Is a T4 bacteriophage virus living or non living?
Bacteriophage viruses are nonliving. They are DNA or RNA encapsulated in a protein coated capsule with recognition sites to bind to specific target sites on bacteria and insert their genetic material for viral replication or to induce changes in the bacterial genetic material.
What does it mean by a concatemeric molecule?
A concatemeric DNA is the product of multiple replication and recombination. The result of this multiple replication is a molecule which contains many copies of the same DNA connected end-to-end. For example the bacteriophage T4 uses concatemeric DNA for the generation of mature virus particles.
What is the best known bacteriophage and what virus does it attack?
Bacteriophages ARE viruses that attack bacteria, making this question invalid. But if they meant to say "what bacteria does it attack?" then I would say T4 and E. Coli
What is T in T4 bacteriophage?
The T stands for "tadpole."B-cells are named after the first location in which they were observed, the Bursa of Fabricius.
What is a virus that infects E coli bacteria?
T4 Phage
Which viruses inject their DNA?
Bacteriophage T4 virus
What type of disease does the t4 virus cause?
This type of virus is a bacteriophage. It attacks bacteria. The T4 bacteriophage attacks E. coli.
Is a T4 bacteriophage virus living or non living?
Bacteriophage viruses are nonliving. They are DNA or RNA encapsulated in a protein coated capsule with recognition sites to bind to specific target sites on bacteria and insert their genetic material for viral replication or to induce changes in the bacterial genetic material.
Which enzymes do scientists use to bind a new gene to plasmid DNA?
The enzymes to join DNA fragments are called ligases. Two of the most common are: 1) T4 DNA ligase (from bacteriophage T4), this enzyme, a single polypeptide of Mr = 68 kDa, catalyses the formation of a phosphodiester bond between adjacent 3'-OH and 5'-P termini in DNA; and 2) T4 RNA ligase, that catalyzes the covalent joining of 5'-phosphoryl, single stranded DNA or RNA to 3'-hydroxyl, single stranded DNA or RNA. T4 RNA ligase increases the efficiency of blunt-end ligation of double-stranded DNA catalyzed by T4 DNA ligase.
What does T4 indicates in T4 bacteriophage?
the head
Which events occurs in the lytic cycle of bacteriophage T4 infection but not in the lysogenic cycle?
Digestion of host DNA.
What does it mean by a concatemeric molecule?
A concatemeric DNA is the product of multiple replication and recombination. The result of this multiple replication is a molecule which contains many copies of the same DNA connected end-to-end. For example the bacteriophage T4 uses concatemeric DNA for the generation of mature virus particles.
At what point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
What point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
What does a spacecraft virus look like?
Spacecraft virus looks like the Lunar Lander used in the Apollo Missions. Viruses of this type are called phages. The typical "Spacecraft virus" that you see illustrated in textbooks is typically a T4 Bacteriophage, also called "Enterobacteria Phage T4"
A virus that infects a bacterial cell is called?
Bacteriophage is the name given to a virus that infects bacteria. The name is frequently abbreviated to 'phage'. T4 phage is subject to a wide variety of experiments because it infects E. coli, and E. coli is one of the safer, more abundant and best understood bacteria to study.
What is the real name for spacecraft virus?
The spacecraft virus is only named such because the shape of the virus looks like the Lunar Lander used in the Apollo Missions. Viruses of this type are called phages. The typical "Spacecraft virus" that you see illustrated in textbooks is typically a T4 Bacteriophage, also called "Enterobacteria Phage T4"
