What is membrane gelling?
Membrane gelling refers to the process where a liquid or sol forms a gel-like structure when it comes into contact with a membrane. This can be used in various applications such as filtration, separation processes, and drug delivery systems. The membrane provides a supportive matrix for the gel formation.
What are the differences between stacking gel and resolving gel in gel electrophoresis?
In gel electrophoresis, the stacking gel is used to concentrate and separate the samples before they enter the resolving gel. The resolving gel then separates the samples based on their size and charge. The stacking gel has a lower concentration of acrylamide, allowing for faster movement of the samples, while the resolving gel has a higher concentration for better separation.
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
What is the purpose of the gel used in gel electrophoresis?
The purpose of the gel used in gel electrophoresis is to separate and analyze DNA fragments based on their size. The gel acts as a sieve, allowing smaller fragments to move faster through the gel than larger fragments, resulting in distinct bands that can be visualized and studied.
What is the gel used for in gel electrophoresis?
The gel used in gel electrophoresis is a porous material that helps separate DNA, RNA, or proteins based on their size and charge when an electric current is applied.
What are the advantages of sol-gel process?
Key advantages offerred by the sol gel process 1.it uses relatively low temperature 2.it can create very fine powder 3.it produces compositions not possible by solid-state fusion

What is the changing of the sol and gel phases of the cytoplasmic matrix can result in organelle movement called?
The changing of the sol and gel phases of the cytoplasmic matrix that results in organelle movement is called cytoplasmic streaming. This process involves the reversible conversion of the cytoplasm from a more fluid-like sol phase to a more gel-like phase, allowing organelles to move along with the flowing cytoplasm.
What exhibits the sol gel phenomenon?
The sol-gel phenomenon is commonly exhibited in the formation of colloidal sols and gels from a solution where a network of solid particles forms within a liquid medium. This process involves the conversion of a sol (dispersed phase) into a gel (continuous phase) through controlled chemical reactions or physical processes, resulting in the formation of a solid material with unique properties. Examples include silica gels, metal oxide gels, and polymer gels.
What is protoplast and spheroplast?
a protoplast is aliving substance of the cell. it has the same consistency with that of the egg and is a colloidal substance with a sol-gel manner.

How amoeba locomote by sol-gel theory?
hi friends this may help you,Sol - gel theory is proposed by hyman . It helps some protozoans to move. it is basically consists of some steps which are as follows:-1) The cytoplasm inside the cell is capable of changing into different forms i.e. from fluid to solid and vice versa. When the cytoplasm is in fluid state, it is known as plasma sol, and the more solid or gel like state is called the plasma-gel.2)The interchange of plasma sol to plasmagel is known as Sol-Gel theory and is responsible for amoeba movement.3) When the cytoplasm is in solid or gel like state, there is no locomotion. Movement takes place only when the cytoplasm is in fluid state. This way the amoeba "drags" itself and this movement is known as amoebic movement.4)The locomotion in the amoeba is effected by the formation of temporary finger-like processes of pseudopodia (false-feet, greek, pseudos, false + podos, foot).5)The plasma-sol changes into rigid plasmagel (gelates) at the anterior end and at the posterior end the plasma-gel changes into plasmasol (solates) causing a forward streaming of the more fluid plasma-sol.6)That is why in actively progressing specimens the plasma-sol is continuously rapidly streaming forward, while the plasma-gel is practically everywhere at rest forming, so to say, a tube within which the plasma-sol flows.7)It the course or a granule or crystal fairly straight course either until it reaches or nearly reaches the inner surface of the plasma-gel at the tip of an advancing pseudopod, then it deflects to the right or to the left, upward or downward and sooner or late, directly or indirectly comes into contact with plasma-gel into which it finally changes.8)Other granules are similarly coming and changing it to plasma-gel after attaching to it behind the crystal under observation. As more of these are coming in the same way the position of the first recedes from the anterior and approaches the posterior end of the amoeba. When it reaches this end it gradually moves inward and enters in the plasma-sol, after which it moves forward and the whole processes is again repeated.9)This gives an idea about the movement of the plasmasol and plasmagel. From this, the phenomenon of locomotion can be easily deducted.****************************KEVIN (Jr M.P.L) KAKINADA A.P*************************
What is difference between sol and gel and emulsion?
Sol state is a liquid state .The colloidal particles repel each other. Gel state is more jellylike. The colloidal particles attract each other. emulsion are colloidal system in which both dispersed phase and dispersed medium are in liquid state .

What are the three types of colloidal system?
The three types of colloidal systems are sol, gel, and emulsion. In a sol, solid particles are dispersed in a liquid; in a gel, a network of solid particles is formed within a liquid; and in an emulsion, two immiscible liquids are dispersed in each other with the help of an emulsifying agent.
