They travel faster towards the negative end of the gel is the best describes smaller DNA fragments that undergo DNA electrophoresis.

What are the characteristics of DNA movement in electrophoresis?

Under the direction of an electric field, electrophoresis divides biomolecules such as proteins, nucleic acids, amino acids, etc. based on their size, shape, chemical charge, etc. A positively charged molecule (Anion) will travel toward the negatively charged electrode (Cation) when the electric field is present. Moving in the direction of the positively charged electrode, or anion, is the negatively charged molecule (cation). "Cataphoresis" is the movement of a positively charged ion toward a negatively charged electrode. Anaphoresis is the term for the migration of a negatively charged ion toward a positively charged electrode.

DNA being negatively charged moves towards positive end of the gel and also smaller fragments are light weighted so move faster that larger fragments that are heavy.

a) The percentage abundance determines how much we have the isotope.

b) The relative atomic mass is 122.5 amu

c) The Rutherford's model explained the atom.

It is clear that the isotope that we know are the atoms of an element that has the same atomic number but they do not have the same mass number. The implication of this is that the elements that are in question have many atoms of the element but they are not exactly alike as we would have expected.

Given that we have the element X we can be able to write that;

Relative atomic mass = Weighted average of all the isotopes

As such we have;

(121 * 0.432) + (123 * 0.531) + (129 * 0.0370)

52.27 + 65.31 + 4.773

Option a is Correct. Specific genes can be active or dormant depending on their surroundings.

The same genes are present in both twins, but not in the same amount of copies. This could explain some minor discrepancies between the twins or why one of them is more susceptible to illness. Similar prenatal conditions (placenta) are shared by identical twins as well, though one may get a little bit more sustenance and care.

A gene is expressed if it is active, and it is not expressed if it is inactive. Inactive genes may become active as a result of environmental influences. Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.

Personality traits are the building elements of personality. So, what exactly is a trait? In a nutshell, it's a generally steady style of thinking and behaving that can be used to characterise someone and compare and contrast them with others.

Traits can be expressed in broad words, such as how well inclined a person is toward other people in general, or in more particular terms, such as how much that person trusts other people. These more distinct components of personality are referred to as "facets" at times. Personality qualities are typically thought to be separate from mental talents (including general intelligence), which are evaluated based on how effectively one reacts to situations or queries.

It is crucial for mitosis to be error free so that the normal and healthy cells do not get transformed to form cancer cells.

Mitosis is basically a cell division in which one cell, the mother cell, divides in order to give rise to two new cells which we call as the daughters cells that are identical genetically to itself. In the cell cycle, mitosis is the process of division in which the DNA splits and forms two equal sets of chromosomes. It is important for both repair as well growth in the body.

It is very important for mitosis to be error free as any fault in the process might result in the transformation of healthy cells into cancer cells which do not have a regulated growth. These transformed cells will keep growing in numbers and give rise to tumors in the body of an individual which might lead to diseases like cancer.

GEL ELECTROPHORESIS

Gel Electrophoresis is a way to sort and measure the DNA strands. Scientists use gel electrophoresis whenever they need to sort DNA strands according to lengths. This technique is also useful for separating other types of molecules, like proteins.

The "gel" is the filter that sorts the DNA strands. It is like a sponge made of gel with many holes in it.  

The DNA samples are placed into holes at one end of the gel.

Electrophoresis is how we push the DNA strands through the gel filter. By adding an electrical current, we can make the DNA move.

Percolation is the process by which water moves from the surface through the soil underground.

This occurs as water moves from regions of higher pressure to regions with lower pressure, such as from the surface downward. The water can be held in the soil and travel in different directions, depending on the soil structure and the rate of movement.

Percolation is the process by which water moves from the surface to deeper layers of soil, through a process of absorption and drainage. This process is driven by the forces of gravity and capillary action, which cause water molecules to move from higher to lower pressure areas. As the water moves through the soil, it is filtered and purified, and can be stored in the soil and used by plants, animals, and other organisms. Additionally, percolation can help to recharge groundwater aquifers, providing a vital source of fresh water for human consumption.
