The rest of the quiz questions will build off of the scenario below.

Gordita and Quesarito are two maternal gene proteins that establish the anterior/posterior axis of the developing X. mutans. Gordita levels are highest at the anterior of the animal while Quesarito is highest in the posterior; both proteins exist as a gradient.

Just based on this information, which of the following toolkit genes would be most likely to be expressed in the middle region of the developing X. mutans?

gene N: Gordita promotes expression while Quesarito represses expression

gene F: Quesarito represses expression

gene C: low levels of both Quesarito and Gordita promote transcription

gene A: Quesarito promotes while Gordita represses transcription

Answer #1

Ans: gene C: low levels of both Quesarito and Gordita promote transcription

Explanation: As protein level is found in gradient, in the middle region protein level of both genes is low. So, low level of both Quesarito and Gordita promote transcription.

How does this maternal information get transmitted to the embryo? During egg development, pieces of maternal DNA are moved into the embryo to temporarily allow transcription and translation of maternal DNA During egg development, proteins transcribed and translated in maternal nurse cells are moved into the embryo During egg...

    Developmental Biology Help! Please answer all the questions 1) We discussed the fact that each stripe expression pattern is affected by the enhancer region that is utilized. Knowing that the maternal genes and the gap genes can both contribute to the pair-rule genes, and that in many cases multiple stripes may be contained in one area of GAP, how does the embryo have definition of stripes if all of these transcription factors can be within the same cell A it...

The expression of the normal (wild type) operon is given. Note that "ON" and "OFF" refer to whether the operon is expressed at high levels (ON) or basal//low/no levels (OFF). (Hint: mutations render the indicated site inactive while leaving the remaining part of the operon or protein functional.) Note...

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
