Why does DNA need to replicate before cells divide?

Answers

Answer 1

Answer:

Below:

Explanation:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Answer 2

whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

What are Vava'u Islands?

Vava's island is a group of islands that contain one large island and 40 smaller islands. They are present in the Tonga region.

They were formed as a result of the subduction of the Australia-India plate beneath the western-moving Pacific plate at the Tonga Trench.

West of the Tonga Trench on the Australia-India plate is the Tongan Islands. When elements in the descending Pacific plate heat up and rise to the surface, volcanoes like this are created.

Therefore, the correct option is a. divergent plates allow magma to come to the surface at this location.

Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.

Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.

are environmental factors more likely to affect genotype or phenotype?

Answers

Environmental factors are more likely to affect phenotype than genotype.

Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.

The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.

Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.

Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.

Answers

The parameters are near complete absorption, high protein binding, and high distribution, extensive metabolization of tamsulosin, and exit of the substance through the urine, as shown in options 1,3,4, and 5.

We can arrive at this answer because:

Oral conjugated equine estrogens are medications taken orally when prescribed by a qualified practitioner.These medications are made with a mixture of several types of estrogens that resemble each other in some way.They are widely used to treat osteoporosis and other common problems in women.

One of the main characteristics and advantages of this type of medicine is that its excesses are eliminated in the urine. In addition, they are easily absorbed by the body, are highly distributed, easily bind to proteins, and are easily metabolized.

HELP NEEDED ASAP! 30 POINTS AND BRAINLYEST TO WHOEVER ANSWERS WITH THE BEST ANSWER! What are 3 examples of gene therapies that are used to treat diseases?

Answers

Answer:

Viruses used in gene therapy are retroviruses, adenoviruses, adeno-associated virus, herpes simplex, and vaccinia. Retroviruses are most commonly used because they can incorporate their genetic material into the host cell’s DNA, thus changing the genetic component of that cell.

Explanation:

Gene therapy is a medical field which focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.
