What would happen if bicoid proteins were injected at the anterior end of a fruit fly embryo?

a. the embryo would have no dorsal-ventral axis.
b. anterior structures would form at both ends.
c. bicoid mrna wouldn’t be translated into protein.
d. the fly would develop normally.
e. posterior structures would form at both ends.

b

Explanation:

Anterior structures would be formed at both ends if bicoid proteins are injected in anterior end of fruit fly embryo.

Bicoid proteins inhibit the translation of caudal mRNA , so caudal proteins are formed only in posterior part.

Hence option B is correct

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
