cloning, Biology

Assignment Help:
there are a restriction map of a plasmid and a human gene of known sequence. Your task is to clone the human liver cDNA for this gene so that the start codon is closer to the EcoRI site than the PstI site of the polylinker/MCS, but you also need to get rid of the promoter+RBS+Hin insert already in the plasmid. Explain how you would accomplish the cloning using a series of numbered steps. Note that in the plasmid, the (1) refers to the frequency of these sites in the plasmid plus existing insert. In the gene’s restriction map, all the relevant restriction sites are indicated if they are present
