Answer:
bacteria; regulatory proteins
Step-by-step explanation:
Archea are microorganisms (e.g bacteria). They are prokaryotic in nature and they are single celled. They do not have a well defined nucleus.
Archea carry out various metabolic and chemical processes. They also try to minimize the level of stress.
Archea uses regulatory proteins such as RNA polymerase to carry out transcriptional control on the various metabolic and chemical processes that are involved in.
The transcriptional control process is simulate to that of bacteria.
The transcriptional control process occurs in 3 steps.
a. Initiation
b. Elongation
c. Termination
