How do specialized transduction differ from regular Lysogeny?
How do specialized transduction differ from regular Lysogeny?
How does specialized transduction differ from regular lysogeny? The prophage in specialized transduction carries with it pieces of the host chromosomal DNA. During lysogeny, the viral genome integrates into the host DNA, becoming a physical part of the chromosome.
What happens to the packaged DNA of a specialized transduced phage when it infects a new recipient cell what happens to the packaged DNA of a specialized transduced phage when it infects a new recipient cell the DNA is chewed up by enzymes found in the recipient cell the host DNA integrates with the prophage into?
The prophage in specialized transduction carries with it pieces of the host chromosomal DNA. What happens to the packaged DNA of a specialized transduced phage when it infects a new recipient cell? The host DNA integrates, with the prophage, into the new recipient chromosome.
How are prions different from all other non infectious agents?
How are prions different from other infectious agents? They lack nucleic acid. The normal function of the PrP protein in mammals is believed to be: assisting in normal synaptic development and function.
What is the function of the structural elements of a virus What is the function of the structural elements of a virus?
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
What are the 4 shapes of viruses?
Viruses come in many shapes and sizes, but these are consistent and distinct for each viral family. In general, the shapes of viruses are classified into four groups: filamentous, isometric (or icosahedral), enveloped, and head and tail.
What parts do all viruses have?
All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.
Is Covid-19 single stranded RNA virus?
Coronaviruses (CoVs) are a highly diverse family of enveloped positive-sense single-stranded RNA viruses. They infect humans, other mammals and avian species, including livestock and companion animals, and are therefore not only a challenge for public health but also a veterinary and economic concern.
Is influenza single or double stranded?
All influenza viruses consist of single-stranded RNA as opposed to dual-stranded DNA. The RNA genes of influenza viruses are made up of chains of nucleotides that are bonded together and coded by the letters A, C, G and U, which stand for adenine, cytosine, guanine, and uracil, respectively.
