Explain the fluid mosaic model

Biology
1 answer:
MrRa [10]3 years ago
3 0
The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.

Andrew [12]

Answer:

The correct answer is "For different reasons, including: pathogens developed resistance, people traveling much more frequently and practices of terrorism".

Other is that people are traveling much more frequently than in the past, which helps pathogens from distance places to reach industrialized areas.

Why do we add isopropyl alcohol to the tube of DNA, and what is the result?
Vilka [71]

Answer:

To achieve precipitation of the DNA.

Explanation:

Isopropyl alcohol makes the DNA sediment. The DNA, once out of the solution, becomes visible, as it clumps.

The result of adding isopropyl alcohol is the precipitation or sedimentation of DNA when DNA becomes like a visible thread with the help of alcohol and salt. The precipitation of DNA is important because it removes the dirt from DNA.
