What are restriction enzymes and how can they be used to analyze the presence of different alleles?

What are restriction enzymes?

        Restriction enzymes are a protein made by bacteria that cleaves DNA at specific sites among-st  the molecule.

how can they be used to analyze the presence of different alleles?

         Restriction enzymes are used to cut DNA into smaller fragments. The cuts are 99% always made in a specific nucleotide sequences. Different restriction enzymes recognize and cut into many different DNA sequences.

telophase and anaphase

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
