Cоmplete the fоllоwing pаrаgrаph by selecting the correct term for each blank: A researcher studies neural tube formation by injecting N-cadherin mRNA into the presumptive epidermis of a frog embryo. N-cadherin is not normally expressed in the epidermis, so this experiment involves [a] expression of N-cadherin. The injected mRNA is considered [b] because it originates outside of the organism. In contrast, in cells where it is naturally found, N-cadherin is termed an [c] factor.
