What is it called when a virus attached to host cell injects its nucleic acid into the host cell then makes more viruses?

Attachment, or adsorption, occurs between the virus and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where viral reproduction may begin.

What 2 structures do all viruses have?
All viruses have nucleic acid and a protien coat called a capsid
Paritcle of nucleic acid and protein that can reproduce only by infecting living cells?
These are called viruses.
Does a virus have a protein coat?
Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.
What are the two structures that all viruses have in common?
RNA (Ribo-nucleic Acid) and a Protein coat called the capsid.
vruse are dna and rna?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
What two substances are in a virus?
There are two types of macromolecules in a virus: a protein coat and its own set of viral RNA or sometimes DNA, both contained in its head. It can also have a tail of fibers or phospholipid bilayer to easily attach to the membrane of the host cell.
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
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.
When a phage attaches to a bacterium what does the phage inject and what stays attached to the cell?
The part that remains outside is called the capsid or protein coat.
What are the smaller molcecules that make up nucleic acid called?
The backbone of a nucleic acid is made up of alternating sugar and phosphate molecules bonded together to these are attached the molecule making the rungs of the double helix ladder the Nucleotides.
How did Rosalind Franklin contribute?
Rosalind Franklin had many contributions in the the structural studies of nucleic acids and viruses by X-ray cristallography.
What is an infection in which a virus makes copies of itself and causes the host cell to burst called?
I believe it is called the Ly-tic cycle. The virus attaches itself to a cell and injects DNA. The viral DNA enters the Lytic cycle and new viruses are made. The cell then breaks open and viruses are released. I believe AIDS is such a virus.
