To label: The heart structures in Figure 27.2(a)
Introduction: The heart is the muscular organ that weighs about the size of the fist. The main function of the heart is to transport the oxygenated blood to all parts of the body. It consists of four chambers namely right atrium, left atrium, right ventricle, and left ventricle. The blood vessels called arteries and veins are involved in the transport of blood to the tissues and from tissues to the heart.

Answer to Problem 1.1BGL
Pictorial representation:
Fig 1: The anterior view of the heart.
Explanation of Solution
The structures of the anterior view of the heart is reviewed as follows:
Right auricle: It is the muscular cone shaped pouch that is attached to the right atrium of the heart. It is also called as right atrial appendage.
Cononary sulcus: It is the structure that separates the atrium of the heart from the ventricles. There are two coronary sulcus present in the heart namely right coronary sulcus and left coronary sulcus.
Right ventricle: It is one of the four heart chambers. It plays an important role in carrying the deoxygenated blood from the heart to the lungs.
Left auricle: It is the muscular cone shaped pouch that is attached to the anterior surface of the left atrium of the heart. It functions in increasing the pumping capacity of the left atrium.
Anterior interventricular sulcus: The heart consists of two interventricular sulcus namely anterior interventricular sulcus and posterior interventricular sulcus. It plays an important role in separating the ventricles of the heart.
Left ventricle: It is one of the four heart chambers. It plays an important role in carrying the oxygenated blood to all parts of the body.
Apex of heart: It is present in the left side of the heart between the fourth and fifth ribs. It consists of the left ventricle. It plays an important role in regulating the contraction of the ventricles.

Answer to Problem 1.1BGL
Pictorial representation:
Fig 2: The posterior view of the heart.
Explanation of Solution
The structures of the posterior view of the heart is reviewed as follows:
Left atrium: It is one of the four heart chambers. The oxygenated blood from the lungs enters into the left atrium.
Coronary sulcus: It is the structure that separates the atrium of the heart from the ventricles. There are two coronary sulcus present in the heart namely right coronary sulcus and left coronary sulcus.
Left ventricle: It is one of the four heart chambers. It plays an important role in carrying the oxygenated blood to all parts of the body.
Adipose tissue: The adipose tissue that surrounds the heart plays an important role by acting as cushion and insulates the heart.
Posterior interventricular sulcus: The heart consists of two interventricular sulcus namely anterior interventricular sulcus and posterior interventricular sulcus. It plays an important role in separating the ventricles of the heart.
Right atrium: It is one of the four chambers of the heart that receives the deoxygenated blood from the vena cava and pumps to the right ventricle.
Right ventricle: It is one of the four chambers of the heart that sends blood to the lungs to get oxygenated through the pulmonary arteries.

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?arrow_forwardWhat 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_forward
