A frameshift mutation that occurs very early in a protein sequence would have what effect on the protein's structure? A. The pri

AlekseyPX

Answer:

C. Primary, secondary, and tertiary structures would be altered

Explanation:

Frameshift mutations refer to the mutations that change the reading frame of the gene. Frameshift mutations are mostly caused by insertion or deletion of nucleotide since addition or loss of nucleotide alters all the codons present downstream of the point of the mutation site. If frameshift mutation occurs at the beginning of the protein sequence, all the downstream amino acids would be altered.

The changed amino acid sequence would alter the primary structure of the protein. Since the secondary and tertiary structure of proteins is determined by interactions between the R groups of amino acids, their polarity, charge, etc., the altered amino acid sequence would also alter secondary, and tertiary of the protein.

Answer:

Weight gain and depression are symptoms caused by imbalance of pituitary and adrenal glands and the cortisol hormone.

Explanation:

The pituitary gland is responsible for the overall functioning of the body since it produces a variety of hormones. It is very small in size and is also known as the 'master gland'. It is made of two parts- anterior pituitary gland and posterior pituitary gland. The pituitary gland and its functions are controlled by the hypothalamus.

The anterior pituitary secretes hormones which act on adrenal glands, thyroid, testes and ovaries. The hormones produced are TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone, etc.

Cortisol is produced by the adrenal gland under the command of pituitary gland. Cortisol helps in regulating blood sugar, blood pressure and helps in reducing inflammation. Any imbalance of adrenal gland will cause an increase or decrease in the production of cortisol. The symptoms produced on the imbalance are:

Obesity in upper body
High blood pressure
Mood swings, depression and irritability
Acne and other skin problems.
