Draw (or arrange) only the items you need from
the Lab Materials Page (picture below) in the
order you would use them to make AND screen a gene library.
You will ‘draw’ the steps that use the Lab Materials in the correct
order to create and screen a gene library which has the assigned
gene clone. You will need to add some connecting words and phrases
to make all the steps for making your library clear.

Below is a set of experiments for cloning the human growth hormone (HGH) gene and then expressing the HGH protein in E. coli starting from human pituitary glands and a tube of plasmid vector DNA. The plasmid expression vector contains the arabinose inducible expression system. Specify the correct order for carrying out these experiments, using the letter codes in front of each procedure. Use all of the steps in your answer, except for one step that should NOT be included....

Section C (40 marks) Answer ALL questions from this Section 5. You have isolated total RNA from muscle cells and constructeda muscle cDNA library. You wish to study the regulatory region of a muscle-specific cDNA gene (gene M) that you have previously identified. 6 (a) For your study, you need to isolate a genomic clone of gene M. Why isa cDNA clone of gene M not appropriate for your study? (2 marks) (b) Outline the steps you would...

QUESTION 1: You are inserting a gene into an MCS found within the LacZ gene. Using blue/white colony selection, why could you assume that white colonies have modified plasmids? a. A blue colony means the LacZ reading-frame was disrupted b. A blue colony means your gene has mutations c. A white colony means the LacZ reading-frame is intact d. A white colony means the LacZ reading-frame was disrupted QUESTION 2: You are performing a PCR using primers with a sequence perfectly...
