q. hext two questions.The lac operon is used in countless ways for genetics research and biotechnology.One important use of the lac operon is to regulate the expression of cloned genes. Inthis application, some regulatory elements of the operon are fused to the clonedgene that is to be regulated. One application of such technology was reported byCronin et al., The lac operator-repressor system is functional in the mouse, Genesand Development 15 (2001):1506-17. These investigators fused a portion of the lacoperon to the mouse tyrosinase gene, a gene required for pigment production. Thisrecombinant DNA, composed of E. coli lac operon sequences and the mousetyrosinase gene, was introduced into albino mice using techniques described inChapter 20. Using the lac operon regulatory sequences, the investigators were ableto regulate tyrosinase gene expression. In fact, they were able to convert albino(white) mice into brown mice. The following questions ask you to use yourknowledge of the lac operon to deduce how Cronin et al. were able to regulatetyrosinase gene expression in mice. Introducing the recombinant lac operon/mouse tyrosinase DNA into mice is only halfof the equation for regulating tyrosinase. In addition to lac operon/mouse tyrosinaseDNA, what other gene must be added to mice to regulate tyrosinase expression?the lacy genethe lac operatorthe lacl genethe lacZ gene4
