How an RNA virus could insert DNA copies into a host's cell? How can it have DNA as an RNA virus? Explain. What is the role of RNA? How does protein synthesis differ between prokaryotes and eukaryotes? Is the difference between RNA and DNA that the RNA duplicates itself in the cytoplas...
How does a DNA virus reproduce its host genome? Why do viruses have both RNA and DNA? How does transfer RNA work? How do viruses with double-stranded RNA type III replicate? How does DNA get turned into RNA? How does a virus move messenger RNA into a cell?
In computer security, a Trojan is a type of malware that can wreak havoc on computer networks. Unlike a virus, which relies on a host program to spread itself, a Trojan relies on unwitting users to let it in.
Unlike a cell, a virus has no way to reproduce by itself. Instead, a biological virus must inject its DNA into a cell. The viral DNA then uses the cell's existing machinery to reproduce itself. In some cases, the cell fills with new viral particles until it bursts, releasing the virus...
This group of cells has the potential to form any of the different types of blood cells and also to reproduce itself. This cell then forms committed stem cells that will form specific types of blood cells. We'll learn more about red blood cells in detail next. Contents Red Blood Cells ...
Viruses are constantly mutating as a means of survival. Like parasites, their goal is to take over host cells and use the host DNA to reproduce. As soon as your immune system learns to block a virus, another version can pop up that may go undetected. This ability means you could get si...
A virus is a piece of code that relies on infecting a program and human activity to spread itself, similar to a biological virus that needs a host to reproduce. Once that program is run, the virus copies itself and sends itself to another computer. A virus can a harmless or harmful. A...
Like allviruses, HIV treads the fine line that separates living things from nonliving things. Viruses lack the chemical machinery that human cells use to support life. So, HIV requires a host cell to stay alive and replicate. To reproduce, the virus creates new virus particles inside a host ...
CRISPR genome editing technology has been inspired by nature itself — the capability of the immune system to kill viruses. The bacteria in the immune system contain “clusters of repeating sequences” in their DNA. When a virus attacks, these bacteria target that virus and cleave its DNA which...
The word virus is often being used as a common term for all malicious programs, but technically a virus is a program or code that attaches itself to a legitimate, executable piece of software, and then reproduces itself when that program is run. Viruses spread by reproducing and inserting th...
