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.
What else can I help you with?
Viruses do not contradict the idea that all living things are made of cells because?
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.
What characteristics do living things do viruses share?
Pretty much everything.Since viruses are not alive, they have many things in common with that of a non-living things. Some of these characteristics includes:cannot reproduce (viruses need a host in order to reproduce)cannot adapt to the environment (although they change, this is not an environmental adaption)are not made of a cell, nor are they composed of cells. (viruses are much smaller than that of a cell)cannot metabolize (viruses do not eat for energy, nor do they excrete waste material. They only use the energy made by the host cell, or the kinetic energy in gravity, wind, etc.)cannot grow (viruses can only be "assembled" when infecting the host cell.)
What are two things that make viruses hard to fight?
The two things are: 1. Viruses behave as living beings only inside another living cell and act as a non living thing when isolated or outside the living cell. 2. The genetic material of a virus is RNA not DNA which is gives complexity in its study.
Is the outer covering of viruses a capsid made of chitin?
No, the outer covering of viruses is not made of chitin. Viruses have a protein coat called a capsid that surrounds their genetic material. Chitin is a structural polysaccharide found in the exoskeletons of insects and crustaceans.
What are viruses unable to do that all over living things can do?
Unlike living things viruses don't have a metabolism, making them obligatory parasites (they can only reproduce if there's a host cell they can hijack). They also aren't a cell, which is considered by many to be the minimal organisational structure of living things.
What are two types of virisus?
Two types of viruses are DNA viruses, which have genetic material made of DNA, and RNA viruses, which have genetic material made of RNA. DNA viruses typically replicate in the host cell's nucleus, while RNA viruses typically replicate in the host cell's cytoplasm.
What all living things is made of cells?
"All living things are made of cells" would be a biological observation, and it's only true if we disqualify viruses.
What good things to viruses do?
they make you give birth to chickens
What two viruses can impact living things?
polivirus-causes polio and adenovirus-affextss the adenoids
What are two things make viruses different to plants and animals?
1. they don't have cells, virus is a chunk of nucleic acid with a protein coat. 2. most viruses are destructive and they reproduce inside living things.
What are small functioning units that all living things made up of called?
Most living things are made of cells. Viruses are not, but there is some debate about whether they are really alive.
Do all living things have cells?
No, not all living things have cells. While all living things are made up of cells, some organisms like viruses are considered living but do not have cells. Instead, viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat.
Viruses do not contradict the idea that all living things are made of cells because?
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.
What are some names of helpful viruses?
There are no real "Helpful Viruses". Viruses are viruses. They make things go wrong with your computer.
Do viruses reproduce with live or dead?
viruses are nonliving things. but they need living things to reproduces. so live
What two things are used to classify viruses?
Shape,Genetic material,Precense of reverse transcriptase enzyme,Host
What are several things used to classify viruses?
Viruses can be labeled as RNA or DNA viruses and they can be said to have an envelope or to be "naked".
