Did you know?
WebDNA in eukaryotes is found in the chromosomes located in the nucleus of the cell. When you look more closely at a chromosome, you can see that it is made up of a long, coiled strand of DNA that is wrapped around proteins called histones. This coiling allows the DNA to be compacted and fit into the nucleus. The coiled DNA and histones together ... WebA virus is an infectious particle that reproduces by "commandeering" a host cell and using its machinery to make more viruses. A virus is made up of a DNA or RNA genome inside a protein shell called a capsid. Some viruses have an external membrane envelope. Viruses are very diverse.
