The main difference between the lysogenic and lytic cycles is the outcome of the bacteria. In the lysogenic cycle, the bacteria is preserved and replicates normally. In the lytic cycle, the bacteria is broken apart and destroyed through a chemical process known as lysis.Continue Reading
The lysogenic and lytic cycles are the two life cycles used for replication by a specific group of viruses known as bacteriophages. Bacteriophages are viruses that target and infect only bacteria and can be either temperate or virulent, which are nonlethal and lethal respectively to the bacterial hosts. Temperate viruses follow the lysogenic cycle for reproduction, while virulent cycles follow the lytic cycle.
In the lytic cycle, the bacteriophage injects its viral DNA or RNA particle into the bacterium. The viral particle can attach to a bacterial chromosome and become a prophage, or it can proceed directly to lysis. Either way, the next step in the cycle involves the viral particle replicating at a fast rate until the bacterium's resources are used up and the cell is lysed. The lysogenic cycle begins similarly, with the bacteriophage infecting the bacterium and the viral particles attaching to the bacterial chromosome. Instead of lysing the cell, though, the viral particles replicate as the bacteria replicates through mitosis. Although the lysogenic cycle itself is nonlethal, a lysogenic bacterium may enter the lytic cycle and lyse.Learn more about Biology
An incomplete dominance Punnett square is a diagram that predicts the outcome of genotype as well as phenotype in organisms. With incomplete dominance, the dominant allele in a heterozygote is only partially expressed, which results in an intermediate phenotype.Full Answer >
The soybean plant experiences two main growing cycles: the vegetative stages, which include emergence, the unfolding of the unifoliolate leaves and a series of appearance of trifoliolate leaves; and the reproductive states, which include flowering, the appearance of pods, increasing levels of seed growth, and full color maturation. Specific details of each growing stage depend on the variety of soybean plant cultivated.Full Answer >
Citrobacter freundii appear as Gram-negative, rod-shaped bacteria that are 0.3-1 micrometer in diameter and 0.6-6 micrometers in length. Citrobacter have hair-like extensions, called flagella, that are distributed all over the surface of the bacteria, enabling movement, as stated by the Public Health Agency of Canada.Full Answer >
Spirilla bacteria are Gram-negative bacteria that may cause bacterial diarrhea, adenocarcinoma and peptic ulcers.These bacteria are one of several varieties of bacteria that cause illness or disease in humans; mycoplasmas, chlamydiae, spirochetes and mycobacteria are other virulent and potentially destructive organisms. Spirilla bacteria are identified by their unique body shapes, which resemble spiral pasta noodles, and the type of physical harm that they cause to humans.Full Answer >
