Assertion : Archaebacteria are able to survive in harsh habitats Reason : Presence of peptidoglycan in cell wall help to survive extreme conditions in archaebacteria
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Archaebacteria differs from other bacteria in having a different cell wall structure. This feature is responsible for its survival in extreme conditions. Archaebacteria is characterised by absence of peptidoglycan in the cell wall, it contains protein and non cellulosic polysaccharides.

Which one of the following also acts as a catalyst in a bacterial cell?
1 5S r RNA
2 sn RNA
3 hn RNA
4 23S r RNA
Explanation:
23S r RNA is a component of a large prokaryotic subunit (50S).The ribosomal peptidyl transferase activity resides in this r RNA and acts as a ribozyme(catalytic RNA).
