B)RNA ploymerase reaches a terminator region.
C)Nucleotides are covalently linked together.
D) RNA polymerase binds to a promoter region of DNA.
Bacteria and archaea differ in their cell walls makeup.
Further Explanation:
Archaea is considered to arise many years ago and is also considered to be the most primitive form of life. Earlier they were classified as bacteria but as they possessed certain difference features when compared with bacteria, it was now termed as archaea. Some of the characteristics of archaea resembles eukaryotes while other resembles with prokaryotes.
Archaea are single celled organism and they can thrive in harsh conditions like marshy area and hot springs. Some of the example of archaea are, Thermococcus litoralis, Methanopyrus kandleri, Cenarchaeum symbiosum etc.
The features of archaea which are similar to bacteria are:
1. Lack of nuclear envelop.
2. Lack of membrane bound envelop.
3. Presence of circular chromosomes.
The features of archaea which are similar to eukaryotes are:
1. Methionine is the initiator amino acid for protein synthesis.
2. Lack of peptidoglycan in their cell wall.
3. Association of histones with DNA.
