What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?

Biology
1 answer:
Marizza181 [45]2 years ago
4 0

Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.

<h3>What is crossing over?</h3>

Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.

It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.

It actually occurs at the pachytene stage of prophase I of meiosis cell division.

Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

What is the different between mechanical digestion and chemical digestion in the mouth?
Alborosie

Answer and Explanation:

The mouth is part of the digestion system.

Mechanical Digestion is the physical motion our mouth makes to chew up the food. We grind up the food with our teeth, then swallow the food into the next part of the digestive system.

Chemical Digestion in the mouth is the saliva our mouth produces. It breaks down the food along side the mechanical part of the mechanical digestion.

An immunoglobulin (Ig) molecule, of any class, with regions symbolized as C or V, H or L , has a light chain made up of _______.
Nadusha1986 [10]

An immunoglobulin molecule of any class with regions symbolized as C or V, H or L, has a light chain made up of one C region and one V region.

The glycoproteins known as immunoglobulins (Ig), often known as antibodies, are created by plasma cells. A number of immunogens, including bacterial proteins, promote B cells' conversion to plasma cells. These cells, which make proteins, are involved in humoral immune reactions to bacteria, viruses, fungi, parasites, cellular antigens, chemicals, and synthetic compounds. Using a B-cell receptor, the immunogen or antigen adheres to the B cells' cell surface (BCR).

As a result, a signal is generated that directs the activation of transcription factors, leading to the manufacture of highly specific antibodies for the immunogen that initially activated the B cell. Furthermore, one B cell clone produces immunoglobulin (specificity). Two light chains and two heavy chains that alternate in a light-heavy-heavy-light pattern make up antibodies, also known as immunoglobulins. Therefore, choice A is the right response.

Almost all plant cells have the ability to produce abscisic acid. One of the functions of abscisic acid in plants is to Almost a
kondaur [170]

Answer:

promote stomatal closure during drought stress.

Explanation:

Abscisic acid inhibits the growth and stomatal opening, specifically when the plants are exposed to some stress conditions. Abscisic acid also regulates the seed maturation and seed dormancy. ABA concentration in leaves increases multiple folds under drought conditions. Its accumulation in leaves promotes closure of stomata and prevents the water loss by transpiration. ABA is required to restore the turgor pressure under drought conditions by stimulation of stomatal closure.

AfilCa [17]

Answer:

A point mutation is a type of mutation in DNA or RNA, the cell’s genetic material.

Explanation:

DNA and RNA are made up of many nucleotides. There are five different molecules that can make up nitrogenous bases on nucleotides: cytosine, guanine, adenine, thymine (in DNA) and uracil (in RNA), abbreviated C, G, A, T, and U.
