<span>a mRNA translates a dna to rna and goes to a ribosome
a tRNA reads it and attaches it to a rRNA to make a protein</span>
double stranded molecule does not describe the structure of RNA. Most RNA are single stranded with partial double stranded regions. RNA has basic component as the DNA that is have four nitrogenous base, contain phosphate group and have 5 carbon sugar.
Answer:
The correct answer is Glycocalyx, ribosome and cell wall.
Explanation:
Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.
Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.
Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.
So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
