Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.
Answer:
Option (1).
Explanation:
Biological membrane mainly composed of lipids and proteins with the small amount of carbohydrate exposed on the outer surface of the membrane. This membrane plays an important role as it separates the cellular environment and facilitate the transport of the selected molecule.
The flippase enzyme is required to transport the molecules from one side of the membrane to the other membrane. Lipids and proteins can undergo lateral motion but at the different rate within the membrane.
Thus, the correct answer is option (1).
Answer: Option A) receiving; sending
Explanation:
The neuron is made up of many parts, they include:
- dendrites, which are branched and helps in receiving impulses from the adjacent neuron
- axon, a long and extended portion of the neuron that the transmission of impulses along its length away from the cell body.
- synapse etc
Thus, dendrites of neurons is involved in receiving impulses into the neuron, while axons is involved in sending impulses away from the neurons
Answer:
Pressure, P = 28.2 kPa
Explanation:
Given that,
Number of moles, n = 0.54 mol
Volume of ideal gas, V = 35.5 L
Temperature, T = 223 K
We need to find the pressure of ideal gas. The equation of ideal gas is given by :
R is gas constant
P is pressure
So, the pressure of the gas is 28.2 kPa.
