Answer from: HyperZ

Electrophoresis separates polypeptide chains and DNA chains by their fragment sizes after they have been cut by restriction enzymes are specific sites. Genetic testing involves checking genetic disorders by evaluating DNA sequences or protein amino acid sequences. By using restriction enzymes to cut DNA or polypeptides at specific sites, then run them on an electrophoresis, bands will form that will help indicate whether one has an abnormal sequence at the target site. If so, further analysis is used to determine the sequence by use of next-generation sequencing machines

During genetic testing, a segement of amplified DNA obtained from gene is digested using a restriction enzyme. Electrophoresis allows one to analyze the patterns by separating DNA by size. The process allows separation of different sizes of DNA fragments and provides genetic information in a wide range of data fields. A good example is genetic testing; Human DNA can be analyzed to provide evidence in criminal cases, to diagnose genetic diseases, and to solve partenity cases.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
