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.


Are viruses bacterium?

No, viruses are not bacteria. Bacteria are single-celled microorganisms that can reproduce on their own, while viruses are much smaller infectious particles that require a host cell to replicate. Bacteria are considered living organisms, while viruses are often debated as to whether they are living or not.


What does a virus ultimately do to the host cell?

Viruses hijack the host cell's machinery to replicate their own genetic material, produce new virus particles, and eventually cause the host cell to burst, releasing the new viruses to infect other cells. This process ultimately leads to cell death and can cause harm to the larger organism.


What are the two major periods that compose the life cycle of the cell?

The cell cycle can be divided into two major periods: interphase, in which the cell grows and carries on its usual activities; and the mitotic phase, during which the nucleus divides and cytokinesis forms two cells.


Name two reasons that viruses are considered nonliving?

Viruses are considered nonliving because they cannot reproduce independently; they require a host cell to replicate and produce new viral particles. Additionally, viruses do not possess cellular structures or metabolic processes, which are essential characteristics of living organisms.

What are two ways viruses are like living things?

The only characteristic of a living thing that is shared by viruses is genetic material, either DNA or RNA. They do not reproduce, their genetic information hijacks a living cell's machinery, and turns the cell into a virus factory, this is called replication. They do not require food. Some viruses have moving parts that allow them to inject their genetic material into the host cell.


What are two ways that viruses cause infections?

The two ways that viruses cause infection are by lytic infection and lysogenic infection. The virus can enter into a cell, make a copy of itself and the cause the cell to burst in a lytic infection. When a virus embeds its DNA into the DNA of a host cell and replicates, it is a lysogenic infection.


Does a virus reproudce by splitting in two?

No it does not. It reproduces by infecting/controlling a body cell and commands it to produce viruses.


Do Active viruses enter a cell and immediatley begin to multiply?

The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".


Bacteria and viruses do not have a nucleus what helps them reproduce?

Bacteria are prokaryotic type of organisms. They reproduce by binary fission. In place of nucleus, they have a single DNA molecule called nucleoid. Viruses are living only inside a cell. They divide by producing multiple copies of their DNA.


Which describe the activities of a cell that include cellular growth and cell division?

Activities such as DNA replication, protein synthesis, and cell cycle progression are involved in cellular growth and cell division. These processes ensure that the cell increases in size and replicates its DNA before dividing into two daughter cells.


What are the two methods of viruses replication?

The only way viruses can replicate is by parasitizing living cells and using the cell's mechanisms to replicate their genetic materials and protein components.


What are two ways a virus can enter a host cell?

Viruses can cause lytic infections or lysogenic infections. When a virus enters a cell to make copies of itself, causing the cell to rupture, that is called a lytic infection. A lysogenic infection is where a virus incorporates itself into the DNA of the cell it invades and replicates its genetic code.

Before a normal cell becomes too large to carry out normal activities it will divide to form what?

Before a normal cell becomes too large, it will divide through a process called mitosis to form two identical daughter cells. This allows the cell to maintain a proper size and continue carrying out its normal activities efficiently.


What two parts make up all two virus?

All viruses are composed of genetic material (either DNA or RNA) encased in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell membrane.
