Answer: B. DNA polymerase checks for errors in base pairing as it helps new DNA strands form.
Explanation: DNA polymerase is an enzyme that catalyzes the synthesis of a new DNA strand from a DNA template. This process is known as replication. During replication, DNA polymerase rejects incorrect bases before the phosphodiester bond is formed because it has a 3' -> 5' exonuclease activity that double checks every nucleotide that is added to the growing strand. This check allows the enzyme to remove a newly added mismatched base pair.
Answer:
Homeostasis imbalance
Explanation:
Homeostasis is the ability of an organism to maintain stable internal environment. It is one of the major life functions. For example, the body has a way of regulating excess water in the body in form release of urine.
When the internal enviroment is not in equilibrium, it is called a homeostasis imbalance. It occurs when an organism is no longer able to maintain a fairly stable internal environment. Most this results as a result of diseases in the human body.
