Yeah if it would have been same length then it would have been easy to make map....that's what is confusing me. Isolated gene from an EcoR I digest contains a single Asp 1 restriction site but no other restriction sites.The gene is inserted into a plasmid digested with Ecor 1 and the plasmid with th...

This is my assignment. A pure protein was subjected to N-terminal analysis using c14-phenyl isothiocyanate,specific activity 120ci/mole.Reaction of the reagent with 2.3microgram of protein produced 12,300 cpm PTH-met and 8200 cpm PTH-val with a 90% counting efficiency.Calculate molecular weight of p...
