What are the two main structures of a virus?
Viruses have a particular character that they need a living host to survive or they cannot otherwise live. Generally viruses have a capsid which has its viral RNA enclosed in it. Capsid is covered by thick membrane.
Both viruses and cells are able to replicate their genetic material What is the main difference in their replication processes?
The main difference is that viruses rely on a host cell's machinery to replicate their genetic material, while cells have their own machinery to replicate their DNA. Viruses insert their genetic material into a host cell and hijack its replication machinery, whereas cells replicate their DNA through processes like DNA polymerase and cellular organelles.
Are there any living things that do not contain DNA as the genetic material?
Yes. Humans cells contain RNA. The most abundant form of RNA in human cells is a type called ribosomal RNA (or rRNA)
How do you xxplain the main purpose of the genetic material in a cell?
the function of genetic material in a cell is to basically give instructions to the cell. the order of the sequence of the bases found in the DNA code for a certain protein to be made at the ribosomes
Is the endoplasmic reticulum related to genetic material?
The endoplasmic reticulum (ER) is not directly related to genetic material. Its main function is to facilitate protein synthesis, processing, and transport within the cell. However, the ER does play a role in lipid synthesis and storage, which are essential for constructing membranes that enclose the genetic material in the nucleus.
What are the two main structures of a virus?

The main functions of nucleic acids are to?
carry genetic material that helps to create structures inside the cell.

What characteristics do scientists use to group viruses?
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
Is genetic material single stranded or double stranded rna?
If the genetic material is RNA, it will usually be single stranded. Only viruses contain double stranded RNA. The main genetic material in eukaryotic cells (eg. animal cells) is DNA. Single stranded RNA copies of this (known as mRNA) are made in order for proteins to be synthesized.
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.
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.
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.
Are there any living things that do not contain DNA as the genetic material?
Yes. Humans cells contain RNA. The most abundant form of RNA in human cells is a type called ribosomal RNA (or rRNA)
What are the main traits of viruses?
They are not alive, they cointain hereditary material inside them, and they are extremely tiny
What are the main differences between a virus and a bacteria which enable scientists to classify them?
Bacteria are single-celled organisms that can replicate themselves. By this, I mean that they have all the genetic material to replicate (DNA & RNA). Viruses, in contrast, contain a piece of genetic material that is encapsulated by a protein coat known as a capsid. Because viruses only have a portion of genetic material, they have to infect a host organism and inject its material into the host and use the host to do the work for the virus. Since bacteria can "live" on its own and viruses cannot, bacterial infections can be treated with medications while viral cannot. In comparison of size, viruses are about 100 times smaller than bacteria. About of 90% of known bacteria live in a symbiotic relationship with humans. This means that the presence of bacteria is beneficial to both the bacteria and humans. In comparison, most viruses feed of the host to produce more viruses... therefore having no benefit to the host.
What are the two parts does every virus have?
Every virus has two main parts: a protein coat called capsid that surrounds and protects the genetic material, and the genetic material itself which can be DNA or RNA. The genetic material contains the instructions needed for the virus to replicate and infect host cells.
