Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate the antibiotic has no “target” to attack in a virus however antiviral medications and vaccines are specific for viruses
Answer:
The reason is probably so that each can fit equally well onto the ribosome and carry out its function
Explanation:
The three-dimensional structure or tertiary structure of tRNAs is conserved and crucial for the interaction : it is L-shaped 3D structure that allows them to fit onto the ribosome (its P and A sites). This is important for the function of tRNA: to be link between mRNA (carries the information from DNA) and ribosome (performs protein synthesis-translation).
