The cuts on the plasmid are done via restriction enzymes which are also known as molecular scissors. (B) Plasmid 2 is the one that got cut by the restriction enzyme.
<h3>What is the Plasmid?</h3>
A plasmid is a type of double-stranded, circular, tiny DNA molecule that differs from a cell's chromosomal DNA. Both bacterial and certain eukaryotic cells naturally contain plasmids. Plasmids frequently carry genes that give bacteria genetic advantages like antibiotic resistance.
<h3>What is the Restriction enzyme?</h3>
An isolated bacterial protein known as a restriction enzyme cleaves DNA at sequence-specific locations to create DNA fragments with a known sequence at each end. For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
Hence, the cuts on the plasmid are done via restriction enzymes which are also known as molecular scissors. (B) Plasmid 2 is the one that got cut by the restriction enzyme.

Answer:
Explanation:
Length of the ladder, L = 10 ft
dx / dt = 0.9 ft/s
x = 6 ft
Let the angle is θ.
According to the diagram
x = L cosθ
Differentiate both sides with respect to t
At, x = 6 ft
Sin θ = 0.8
So,
0.9 = - 10 x 0.8 x dθ/dt
dθ/dt = - 0.1125 rad/s
The fluid that is being passed through the syringe and needle is incompressible, which means that it will transmit pressure equally. Therefore, the pressure on the plunger will be equivalent to the pressure on the needle. We also know that:
Pressure = Force / Area
Pressure on plunger = 4 / (π*(0.012/2)²)
Pressure on plunger = 35.4 kPa
Pressure on needle = 35.4 kPa
35.4 kPa = F / (4 / (π*(0.0025/2)²)
F = 0.17 N
The force on the needle is 0.17 N
Answer:
Hydrostatic pressure is the pressure exerted by an incompressible fluid (a liquid) at a given point, due to the weight of the fluid above it. Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it.
