Why is it important for dna to condense into chromosomes

Biology
1 answer:
MrRa [10]3 years ago
4 0

Answer:

During mitosis, the condensation of chromosomes takes place which is important for cell in several ways. Each DNA is more than 2 meter long therefore to fit it in the small size of the nucleus and to prevent its tangling cell need to condense the DNA into small units.

Condensation of DNA forms an organized structure in the form of a chromosome that helps in easy separation of chromosome during the time of cell division.

The condensation is also required to form functional genes and to regulate the binding of proteins to these gene thereby regulating the gene activation. Therefore DNA needs to condense into chromosomes.

Helga [31]

Answer:

Conduct an experiment.

Explanation:

Any scientific hypothesis or theory requires the proper step and the procedure to explain the particular points about the theory. Any statement made in the science needs the experimental proof.

The scientific experiments includes the different steps used for the validation of any hypothesis. The experiments can explain the main cause of any phenomena and the factors that might affect the experiments. The experimental studies are performed by the scientists.

Thus, the correct answer is option (e).

umka2103 [35]

Answer:

all the muscles.

Explanation:

The muscular system is composed of all muscles in the body. The main function of the muscles is to produce movement in different parts, voluntary or involuntary, creating equilibrium. Muscles are made of myocytes. There are three types of muscles: smooth muscle,  skeletal muscle, and myocardium.

  • The smooth muscle is formed by fusiform cells, mononucleated, and no transversal striations. There is a protein contraction system, but not as organized as the one of the skeletal muscle.  

Smooth-muscle can be found in organs, vessels, veins, and arteries. It provides sustained contractions, slow and rhythmical, but not voluntary.  

  • Skeletal muscle is the most abundant muscle in vertebrates, constituting the somatic musculature. It proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It is also involved in eye movements, respiration, mastication, deglutition, and phonation. It moves the tongue, the superior esophagus, and the pharynx.  

The skeletal muscle is innervated by axons of the motor neurons coming from the CNS. The contraction of the skeletal muscle is voluntary and fast.  

Cells composing the striated muscle are significantly long and multinucleated. They arrange in bundles, where cells are parallel to each other.  

  • Myocardium tissue is more similar to the striated tissue than to the smooth one. However, there are some differences between them. Cardiac cells are cylindrical and smaller, with ramifications. Cardiac cells only have one nucleus, and occasionally there can be two. Actin and myosin filaments are arranged just as the skeletal ones, and the contraction of cardiac cells is molecularly very similar to the skeletal

According to Darwin's theory of evolution, what causes a struggle for survival in populations? *
goblinko [34]

Answer:

n a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).Explanation:
