They are not able to reproduce independently
They do not use energy for metabolism of any kind
<span>Their virulence is maintained by non-living cultures

Answer:
there are two types of cell one eukaryotic cell that have true nucleus (genetic material enclosed in membrane) and membrane bounded organelles and other is prokaryotic cell that donot have have true nucleus (genetic material dispersed in cytoplasm) and membrane bounded organelles.
similarities between PC and EC is that both contains cell membrane, ribosomes (not a membrane bounded organelle) .
examples of PC are bacteria , paramecium,fungi etc
examples of EC are plant and animal cells
there are two names for cell membrane i.e plasmalemma, cell surface membrane,
selectively permeable or semipermeable means cell only allows those material to pass through its cell membrane which it needs.this cell'ability is important because to protection against the poisonous substance and to maintain cell needs .
As distance between the two objects increases the force of gravity decreases. Hope that helps!
1. The correct answer is: a. There are more mRNA bases than amino acids.
The transcription of monocistronic mRNA in prokaryotes is a rare process (it is more characteristic for the eukaryotes). Monocistronic mRNA is RNA, which encodes for only one or specific protein. Three bases of mRNA encode one amino acid of protein, thus it has more bases than amino acids of the final product, protein.
2. The correct statements are:
The mRNA contains 5' and 3' untranslated regions.
The stop codon does not code for an amino acid.
The start site of transcription is upstream of the start codon.
Each codon contains 3 RNA bases.
All of these approve that more bases are in mRNA since not all of them are translated into amin oacids.
Other statements are hallmarks of eukaryotic RNA processing, and therefore not relevant to prokaryotes.
