According to which theory is the given statement correct?
Statement. B and T cells having receptors for self-antigens undergo programmed cell death
According to which theory is the given statement correct?
The correct option is A Programmed senescence theory
A. Somatic mutation theory - posits that the accumulation of mutations in the genetic material of somatic cells as a function of time results in a decrease in cellular function.
B. Programmed senescence theory - refers to the idea that senescence in humans and other organisms is purposely caused by evolved biological mechanisms in order to obtain an evolutionary advantage.
C. wear and tear theory - asserts that the effects of ageing are caused by progressive damage to cells and body systems over time. Essentially, our bodies "wear out" due to use. Once they wear out, they can no longer function correctly.
D. Immunological theory - asserts that the process of human ageing is, in fact, a mild and generalized form of the prolonged auto-immune phenomenon.
So, the correct option is ‘Programmed senescence theory’.
