Chromosomes

The human cell has 46 chromosomes. In the sex cell of a human it has one half that many. So 23 chromosomes from each parent. Different species have different number of chromosomes. This is why you do not have mixes such as a centaur.

Chromosomes are structures within cells that contain DNA molecules. DNA is the genetic material that contains the instructions for building and functioning of organisms. Each chromosome is made up of a long strand of DNA wrapped around proteins that help organize and compact the DNA.

Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.

A chromosome is an organized structure of DNA and protein that is found in cells. A chromosome is a single piece of DNA that contains many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions

An example of a heterozygous chromosome is having one chromosome with a dominant allele and the other with a recessive allele for a particular gene. This can lead to different traits expressed depending on the dominant or recessive nature of the alleles.

Chromosomes contain DNA, which carries the genetic information that determines an organism's traits. During cell division, chromosomes ensure that each new cell receives the correct amount of genetic material. Chromosomes play a crucial role in passing on hereditary information from one generation to the next.

The chromatin is located in the nucleus of a cell. It contains the genetic material, like Deoxyribonucleic Acid (also known as D.N.A.) Chromatin are tiny little fibers compressed together in the nucleus. It can be likened to a spider's web. To be more exact, the chromatin is in between the nuclear membrane and the nucleosus.

A tomato would happen to have 12 pairs of chromosomes, therefore it has 24 chromosomes. I figured that by multiplying 12 by 2.

A diploid number refers to the number of chromosomes in a cell that exists as pairs (two sets of chromosomes). In humans, the diploid number is 46, with 23 pairs of chromosomes. This number is characteristic of somatic cells and is double the haploid number found in gametes.

it is made up of PROTEINS and DNA MOLECULE, it is located in the nucleus.

They look the same as animal chromosomes. The individual chromatids are worm-like in appearance and are normally joined in pairs at the centre (the centromere); simplistically they look like two parallel lines joined by a dot in the centre. The number of chromosomes in a nucleus varies from plant species to plant species.

The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.

To determine if a child has an extra half of a chromosome, genetic testing such as a chromosomal microarray analysis or a karyotype test would be needed. These tests can identify any abnormalities in the number or structure of chromosomes in an individual's cells. It is important to consult with a healthcare professional or a genetic counselor for proper diagnosis and guidance.

There is no change in chromosome number. Just in the amount of chromatids. Because during synthesis each chromosome doubles and becomes sister chromatids.

yes there are because in a goldfish body cell there are 94 chromosomes. in order to find the amount of chromosomes in a sex cell of a goldfish you need to divide the body cells by two. this is so because in order to make another goldfish half need to come from daddy and half need to come from mommy this is why you divide by half. therefore there are 47 chromosomes in a goldfish's sex cell.

it depends...

If the cell is somatic (non-sex cell) the daughter cells each have 46 chromosomes (in humans, this is.) The daughter cells are diploids.

If the cell is a germ cell (sex cell), the daughter cells each have 23 chromosomes (in humans). The daughter cells are haploids.

Chromosomes come in pairs as a result of sexual reproduction. In humans, one set of 23 chromosomes comes from your mother and one set of 23 comes from your father. When the sperm fertilizes the egg, the two sets of chromosomes come together to make the zygote, which has two sets of 23 chromosomes, for a total of 46. All the body cells of a human have the same number of chromosomes, which is 46.

Studies have shown that certain genetic variants located on chromosomes 2, 8, and 15 may be associated with an increased risk of developing glaucoma. However, glaucoma is a complex disease with multiple genetic and environmental factors influencing its development.

The X chromosome is the female chromosome. In humans, the 23rd pair of chromosomes are the sex chromosomes. If both chromosomes are X, then the person is female, generally speaking. If there is a Y chromosome and an X, then the person is male.

The DNA of a cell condenses to form chromosomes during cell division or mitotis, called the M phase of the cell cycle. Specifically, chromosomes acquire their characteristic X shape in the metaphase stage of mitotis. Each chromosome consists of two sister chromatids joined at the centromere.

Chromosomes contain DNA that carries genetic information essential for traits and functions of an organism. During cell division, chromosomes ensure that genetic material is correctly copied and distributed to offspring cells. Chromosomes play a crucial role in determining characteristics, such as eye color, height, and susceptibility to diseases.

The 24 in chromosome 8q24 denotes the specific location of a gene on chromosome 8. Chromosomes are numbered from 1 to 22 based on size, with 23 being the sex chromosomes. The q indicates the long arm of the chromosome, and the 24 specifies the banding pattern within that region.

In human skin cells produced by mitosis, there are 46 pairs of chromosomes, totaling 92 individual chromosomes. This is because each pair consists of one chromosome from the mother and one from the father.

Researchers at Texas Scottish Rite Hospital for Children (TSRHC), one of the nation's leading pediatric centers for research and the treatment of orthopaedic conditions, have identified the first gene -- CHD7 -- associated with idiopathic scoliosis (I.S.), the most common spinal deformity in children. With no known cause or cure, idiopathic scoliosis poses a significant health burden to the pediatric population. The condition affects approximately two to three percent of school age children in the U.S. and costs an estimated several billion dollars in surgical treatment each year. The medical breakthrough is a result of a 10-year study conducted at the Sarah M. and Charles E. Seay/Martha and Pat Beard Center for Excellence in Spine Research at Texas Scottish Rite Hospital for Children, led by Carol Wise, Ph.D. With the goal of identifying genes causing idiopathic scoliosis, the research team conducted genome-wide scans and follow-up studies of 53 large families, totaling 130 individuals with a confirmed I.S. diagnosis. As a result, the team identified the first gene associated with I.S., allowing the medical community to form hypotheses to explain what causes the condition, and providing tools for future studies. "This is the most definitive link between genetics and scoliosis that has been reported so far," said Dr. Wise, director of molecular genetics at Texas Scottish Rite Hospital for Children. "It has been known for many decades that scoliosis tends to be inherited within families, but now we have found a gene which is clearly related to the development of scoliosis." Most often seen in otherwise healthy children, I.S. is an S-shaped curvature of the spine as viewed from the front that develops as the child grows. Onset typically occurs during the period of rapid growth at adolescence, and children who are still growing, particularly girls, are at the greatest risk for developing severe disease. A long-known condition, I.S. was described by the ancient Greeks and affects all populations worldwide. "This discovery lays the groundwork for future research that will hopefully identify the specific abnormalities which cause the spine curvature," said Dr. Tony Herring, chief of staff at Texas Scottish Rite Hospital for Children. "When we understand these mechanisms, we may be able to develop new preventative measures and better treatment methods." With expert researchers, biomedical engineers, physicians, staff and patients all under the same roof, Texas Scottish Rite Hospital for Children has a record of interdepartmental cooperation that generates an exceptional number of patents, discoveries and improved treatments for patients. The hospital's prestigious research efforts and innovative treatment methods make it a leader in spine research and have allowed the hospital and its staff to significantly improve care of young patients with spinal deformities throughout Texas, the United States and the world. Texas Scottish Rite Hospital for Children is one of the nation's leading pediatric centers for the treatment of orthopedic conditions, certain related neurological disorders and learning disorders, such as dyslexia. There is no charge to patient families for treatment at the hospital, and admission is open to Texas children from birth to 18 years of age. This research was funded through generous contributions from: Fondation Yves Cotrel pour la Recherche en Pathologie Rachidienne de l'Institut de France and the Scoliosis Research Society. The hospital's work is also made possible through the establishment of the Pediatric Molecular Genetics Research Laboratory at Texas Scottish Rite Hospital for Children, which was funded by: The Crystal Charity Ball 1997; Beneke Companies; Horace C.
