A researcher observes an isolated system containing complex organic molecules undergoing spontaneous self-assembly into membrane-bound structures. These structures exhibit rudimentary metabolism but no reproduction or heritability. Which characteristic of life is the MOST significant barrier preventing these structures from being classified as living organisms?

In which of the following, metabolic reactions take place?

Which of the following processes demonstrates adaptation in living organisms?

The living organisms can be unexceptionally distinguished from the non-living things on the basis of their ability for

Growth in living organism is from

Prions, infectious protein particles, can induce conformational changes in normal proteins, leading to diseases like Creutzfeldt-Jakob disease. While exhibiting self-propagation, prions lack genetic material. Do prions challenge the conventional definition of living organisms, and why?

Imagine a synthetic life form created in a lab that uses a novel information storage molecule distinct from DNA or RNA, but still exhibits heritability and undergoes evolution. Which of the following aspects of the current definition of life would MOST require reconsideration in light of this discovery?

All living organisms show:

The living organisms can be unexceptionally distinguished from the non – living things on the basis of their ability for

Select the correct statement from the following statements

I. Increase in mass and increase in number of individuals are twin characteristics of growth

II. Metabolic reactions can also be demonstrated outside the body in isolated cell-free systems
