Answer:
a. eukaryotes have three different RNA polymerases, whereas prokaryotes only have one RNA polymerase
Explanation:
The initiation represents the beginning of RNA production. Initially, RNA polymerase (transcription catalyzing enzyme) recognizes in DNA the so-called promoter regions. In prokaryotes, there is only one type of RNA polymerase; In eukaryotes, three RNA polymerases are described, and thus the transcription process in this group is more complex.
In the initiation step, we also observe the opening of the DNA strand, a process known as unfolding. This opening occurs because of the rupture between the connections that arise between the bases.
your answer is C- he cell membrane was pressed against the cell wall
Snow is precipitation in the form of ice crystals. It originates in clouds when temperatures are below the freezing point (0 degrees Celsius, or 32 degrees Fahrenheit), when water vapor in the atmosphere condenses directly into ice without going through the liquid stage.
Pollo virus is the virus that matches its structure..The polio virus has a polyhedral shape. The polio virus is considered as the agent that causes poliomyelitis. It is basically a human enterovirus and falls in the family of Picornaviridae
