Question

Brutus Buckeye, a budding developmental biologist, has identified the football gene in ladybugs, and thinks that football is a ladybug version of bicoid. Which of the following data, if obtained, would provide evidence that football is the ladybug version of bicoid? A football-GFP fusion protein would be primarily located near the posterior end. RNA interference directed at football generates a ladybug embryo with two posterior ends. In situ hybridization shows football mRNA concentrated at the posterior end O A null mutation in football generates a ladybug embryo with two anterior ends.

Answer 1

Option 1 is the answer.

Bicoid type means genes whose proteins concentration is expressed in gradient along anterior posterior axis. So,tagging with GFP,gives idea where it is concentrated,whether gradient is there or not.
