what is the lytic cycle and lysogenic cycle?
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.

1: Lytic versus lysogenic cycle: A temperate bacteriophage has both lytic and lysogenic cycles. In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations.

Arguably, lysosomes are vesicles that can store mature lysosomal enzymes and deliver them to a late endosomal compartment when needed. The resulting organelle is called the hybrid organelle or endolysosome. Lysosomes bud off the hybrid organelle in a process referred to as lysosome re-formation (Bright et al. 1997).

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).

Phages that replicate only via the lytic cycle are known as virulent phages while phages that replicate using both lytic and lysogenic cycles are known as temperate phages. In the lysogenic cycle, the phage DNA first integrates into the bacterial chromosome to produce the prophage.

The citric acid cycle (Krebs cycle) is a good example of an amphibolic pathway because it functions in both the degradative (carbohydrate, protein, and fatty acid) and biosynthetic processes. The citric acid cycle occurs on the cytosol of bacteria and within the mitochondria of eukaryotic cells.

In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. ... During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.

What is the main difference between a lytic and lysogenic cycle? In the lytic cycle, the viral genome does not incorporate into the host genome. In the lysogenic cycle, the viral genome incorporates into the host genome and stays there throughout replication until the lytic cycle is triggered.

The Krebs cycle is the second of three stages of cellular respiration, in which glucose, fatty acids and certain amino acids, the so-called fuel molecules, are oxidized (see Figure). The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP.

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.

The lytic cycle is faster, but the lysogenic cycle is more dangerous. Since the word "lysogenic" is longer than "lytic," it is normally the longer and creepier cycle.

In a eukaryotic cell, the cell cycle has two major phases: interphase and mitotic phase. During interphase, the cell grows, performs routine life processes, and prepares to divide.

After infection is complete, the cell dies because the H1N1 virus triggers cell apoptosis. This is to say that the H1N1 virus can be classified as lytic, officially defined as the release of virions through the lysing of the cell to spread the virions.

An active replication of the viral genome results in a lytic infection characterized by the release of new progeny virus particles, often upon the lysis of the host cell. Another mode of virus infection is the latent phase, where the virus is 'quiescent' (a state in which the virus is not replicating).

Recent research suggests that lysosomes are organelles that store hydrolytic enzymes in an inactive state. The system is activated when a lysosome fuses with another particular organelle to form a 'hybrid structure' where the digestive reactions occur under acid (about pH 5.0) conditions.

A lysosome (/ˈlaɪsəˌsoʊm/) is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins, and its lumenal proteins.
