Answer 1

Explanation:

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat; (3) the occurrence of ether linked lipids built from phytanyl chains

Answer 2

Answer:

Answer :-

First of all, what is Archaebacteria?

Ans - Archaebacteria is a sub-division of the kingdom "Monera".

But, in the six kingdom system of biological classification, for the 1st time, Archaebacteria was given the status of a kingdom.

The two main features of Archaebacteria are as follows :-

The cell wall of Archaebacteria is made up of "*Glycoprotien".

The D.N.A of Archaebacteria contains "Introns" in it.

Extra Information :-

~~~~~~~~~~~~~~~~~~~~~~~~----------------

The presence of "Introns" in the D.N.A. of Archaebacteria is a eukaryotic feature.

3 types of R.N.A. polymerase are present in Archaebacteria.

Ribosomal Protien of Archaebacteria is highly acidic in nature.

Archaebacteria is comparatively more primitive than Eubacteria.

*Note :-

"Glycoprotien" is also known as "Pseudomurin".
