The diseases and conditions associated with the thyroid and the parathyroid gland. Introduction: Thyroid gland Is a large gland in the neck which is a cartilage of larynx. It is involved in secretion of hormones that helps in the regulation of body metabolism . Thyroid gland secretes: triidothyronine (T3) and thyroxine (T4). These hormones are important for the metabolism of the body. Also, it is important for the development and growth of the body. It controls the level of iodine in the body. The hormone calcitonin helps in the maintenance of blood calcium level. It plays important role in nerve conduction and muscle contraction. It also lowers the blood calcium level if it rises. Parathyroid glands are four small glands present in the neck. It helps in the control of calcium level of the body. These glands secrete parathyroid hormone (PTH). This hormone stimulates the activity of osteoclats that helps in the release of calcium ion from the bones. It also promotes the reabsorption of calcium ions by the kidney. This hormone helps in increasing the blood calcium level if it is low.

Introduction:

Thyroid gland Is a large gland in the neck which is a cartilage of larynx. It is involved in secretion of hormones that helps in the regulation of body metabolism. Thyroid gland secretes: triidothyronine (T3) and thyroxine (T4). These hormones are important for the metabolism of the body. Also, it is important for the development and growth of the body. It controls the level of iodine in the body. The hormone calcitonin helps in the maintenance of blood calcium level. It plays important role in nerve conduction and muscle contraction. It also lowers the blood calcium level if it rises.

Parathyroid glands are four small glands present in the neck. It helps in the control of calcium level of the body. These glands secrete parathyroid hormone (PTH). This hormone stimulates the activity of osteoclats that helps in the release of calcium ion from the bones. It also promotes the reabsorption of calcium ions by the kidney. This hormone helps in increasing the blood calcium level if it is low.

5G JA ATTC 3 3 CTIA A1G5 5 GAAT I I3 3 CTIA AA5 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?
