Gel electrophoresis separates nucleic acids on the basis of differences in (a) length (molecular weight) (b) charge (c) nucleotide sequence (d) relative proportions of adenine and guanine (e) relative proportions of thymine and cytosine

8. NMR measurements have shown that poly-lysine is a random coil at pH 7 but becomes a helix when the pH is raised above 10. If the same type of folding behavior is observed, what should be the pH dependence of poly-glutamate? A) Helix at pH 7 but random coil at pH 10 B) Random coil at pH 3 but helix at pH 7 C) Random coil at pH 7 but helix at pH 10 D) Helix at pH 3 but random coil at pH 7

Biochemistry What would be the difference in the constructs produced from blunt-end ligation and sticky-end ligation (Hint: observe the orientation)? Which technique is better and why do you think so?

This technique does not provide atomic-level structures of proteins a)Circular dichroism b)Crystallography c)CryoEM d)Protein NMR e)Molecular dynamics simulations
