Answer:
The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation
Explanation:
tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.
tRNA then moves to the P site and a new tRNA bind to the A site of ribosome and brings a new amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA recognizes a termination or nonsense codon
The monomers of a DNA have 2'H (Hydrogen) and base is any of the following: adenine, guanine, cytosine or thymine. While in case of RNA, monomers have 2'OH and any of the following bases: adenine, guanine, cytosine or uracil. The presence of 2'OH(Hydroxyl) makes RNA less stable than DNA
Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size.
Both cell types: use ribosomes to synthesize proteins, contain DNA.
Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.
In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.

Answer:
There would be no life (except for viruses [if they are considered to be alive]).
Explanation:
These cells are the "building blocks" of life, and all have RNA or DNA in them and a membrane around the outside. The only example of something "alive" without cells might be viruses (like what causes chickenpox or the flu) which are just packets of protein and DNA.
