The correct answer is uncompensated respiratory acidosis.
This is a condition in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide (CO2) in the blood which causes the pH of blood and to decrease (becomes acidic. Acidosis occurs because restoration of normal acid-base balance is not possible or has not yet been achieved. Uncompensated acidosis is characterized by abnormal pH and abnormal values of PaCO2 or HCO3.
Answer/Explanation:
Telomeres are structures found at the end of the chromosomes. They are protective structures made of repetitive sequences. They protect chromosomes from damage or fusing with other chromosomes. As the cell divides and divides, telomeres shorten. When they reach a critical point, the cell stops dividing, and might even undergo apoptosis (die).
Telomerase is an enzyme that adds nucleotides to telomeres to prevent their shortening. If all our cells expressed telomerase, the telomeres would never reach the critical short length to stop cell division. Therefore, our cells would keep dividing forever!
<span>Other mutagens act by chemically modifying the bases of DNA. For example, nitrous acid (HNO2) reacts with bases that contain amino groups. Adenine is oxidatively deaminated to hypoxanthine, cytosine to uracil, and guanine to xanthine. ... Uracil pairs with adenine rather than with guanine.</span><span>
