Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.
DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel

Transporting substances in a cell. proteins are transported either in or out of the cell.
Answer:
Explanation:
The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.
These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.
WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:
==＞ If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.
==＞build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.
==＞ absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.
==＞ Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.
