how are the lysogenic and lytic cycles different answers?
24514
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.

The major difference is the outer lipid membrane. It's difficult to penetrate, which gives gram-negative bacteria extra protection. Gram-positive bacteria don't have this feature. Because of this difference, gram-negative bacteria are harder to kill.

The first is lytic infection, which occurs when an adenovirus enters human epithelial cells and continues through an entire replication cycle, which results in cytolysis, cytokine production, and induction of host inflammatory response.

In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.

Types of Lysosomes There are two main types, these include: Primary lysosomes - are formed from Golgi apparatus appearing as small vesicles. ... Compared to primary lysosomes, secondary are larger in size and capable of releasing their content (enzymes) outside the cells where they degrade foreign material.

The steps in the lytic replication cycle of an enveloped virus are illustrated for rabies virus, which has a single-stranded RNA genome.

The lytic cycle, which is also commonly referred to as the "reproductive cycle" of the bacteriaphage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.

Which of the following statements best describes the difference between virulent phages and temperate phages? Virulent phages can go through only the lytic cycle, whereas temperate phages can undergo either the lytic cycle or the lysogenic cycle.

The similarities between the lytic and lysogenic cycle are as follows: Both lytic and lysogenic life cycles occur only inside the host cell. ... Both lytic and lysogenic life cycles produce thousands of original virus copies. Both the cycles moderate the protein synthesis and DNA replication of the host cell.

Another key difference is that in the lytic cycle the viruses replicate constantly which results in the eventual lysis, or death, of the host cell to release the new viruses while in the lysogenic cycle the virus replicates only with the regular cellar mechanism for reproduction and is only released through some ...

Following the creation of lysate, the cell debris and proteins are precipitated using a high-concentration salt solution. The high concentration of salt causes the proteins to fall out of solution, and then centrifugation separates the soluble nucleic acid from the cell debris and precipitated protein (1).

Lysogenic Cycle. Once inside the host cell, some viruses, such as herpes and HIV, do not reproduce right away. Instead, they mix their genetic instructions into the host cell's genetic instructions.

A pure culture contains one cell and a mixed culture contains many cells. How can a pure or mixed cutlure become contaminated? ... They become contaminated when another unwanted microbe goes into the medium.

They can develop when lymphocytes (a type of white blood cell that fights infection) grow out of control. CLL has 'leukaemia' in its name because it affects the blood. SLL is another form of the same disease and it mainly affects the lymph nodes (glands), which is why it is called a 'lymphoma'.

What is the difference between a linear and a cyclic metabolic pathway? ... In a linear metabolic pathway, the final product is obtained through a series of a metabolic reaction. On another hand, in a cyclic metabolic pathway, there is a cycle in which starting reactant is produced at the end.

Both require intimate contact between the lytic cell and its target (Fig. 17.1). Although the processes are similar for CTLs and NK cells, CTL lytic activity is acquired only after activation and differentiation, whereas NK cells can spontaneously kill target cells without prestimulation.

Both processes describe the addition of genetic material into cells using various techniques. Transformation is here mostly used for bacterial work (transforming plasmids for example), while transfection is almost exclusively used for eukaryotic cells.
