before running the gel, dna is mixed with dye and loaded into _______ by the use of a pipette.
Before running the gel, DNA is mixed with dye and loaded into wells through the use of a pipette.
What is Gel electrophoresis?Gel electrophoresis may be defined as a type of laboratory methodology that is significantly utilized in order to separate mixtures of DNA, RNA, or proteins according to molecular size. This process is used to analyze the biomacromolecules and their fragments on the basis of their charge and size.
In this technique, the molecules that have to be separated are pushed by an electrical field through a gel that contains small pores. Before performing an actual mechanism, DNA is mixed with a dye known as Ethidium bromide and then loaded into wells which are formed by Acrylamide gel through the use of a pipette.
Therefore, before running the gel, DNA is mixed with dye and loaded into wells through the use of a pipette.

. B.9(C) For an enzyme to be able to catalyze a reaction, the active site must---- *
1 point
be occupied by an inhibitor
increase the activation energy level
have a complementary shape to the substrate
cause the enzyme to be destroyed in the reaction
go keilani
A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.
The correct answer is:
Option C. have a complementary shape to the substrate.
This can be explained as:
If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.Activation energy is the minimum amount of energy needed for the reaction.If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.Therefore, the active site should have a complementary shape to the substrate.

two glass tubes are placed in water one of them has very concentrated sucrose solution while the other has a concentrated sucrose solution after an hour what will happen to the liquid levels in the glass
Answer:
The liquid levels in the solution will become more dilute (have more water) due to Osmosis.
Explanation:
This is because Osmosis moves down a concentration gradient so the water outside the solution will become more concentrated and the solution will become more dilute.

separates one cell from another.
Answer:
The cell theory asserts that all cells comes from existing cells
Explanation:
plss mark brainliest
The cell theory asserts that all cells come from existing cells. Option a si correct.
The cell theory is a fundamental principle of biology. It was first proposed in the 19th century by Theodor Schwann and Matthias Schleiden. The cell theory states that:
All living things are made up of cells.Cells are the basic unit of structure and function of all living things.All cells come from existing cells.The cell theory has been supported by many scientific observations and experiments. For example, scientists have observed that cells divide to produce new cells. They have also observed that cells from different organisms have similar structures and functions.
The cell theory is a powerful tool for understanding living things. It allows scientists to study the structure and function of cells, and to understand how cells interact with each other. The cell theory has also led to the development of new technologies, such as cell culture and genetic engineering.
The other options are incorrect. Option b is incorrect because not all cells contain a nucleus. Option c is incorrect because the cell theory was not established in 1665 by Robert Hooke. Option d is incorrect because a cell membrane does not separate one cell from another. A cell membrane surrounds each cell, but it does not separate one cell from another.
