What is a bacterium attacked by T2 and T4 phages?
E-coli
Can virus get a bacteria?
Yes- Bacterial viruses are called bacteriophages. Some examples are T4 and T7 phages. They are complex DNA viruses that attach themselves to the cell surface and then inject their DNA to the inside of the bacteria. Bacteria have enzymes called restriction enzymes that cleave DNA at specific sites called restriction sites. These enzymes are the bacterium's defense against phages.
Surface area of a triangle?
T1= t2= t3= t4= r=
What is the factors of t4-81?
(t - 3)(t + 3)(t2 + 9)
How do you write a algebraic expression using 3.50t?
(e3.50t - t2)/(1 + t4)
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.
What are the factorsof 81?
t4-81 is a difference of 2 squares and can be written as (t2-9)(t2+9) t2+9 can't be further factorised but t2-9 is a difference of 2 squares again and can be factorised to (t+3)(t-3) so the factors of t4-81 are :(t2+9)(t+3)(t-3) Hope this helps :-) I believe the answer you are looking for is (t - 3)(t + 3)(t 2 + 9)
What does compound interest and exponential growth share?
The ratio of the quantity between two sets of time an equal period apart are the same. That is, the rate of growth over the same time is a constant. Suppose V(t) is the value of the variable V at time t. Then, if t1, t2, t3 and t4 are four times such that t2 - t1 = t4 - t3 then V(t2)/V(t1) = V(t4)/V(t3) whether V is compound interest or exponential growth.
What is the instantaneous velocity in s t2-t when t4?
How far will a car travel in 15 min at 20 m/s ?
What does a spacecraft 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"
