Messenger RNA is a molecule that brings amino acids to the ribosome during translation mrna t-rna rrna dna.
It is a molecules which carries the coding sequences for protein synthesis and are called transcripts. Ribosomal RNA (rRNA) molecules molds the core of a cell's ribosomes and move RNA (tRNA) molecules that carry amino acids to the ribosomes throughout protein synthesis.
B. Because virus need the hosts dna to multiply
B - They both use protein channels (I think so at least) they differ because active transports use a pump to leave the cell and it uses atp (cell energy).
Answer:
