Which one of the following statements is wrong with respect to separation of DNA fragments on gel electrophoresis?
4 points
a. Gel electrophoresis is employed to check the progression of a restriction enzyme digestion.
b. The DNA fragments move towards cathode under electric field through the matrix.
c. The smaller DNA fragments moves farther.
d. The commonly used matrix is agarose gel.
Answer:
b. The DNA fragments move towards cathode under electric field through the matrix.
Explanation:
Gel electrophoresis is a molecular biology technique used to separate DNA fragments based on size using electric current. The electric current passes through a GEL (agarose gel is commonly used) matrix. Due to the fact that DNA is negatively charged, they tend to move towards a positively charged electrode called ANODE.
However, the smaller the size of the DNA fragment, the faster and farther it moves along the matrix. Gel electrophoresis is indeed a technique used to check how progressive a restriction enzyme has been able to digest DNA molecule into fragments.

Explanation:
sorry if im wrong but please let me know if this is correct or not
The method of generating electricity that does not use alternative energy resources is burning coal in a power plant.
What are alternative energy resources?Alternative energy resources are eco-friendly resources that can be used to produce energy.
These are renewable resources and can not be extinct.
These resources do not pollute the earth.
Examples are windmills, solar panels, hydropower, etc.
Thus, the correct option is a. Burn coal in a power plant.

How did the crickets lose their ability to chirp?
Answer:
By a mutation that altered the shape of their wings, making them incapable of producing the chirping noise. The feat was achieved over less than 20 generations, a mere evolutionary blink of an eye, and, with the crickets living just a few weeks, a very rapid process.

Glucose is a large molecule that is transported across the cell
membrane through a gated channel, a type of transport protein
used during what
diffusion
The type of transport protein used during glucose transportion across the cell membrane is facilitated diffusion.
Glucose is the main energetic substrate of the cell and requires a transporter protein in the cell membrane for its entry.
Proteins found on the surface of the membrane intervene in facilitated diffusion, which, when they make contact with the molecules, bind to them and allow their entry.
This route is used by molecules that are larger in size, with properties other than the membrane (polar), or are charged and do not cross the membrane freely; for example glucose.
The transport of glucose across the cell membrane is carried out by two families of membrane proteins:
Sodium-coupled glucose transporters are expressed mainly in epithelia that are responsible for the absorption and reabsorption of nutrients.Glucose transporter (GLUT) are expressed in all cells of the body and allow glucose to move from one compartment to another.
Therefore, we can conclude that glucose enters cells through facilitating transport systems, glucose transporter are expressed in all tissues of the organism and transport glucose through its concentration gradient, hence the name of facilitated diffusion.

Oxygen is a product of the electron transport chain.
True or False
Answer:
true
hope this helps you ☺️☺️
Electron transport chain can be defined as the series of organic molecules and proteins which are embedded in the inner membrane of mitochondria. These molecules are involved in the shutting of electrons from FADH2 and NADH to the [tex]O_{2}[/tex].
The molecular oxygen is the final electron acceptor in this electron transport chain that leads to the formation of water and ATP as the end products. This chain takes place in the mitochondria in both animal and plant cells.
Hence, the given statement is true.

Which best represents a balanced equation
Answer:
option C is correct answer of this question
hope it helps
it is balanced equation
The example of a balanced chemical equation is 2H₂ + O₂ → 2H₂O. Thus, the correct option is C.
What is a balanced equation?A chemical equation is the symbolic representation of the chemical reaction in the form of symbols and chemical formulas such as H₂O. Chemical equation are generally are unbalanced however, these reactions can be balanced.
Balancing a chemical equation refers to balancing the stoichiometric coefficients on both the reactants and products side of the reaction which is because the chemical equation must obey the law of conservation of mass of the atoms.
2H₂ + O₂ → 2H₂O
This reaction has 4 H and 2 O atoms.
Therefore, the correct option is C.
