Question

Due to discovery of which of the following in 1980, the evolution was termed as RNA world:

• A. m-RNA, t-RNA-r-RNA synthesise proteins
• B. In some virus RNA is genetic material
• C. RNA has enzymatic property
• D. RNA is not found in all cells

Answer 1

The correct option is C RNA has enzymatic property

Ribozymes are catalytically active RNA molecules.
The first ribozyme was discovered in the early 1980s and led to researchers demonstrating that RNA functions both as a genetic material and as a biological catalyst.
This contributed to the worldwide hypothesis that RNA may have played a crucial role in the evolution of self-replicating systems.
This is referred to as the RNA World Hypothesis.
