The nucleus is found in eukaryotic cells. The nucleus organizes DNA molecules, along with some protein, to create chromosomes.

Answer: 1. smallpox.
the common cold and different types of flu.
measles, mumps, rubella, chicken pox, and shingles.
hepatitis.
herpes and cold sores. 2. Most notably, viruses differ from living organisms in that they cannot generate ATP. Viruses also do not possess the necessary machinery for translation, as mentioned above. They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. 3. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion. 4.

The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:
1 Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism. 6. Host range is determined by the presence of receptors on the cell's surface. Viruses attach only single species and some attack only particular types of cells within a plant or animal. brainliest?
