Which of the following describes a characteristic of cancer cells?

Maintaining specialized cell functions

Loss of contact inhibition

Ability to repair DNA damage

Orderly cell cycle progression

Answer and Explanation

The Correct Answer is B

A.   Cancer cells typically lose their specialized functions and characteristics that normal cells have. This loss of differentiation is known as dedifferentiation, where cancer cells become less specialized and more primitive in nature. This allows them to proliferate rapidly and invade surrounding tissues.
B.   Contact inhibition refers to the normal process where cells stop dividing when they come into contact with neighboring cells. In cancer cells, this mechanism is disrupted, leading to uncontrolled cell growth and proliferation. Cancer cells continue to divide and grow even when they are in close contact with other cells, which contributes to tumor formation and progression.
C.   Cancer cells often acquire mutations that impair their ability to repair DNA damage effectively. This can lead to an accumulation of genetic mutations over time, which is a hallmark of cancer development. While some cancer cells may still have mechanisms to repair DNA damage, they are often less efficient compared to normal cells, leading to genomic instability and further mutation accumulation.
D.   Normal cells follow a tightly regulated cell cycle with specific checkpoints that ensure orderly progression through phases such as G1, S, G2, and M phases. In contrast, cancer cells often have dysregulated cell cycle control. They may bypass checkpoints that normally control cell division, leading to uncontrolled proliferation and growth.

Correct Answer is C

Explanation

A. Most individuals with Bell's palsy experience gradual improvement within weeks to months, and the majority recover completely. Permanent facial paralysis is rare, but some individuals may have residual mild weakness or asymmetry.
B. This statement is not typically true for Bell's palsy. Antibiotic eye drops are not routinely prescribed unless there is evidence of corneal exposure due to incomplete eyelid closure (lagophthalmos). Instead, artificial tears and lubricating ointments are often recommended to prevent dryness and protect the cornea.
C. In Bell's palsy, weakness or paralysis of the facial muscles can lead to inability to fully close the eyelid on the affected side. Taping the eyelid closed at night helps prevent corneal damage from exposure and dryness.
D. This statement is not recommended. It is important to avoid stressing the affected facial muscles excessively during recovery from Bell's palsy. Chewing evenly on both sides of the mouth is generally recommended to prevent strain and promote balanced muscle function.

A. Retropulsion B. Impaired handwriting C. Muscle soreness and pain D. Slow movements

Correct Answer is A

Explanation

A. Retropulsion is a classic manifestation of postural instability in Parkinson's disease. It refers to a tendency to lose balance and fall backward, especially when attempting to initiate walking or when challenged with external forces.
B. Impaired handwriting, also known as micrographia, is associated with bradykinesia (slowness of movement) in Parkinson's disease. It manifests as progressively smaller and more cramped handwriting.

C. Muscle soreness and pain can occur in Parkinson's disease, but they are not typically directly associated with postural instability. They may occur due to rigidity (muscle stiffness) or abnormal postures maintained over time.
D. Slow movements, or bradykinesia, are a hallmark feature of Parkinson's disease and are characterized by a gradual reduction in the speed and fluidity of voluntary movements. While related to motor symptoms in Parkinson's disease, slow movements are not specific to postural instability.
