Question
Chapter 27.3, Problem 1QC
Summary Introduction
To review:
Primitive streak and what does it establishes.
Introduction:
After the implantation of the blastocyst in the uterus, the embryonic period starts. It begins in the third week. During this stage, the conceptus is termed as an embryo and this period lasts up to 8 weeks. Before the process of gastrulation, the primitive streak develops.

Fig. 5-3: The Eco restriction site (left) would be cleaved at the locations indicated by the arrows.
However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI
One of the SNPs in B. rapa is found within the Park14 locus and can be detected
by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780
gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two
EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one
of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only
one EcoRI site (Fig. 5-3).

From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?

- What experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?arrow_forwardYou’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.arrow_forwardFor short answer questions, write your answers on the line provided.
