The lytic cycle is one of two methods of viral reproduction, the other being the lysogenic cycle. These cycles should not, however, be seen as separate, but rather as some…what interchangeable. The lytic cycle is typically considered the main method of viral replication (reproduction), since it results in the destruction of the infected cell. The lytic cycle is often described in steps, sometimes three steps, sometimes five steps or six steps. But all describe the same process. See the related question below for more information about the steps of the lytic cycle. Penetration To infect a cell, a virus must first enter the cell through the plasma membrane and (if present) the cell wall. Viruses do so by either attaching to a receptor on the cell's surface or by simple mechanical force. The virus then releases its genetic material (either single- or double-stranded DNA or RNA) into the cell. In doing, the cell is infected and can also be targeted by the immune system. Biosynthesis The virus' nucleic acid uses the host cell's machinery to make large amounts of viral components. In the case of DNA viruses, the DNA transcribes itself into messenger RNA (mRNA) molecules that are then used to direct the cell's ribosomes. One of the first polypeptides to be translated is one that destroys the hosts' DNA. In retroviruses (which inject an RNA strand), a unique enzyme called reverse transcriptase transcribes the viral RNA into DNA, which is then transcribed again into mRNA. Maturation and lysis After many copies of viral components are made, they are assembled into complete viruses. The phage then directs production of an enzyme that breaks down the bacteria cell wall and allows fluid to enter. The cell eventually becomes filled with viruses (typically 100-200) and liquid, and bursts, or lyses; thus giving the lytic cycle its name. The new viruses are then free to infect other cells. Lytic cycle without lysis Some viruses escape the host cell without bursting the cell membrane, but rather bud off from it by taking a portion of the membrane with them. Because it otherwise is characteristic of the lytic cycle in other steps, it still belongs to this category. Hepatitis C viruses presumably use this method.
The lytic cycle is one of the cycles of viral reproduction. The phases of the lyric cycle are penetration, biosynthesis, gene regulation biochemistry, maturation and lysis…. In some cases the lysis phase is replaced by the productive phase.

Most of the cell's life is spent in interphase. The cell increases in size, then replicates its DNA. After some additional growth, the cell is ready to divide. Mitotic div…ision occurs and the two daughter cells each return to interphase. Some cells enter senescence and cease to divide.

There are three phases of respiration. The first phase is called pulmonary ventilation. The correct order of the passage of oxygen during the first phase is inhalation of …air into the alveoli or air sacs in the lungs and exhalation of the air. Oxygen diffuses from the alveoli into the blood then the oxygen diffuses from the blood to the cell.

To put these phrases in order a person will need to know what the phrases are. Since they are not provided the answer can not be known.
In Cold and Flu
Lytic refers to lysis which means separate in Greek. When a virus has replicated in a cell, the new viruses made in the cell cause the cell to separate or split open so the vi…rus particles can get out and infect more cells and make more viruses.

This is astonishing! You're looking at a list, and you can't decide which item on the list is the correct one, but you expect me to pick the correct one without even seeing …the list. Any cycle that includes these phrases in this order is correct: . New Moon . Waxing crescent . First Quarter . Waxing gibbous . Full Moon . Waning gibbous . Third quarter . Waning crescent
