DNA virus has DNA genetic material while a RNA virus has RNA genetic material. Both of these different types of viruses have different ways affecting the host cell. When DNA viruses enter the host cell, it travels to the nucleus in order to take over the cell’s genetic material. Once the DNA virus has reached their goal they start replicating their DNA and turning it into RNA. On the other hand, when a RNA virus enters a host cell, they have to convert their RNA to DNA. After this step is finished, it allows the virus to inject its genetic material into the host cell, which is a similar process to the DNA

A ribosome is composed of one large and one small subunit that assemble around the mRNA. The mRNA now passes through the ribosome. Now, amino acid building blocks are carried into the ribosome attached to specific transfer RNA (tRNA) molecules. The small subunit of the ribosome arranges the mRNA so that it can be read it segments of 3 nucleotides.
