Agarose is made from agarose, a polysaccharide from see weeds. Polyacrylamide is made from the synthetic polymerization of acrylamide, which in its monomeric form is a neurotoxin. Based on these structural differences, it could be said that agarose gels have larger 'pores' than polyacrylamide gels meaning that large particles can move more easily in agarose gels since the agarose polymers are larger and pack less densely then an equivalent amount of polyacrylamide. Therefore, agarose is generally used for the electrophoresis of large molecules such as DNA and RNA or speedy separation (low resolution) of small molecules such as proteins. Polyacrylamide is used for the high resolution electrophoresis of small molecules such as proteins.
Agar is a heterogeneous mixture of two classes of polysaccharide: agaropectin and agarose. Although both polysaccharide classes share the same galactose-based backbone, agaropectin is heavily modified with acidic side-groups, such as sulfate and pyruvate. The neutral charge and lower degree of chemical complexity of agarose make it less likely to interact with biomolecules, such as proteins. Gels made from purified agarose have a relatively large pore size, making them useful for size-separation of large molecules, such as proteins or protein complexes >200 kilodaltons, or DNA fragments >100 basepairs.
Agarose is purified from the polysaccharide complex, agar. This purified fraction forms a neutral gel matrix that is commonly used in gel electrophoresis. We have found that for many routine uses, agar which is considerably less expensive than agarose can be used with satisfactory results.
agarose is made of from a type of sea weads.
Yes. Agar is derived from the polysaccharide agarose which comes from seaweed. Agar is a jell. Different types support growth of microbes in the laboratory.
Commercial agar is harvested from the cell walls of the Red Algae- Gelidium amansii. Agarose is a linear polymer that consists of alternating residues of D-galactose and 3,6-anhydro-L-galactose.
ecoli is a lactose metabolizer, can live on macconkey while psuedomoas cannot.
agarose helps in the separation of DNA bands by controlling the pore size of agarose gel
An agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar and used to make gels.

An agaropectin is a heterogeneous mixture of smaller molecules making up the part of agar which is not agarose.
Commercial agar is harvested from the cell walls of the Red Algae- Gelidium amansii. Agarose is a linear polymer that consists of alternating residues of D-galactose and 3,6-anhydro-L-galactose.
A cell wall can be seen in kingdom protista.It may consist of cellulose,silica,agarose,agar,algenic acids

In chocolate agar , blood is lysed by temperature, from that differnt matrials which are helpful to some organisms are release from RBCs.. and from blood agar cells are not lysed and some organisms can not take their nutrients from unlysed RBCs... This is a main difference....
Agar comes from algae. It is used to culture bacteria and can be eaten by humans as a substitute for gelatin.
Zone of inhibition :-It is the area on an agar plate where growth of a control organism is prevented by an antibiotic usually placed on the agar surface. If the test organism is susceptable to the antibiotic, it will not grow where the antibioitic is. Zone of exhibition:-
