Summary Introduction

Introduction:

Peptidoglycan is also termed as murein. It is a polymer of amino acids and sugars and forms the cell wall of bacterial cells. The sugar part of peptidoglycan has alternate units of β-linked N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG).

Expert Solution & Answer

Answer to Problem 1FIB

Correct answer:

Bacteria have peptidoglycan in their cell wall, but archaea do not.

Explanation of Solution

Bacterial cells have cell wall made up of peptidoglycan. Archaea are not closely related to bacteria. Archaea is a domain that consists of single-celled prokaryotic microbes. They have circular chromosomes and their transcription and translation are similar to eukaryotes. No membrane-bound cell organelles are present. Archaea have cell wall, but not composed of peptidoglycan. It is made up of pseudo peptidoglycans or ether-linked lipids.

Conclusion

Cell wall of archaea is not made up of peptidoglycan and they are not closely related to bacteria.
