Assertion: Coaccrvates are believed to be the precursors of life.

Reason: Coaccrvates were self-duplicating aggregates of proteins surrounded by lipid molecules

  • If both Assertion and Reason are true and Reason is the correct explanation of Assertion

  • If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

  • If Assertion is true but Reason is false

  • If both Assertion and Reason are false.

Solution

C.

If Assertion is true but Reason is false

A coacervate is a spherical aggregation of lipid molecules making up a colliodal inclusion which is held together by hydrophobic forces. Coacervates measure 1 to 100 micrometers across, possess osmotic properties , and form spontaneously from certain weak organic solutions. Their name derives from the Latin coacervare, meaning to assemble together or cluster. It was suggested by Oparin that coacervates may have played a significant role in the evolution of cells.
