Bicoid mRNA is expressed in a gradient in Drosophila embryos. Loss of Bicoid function leads to embryos with two posterior ends. If researchers injected bicoid mRNA into the posterior end of an embryo with no bicoid function, the embryo would most likely develop _.

A normally B with two posterior ends C with two anterior ends D with no anterior-posterior body axis

Brenden Mccann · Answer 1

Option (C) is Right Answer

Explanation:

C with two anterior ends

Bicoid mRNA is actively limited to the anterior of the organic product fly egg during oogenesis along microtubules by the engine protein dynein, and held there through relationship with cortical actin Interpretation of bicoid is managed by its 3' UTR and begins after egg deposition The posterior region (counting the hindgut) grows and stretches out towards the anterior pole along the dorsal side of the incipient organism Segments of the incipient organism become noticeable, making a striped course of action along the anterior-posterior axis
