A bacterial virus infects the cell by attaching fibers of its protein tail to a specific receptor site on the bacterial cell wall and then injecting the nucleic acid into the host, leaving the empty capsid outside. https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q
The amount and arrangement of the proteins and nucleic acid of viruses determine their size and shape. The nucleic acid and proteins of each class of viruses assemble themselves into a structure called a nucleoprotein, or nucleocapsid. Some viruses have more than one layer of protein surrounding the nucleic acid; still others have a lipoprotein membrane (called an envelope), derived from the membrane of the host cell, that surrounds the nucleocapsid core. Penetrating the membrane are additional proteins that determine the specificity of the virus to host cells. The protein and nucleic acid constituents have properties unique for each class of virus; when assembled, they determine the size and shape of the virus for that specific class. The genomes of Mimiviruses and Pandoraviruses, which are some of the largest known viruses, range from 1 to 2.5 Mb (1 Mb = 1,000,000 base pairs of DNA). http://www.britannica.com/EBchecked/topic/630244/virus/32742/Size-and-shape
The virus gains access to the body, it will make its way to a nearby cell and sit on the lipid membrane of the cell. Once on the cell membrane, the virus will attempt to fit into receptors or keys that will open the cell wall. From there, Discovery Health states the virus injects its own genetic material into the cytoplasm of the cell, leaving the casing of the virus outside of the cell. Viruses contain their own DNA or RNA with codes on how to replicate themselves.
This answers both questions: Yes because viruses go into cells and change the genetic codes from DNA to RNA to create more viruses.. if a virus was bigger it wouldn't be able to get into the cell.
The smallest viruses are smaller than ribosomes in cells, and the largest are so big that they’re just barely visible under the highest power of magnification possible with a regular light microscope. A single virus particle is called a virion, and is made of nucleic acid (either single or double-stranded RNA or DNA depending on what kind of virus it is) in a protein shell. The viral nucleic acid (RNA or DNA) is one molecule (one “chromosome”), consisting of from four to several thousand genes in length. Much current DNA technology research is aimed at inserting “good” genes into otherwise harmless viruses, then letting these infect animals/humans as a way of inserting the needed gene into the host’s cells. The surrounding protein coat that encloses the viral nucleic acid is called a capsid, and its shape, its protein structure, is specific to each kind (“species”?) of virus. An isolated virion is inert: it has no metabolic equipment, thus cannot do any chemical reactions on its own. Virions can be separated into separate nucleic acid and protein components, each separately crystallized and stored, and yet if mixed back together, can reassemble and be just as “viable”, as infective, as before.
yes a virus is smaller then a cell and Infections of permissive cells are usually productive because infectious progeny virus is produced. Most productive infections are called cytocidal (cytolytic) because they kill the host cell. Infections of nonpermissive cells yield no infectious progeny virus and are called abortive. http://www.ncbi.nlm.nih.gov/books/NBK7979/
Yes, a virus is smaller than a cell. "The virus will make its way into the nucleus of the cell and hijack the cell’s replicating and energy process, inserting its own genetic material into the assembly line so more copies of the virus are made rather than a copy of the cell. The process will repeat over and over, producing thousands of copies of the viral material, which make their way into the cytoplasm again." Harvard Medical School

Are viruses alive? Viruses have found an ingenious way of perpetuating themselves, without ever being truly alive. Unlike most living organisms, they can be frozen or boiled, but then explode into life if conditions are right. Viruses enter other organisms' cells and take over their machinery, making copies of themselves, but they can't "reproduce" on their own. http://www.nsf.gov/news/overviews/biology/bio_q01.jsp

The virus is smaller so it can repopulate in the cell to destroy it and if it was big it couldn't go into the cell to kill it.
Yes Viruses are smaller then cells.

It infects the cell then blows it up.
