Answer:
The correct answer is option A
Explanation:
Hypoparaghyroidism occurs when thyroid gland produce little parathyroid hormone.
This is caused by:
1. Injury to the parathyroid glands during thyroid and neck surgery.
2. It is also caused by auto immune disorder. This is as a result when the body's natural defence against invading organisms starts to attack perfectly healthy tissues.
3. Congenital defects: This is as a result when infants are born without parathyroid tissue, that is ability to make thyroid glands or when the mother has hypoparathyroidism.
The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
