You've found a gene on chromosome 17 of a hirsute, belligerent Canadian that you believe is responsible for his remarkably fast and scarless healing. You want to study the protein product of this gene, which you've dubbed the X-gene. Your plan is to PCR amplify the X-gene from a sample of the Canadian's DNA and insert it into a vector suitable for human cells. This vector has an BamH1 restriction site to the left and a Pstl restriction site to the right of where you intend to place the X-gene. We're going to PCR amplify the X-gene from our sample of mutant DNA, editing in the appropriate restriction sites as we do. (The chromosomal DNA, like most DNA we sample from nature, doesn't have convenient restriction sites at the right and left of the sequence we're interested in.) The portion of the DNA on chromosome 17 with the X-gene in it is shown below. The reference strand is on top and the complement strand below, as usual. 5'-...ggcgccttcgggaaagggtaggctaagactXGENEgatgatcagtaagctattcgatctctggcgcg...-3′ 3'-...ccgcggaagccctttcccatccgattctgaXGENEctactagtcattcgataagctagagaccgcgc...-5' Fill in the sequence for the right (or reverse) primer ______ and the left (or forward) primer ______ that you would use to amplify the X-gene from the sample DNA and introduce the appropriate restriction sites. These primers should: • both be written 5' to 3' using lower-case letters • contain base pairs that are complementary to the DNA in red • introduce BamHI and Pstl restriction sites into the PCR amplified DNA that will appear in place of the DNA in blue • both have five extra bases on the 5' end, before the restriction site - exactly what bases those are isn't critical, so keep them as nnnnn. If you are colorblind and these color-coded instructions are difficult to parse, please email the instructor for an alternate version of the homework.

Bera and Chris decided that they no longer needed each other to grow their respective business and want to go their separate ways. Thus, they decided to effectuate the following transactions. a. On December 31, 2021, Lala Co incorporated the art collection business into Art Co and distributed the stock in Art Co to Chris in redemption of Chris' stock in Lala Co. What is this form of § 355 distribution? What are the tax consequences to the parties? b. Same as Problem 3.a except that Lala Co operated the business through Art Co in the inception, i.e., January 1, 2010. What are the tax consequences to the parties? c. Same as Problem 3a, except that a few months before the distribution, Bera sold 80 shares to Abby, an unrelated person. After the distribution, Bera owns 20% of the stock of Lala Co, Abby owns 80% of Lala Co stock, Chris owns no stock in Lala Co, and Chris owns 100% of the Art Co stock. Does the distribution of Art Co qualify for a § 355 distribution?
