Answer and Explanation:
The steps for construction of the expression plasma
- STEP 1 : Introducing Notl and Hindlll confinement sites at the ends of the gene of interest by means of PCR
- STEP 2 :Digest the plasmid and DNA encoding gene with the Notl and Hindol confinement endonucleuses.
- STEP 3 : Ligate the cut plasmid and DNA fragment
- STEP 4 : Change the plasmid into E.coli for expression
- STEP 5 : Clean the protein by utilizing a column of immobilized

Spiders do not have muscles for extending the legs at these joints. Spiders, like most creatures, desiccate upon death, losing their waters, explaining why spider legs curl up upon death.
