What three main structures do all viruses have?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA.Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.The naked viruses are more resistant to changes in the environment.A virus can have one of three structures. These are:Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus.Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.Polyhedral virus.
True or False The central core of an atom is called a HUB?
I'm not really sure if it's called a HUB, but I do know that the central core of an atom is called the nucleus, and is made out of protons (with a positive charge) and neutrons (with no charge).
Why do scientist have difficulty including viruses in the catogory of living thing organisims?
Because a virus is not a living cell. It consists of an outer coat of protein surrounding a core of DNA or RNA. A virus can reproduce while it is inside a living host cell, but outside the host organism, it shows no sign of life. As such, viruses are not included in any of the six kingdoms of living things.
Layer of the Earth made mostly of iron.?
Inner core, which is also the innermost region of the Earth.
The region in which earth's magnetic field is found is called the?
The magnetosphere, most specifically the Ionosphere.
What is a biological particle composed of a nucleic acid core and a protein cover called?
If it consists only of these two components it is a virus.
The nucleic acid core of a virus contains?
ribose
What a biological particle composed of a nucleic acid core and a protein cover is called a?
Virus (singular-virion)
What part of the HIV virus serves to protect the nucleic acid core?
viral load
What is a caspid'?
The protein coat or shell of a virus particle, surrounding the nucleic acid or nucleoprotein core
What is the Nucleic acid core definition?
a core is The part of a nuclear reactor where binary fission occurs.Some viruses contain DNA (deoxyribonucleic acid)and other viruses contain RNA (ribonucleic acid). Either of these molecules is responsible for the primary qualities of life that viruses display while inside host cells. The nucleic acids are genetic instructions for viral activity and reproduction.
How is the viral nucleic acid core different from the nucleicid of the bacterial host?
The viral nucleic acid core is composed of the genetic material specific to the virus and is often surrounded by a protein coat. In contrast, the nucleic acid of the bacterial host is the genetic material of the host bacterium and is usually localized within the bacterial cell. Additionally, bacterial nucleic acid is typically organized within a nucleoid region in the bacterial cytoplasm.
What is the function of the nucleic acid within a virus?
The nucleic acids (RNA and DNA) are enclosed in a protein coat called a capsid. Viruses are divided into two groups for classification: those with RNA and those with DNA. Viruses do not duplicate themselves outside of a cell. They are able to replicate only within cells. The DNA or RNA is able to direct the cells to make more viruses.
What are the 2 main components of a virus?
All viruses have 2 basic parts: a protein coat that protects the virus and an inner core made of genetic material.
If you opened a virus what would you?
You would find nucleic acids and core proteins
The genetic material of a virus is found in its .?
The genetic material of a virus is found in the capsid.
What are 4 main parts of a virus?
A virus typically consists of genetic material (DNA or RNA), a protein coat called a capsid that encloses the genetic material, an envelope derived from the host cell membrane (in some viruses), and sometimes additional structures like spikes or tails for attachment and entry into host cells.
