A thermophillic bacterium was isolated from a hot spring at Perak to study its thermostable amylase gene. Before the gene could be cloned for further work, the genome of this bacteria should first be extracted. (i) State FOUR (4) main methods you may use to lyse the cells prior to DNA isolation. Give ONE (1) example of each method. (ii) After the genome is obtained, explain in detail how the amylase gene could be cloned into Escherichia coli competent cells to be amplified.
