What specific type of experiment demonstrated that cadherins were sufficient to mediate cell-cell adhesion?
a) expression of a cadherin gene in cells that do not normally adhere to each other (or have low adhesion function)
b) cloning by screening an expression library rnai inhibition of cadherin function in developing frog embryos
c) using an antibody to block cadherin function mcb 252

Answer is A. Expression of Cadherin gene in the cell that do not normally adhere to each other( or have low adhesion function).

Explanation:

Not that, the level of Cadherin expression influences the streght of adhesion and the type of Cadherin expressed, in determining the specificity and property of interaction.

the backbone of the dna and rna compound is sugar phosphate.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
