What else can I help you with?
Do the cells of hyphae often contain more than one nucleus?
Yes, some do. Filamentous fungi (PHYCOMYCETES) may contain multiple nuclei in a coenocytic mycelium.
What are the phages called that are capable of using both modes of reproduction?
Phages that are capable of using both the lytic and lysogenic modes of reproduction are called temperate phages. In the lysogenic mode, temperate phages integrate their DNA into the host genome, while in the lytic mode, they replicate and cause cell lysis.
What type of cell is a spirogyra?
Spirogyra is a filamentous green alga composed of elongated cylindrical cells. These cells are eukaryotic and contain chloroplasts capable of photosynthesis.
Why are lysogens immune to superinfections?
Lysogens are immune to superinfections because they already contain a prophage (viral DNA) integrated into their bacterial genome. This prophage confers immunity by blocking the entry of new phages or preventing their replication inside the host cell. This phenomenon is known as superinfection immunity.
What cyanobacteria contains a sheath?
Cyanobacteria in the genus Oscillatoria is known to contain a sheath. The sheath is a protective covering that surrounds the filamentous cells of Oscillatoria, providing structural support and protection.
What is a virulent phages?
phages of virulent.
When was Phages - EP - created?
Phages - EP - was created in 2006.
Can two phages infect bacteria at a time?
It can be.in this way we can obtain new phages thah share genes of bpth phages.
What do you call a bacteriophage when it is in a lysogenic cycle?
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.
Do the cells of hyphae often contain more than one nucleus?
Yes, some do. Filamentous fungi (PHYCOMYCETES) may contain multiple nuclei in a coenocytic mycelium.
What are the phages called that are capable of using both modes of reproduction?

Organisms that are unicellular colonial filamentous and photosynthetic is?
Unicellular,filamentous and photosynthetic organisms are ALGAE
How virtulent phages can multiply?
Virulent (virtulent) phages multiply by first attaching itself to a host cell and then absorbing it. Next, it injects its own DNA and the host eventually bursts and more phages present.
What type of cell is a spirogyra?
Spirogyra is a filamentous green alga composed of elongated cylindrical cells. These cells are eukaryotic and contain chloroplasts capable of photosynthesis.
What is the genetic material of a bacteriophage?
1. Size - T4 is among the largest phages; it is approximately 200 nm long and 80-100 nm wide. Other phages are smaller. Most phages range in size from 24-200 nm in length.2. Head or Capsid - All phages contain a head structure which can vary in size and shape. Some are icosahedral (20 sides) others are filamentous. The head or capsid is composed of many copies of one or more different proteins. Inside the head is found the nucleic acid. The head acts as the protective covering for the nucleic acid.3. Tail - Many but not all phages have tails attached to the phage head. The tail is a hollow tube through which the nucleic acid passes during infection. The size of the tail can vary and some phages do not even have a tail structure. In the more complex phages like T4 the tail is surrounded by a contractile sheath which contracts during infection of the bacterium. At the end of the tail the more complex phages like T4 have a base plate and one or more tail fibers attached to it. The base plate and tail fibers are involved in the binding of the phage to the bacterial cell. Not all phages have base plates and tail fibers. In these instances other structures are involved in binding of the phage particle to the bacterium.
Why are lysogens immune to superinfections?
Lysogens are immune to superinfections because they already contain a prophage (viral DNA) integrated into their bacterial genome. This prophage confers immunity by blocking the entry of new phages or preventing their replication inside the host cell. This phenomenon is known as superinfection immunity.
A bacterium attacked by T2 and T4 phages?
