Is Khagendra Thapa affected by dwarfism?

Yes he is 20 inches tall (1 ft 8 in.) and weighs only 10 lbs at he age of 14. He is affected by dwarfism.Yes he is 1 ft 8 in or 20 in and weighs 4.5 kg or 10 lbs at the age of 14 so he is affected by dwarfism.

Where is a chromosome located inside a cell?

The chromosomes are located inside the nucleus of a eukaryote.

Cell division and chromosome duplication?

Cell division is the process by which a cell divides into two daughter cells. Chromosome duplication occurs during the cell cycle when the DNA is replicated to create identical copies of each chromosome. This ensures that each daughter cell receives a complete set of genetic material.

What are two types of chromosomes in the body how are they different?

the two types of chromatins are euchromatin and heterochromatin.They are different in that heterochromatin is coiled while euchromatin is not coiled.It is this coiling that makes heterochromatin inactive and therefore less in the nucleus when the nucleus is actively involved in protein synthesis.On the other hand,euchromatin is active because its DNA is exposed.

When viewed under a microscope,the two chromatins have different stains.

When do Homologous chromosomes separated?

Homologous chromosomes separate during meiosis I, specifically during the first stage called anaphase I. This separation ensures that each resulting daughter cell receives one copy of each homologous chromosome, contributing to genetic diversity in offspring.

What do chromosomes supply an oganism with?

Chromosomes supply an organism with genetic information in the form of DNA. This genetic information contains instructions for the development, growth, and functioning of the organism. Chromosomes also help in the inheritance of traits from one generation to the next.

What guide or pull chromosomes during mitosis?

The mitotic spindle, comprised of microtubules, guides and pulls chromosomes during mitosis. The spindle fibers attach to the centromeres of sister chromatids and help separate them to opposite poles of the cell during cell division.

What is the protein handle on a chromosome?

The protein handle refers to specific regions on a chromosome where proteins can bind and interact with DNA. These protein handles help regulate various cellular processes such as gene expression, DNA replication, and chromosome structure. They play a crucial role in organizing and controlling the functions of the chromosome.

What is an organism that occurs when a segment of chromosome breaks off and becomes reattached to another chromosome?

Well, the best answer to that is "Mutant".

Not all the mutations of this class are fatal, and in some cases such offsprings are born.

There is a relatively well-known example of such a case in humans- if I'm not mistaken, chromosomes 23 and 9 are involved, where the combination of the two results in a missing stop-codon, leading to a long protein that is disassembled... but I'm afraid I can'trecall the name of the protein or the disease it is related to. probably a cancer of some sort.

To the above person: You may be thinking of down syndrome, that can occur if chromosome 23 has an extra copy (due to nondisjunction).

The process in which a section of DNA is exchanged between homologous chromosomes is known as "crossing-over" and is fairly common. So common, in fact, that it happens in every one of us, and does not mean that we will mutate. All it does is effect the possible combination of traits of our children.

Chromosomes align in center of cell?

During metaphase of mitosis, chromosomes align along the center of the cell (the metaphase plate) to ensure they are evenly separated to opposite poles during anaphase. This alignment is necessary for proper distribution of genetic material to daughter cells.

What are the functions of the long arm of the chromosome?

The long arm of a chromosome carries important genetic information in the form of genes that code for various traits and characteristics. It also plays a role in regulating gene expression, chromosomal structure, and chromosome pairing during cell division. Additionally, the long arm facilitates interactions with other molecules within the cell for proper cell function.

What does a chromosome do in a cell?

Chromosomes contain genetic information in the form of DNA. They play a crucial role in cell division by ensuring that each daughter cell receives a complete set of genetic instructions. Chromosomes also help determine an organism's traits and characteristics.

What are homologous chromosome?

homologous chromosomes are chromosomes that are paired during meiosis. They consists of four chromatids. One pair comes from the father and the other, from the mother.The homologous chromosomes are the same size, their centromeres are in the same postition, they have the same number of genes, arranged in the same order.

the main definition is Chromosomes that have the same length, appearance and copies of genes, although the alleles may differ

What is the chromosome theory of inheritance?

(Was it really necessary to answer eleven times?) Chromosome theory is a principle of genetics. Known as the chromosome theory of inheritance, the principle is that all chromosomes are carriers of genetic material that pass from one generation to the next.

The theory of inheritance was proposed independently by WALTER SUTTON and THEODORE BOVERI

i) Since the sperm and egg cells provides the only bridge from one generation to another, all hereditary characters must be carried in them

ii) The hereditary factors are carried in the nucleus

iii) Like the Mendelian alleles , chromosomes are also found in pairs.

When do chromosomes condense and become thicker rod-like?

Chromosomes condense and become thicker rod-like structures during the prophase stage of cell division, specifically during prophase I of meiosis and prophase of mitosis. This condensation is necessary for the chromosomes to be visible under a microscope and for proper segregation during cell division.

How many centromere is in chromosome?

Chromosomes typically have one centromere, which is a specialized region that holds the sister chromatids together during cell division. The centromere plays a crucial role in ensuring proper segregation of genetic material.

What is the function of a chromosome?

Lemme intellingencify everyall about what the gene is about. It is a heredetary homoglobin extra fuctional funcution that can deduce the mind to all forms of genesifying there is.
Chromosomes are the thread - like structures present in the nucleus that carry genes.Different combination of chromosomes may result in different characters . the chromosome is a organelle that contains little bits and pieces of DNA (genes) and transfers to offspring.

How many chromosomes does a German Shepherd have?

A German Shepherd typically has 78 chromosomes, which are organized into 39 pairs. This is the same chromosome count as most other dog breeds.

What are some of the characteristics governed of the x and y chromosomes?

One of the main characteristics governed by the X and Y chromosomes is determining an individual's biological sex. The presence of the Y chromosome typically leads to the development of male characteristics, while the absence of the Y chromosome usually results in female development. Additionally, X-linked genetic disorders are more commonly observed since males have only one X chromosome.

How was chromosome map developed?

It all began with the mapping of the chromosomes of the fruit fly by Henry Morgan in the early 1900's. Later Dr. Watson (of Watson and Crick fame) at the National Institutes of Health worked on the human karyotype. Many, many people were and still are involved.

Where are chromosomes found?

Chromosomes are found in the nucleus of eukaryotic cells. They are made up of DNA and proteins, which carry the genetic information essential for cell function and heredity. During cell division, chromosomes condense to form visible structures that can be seen under a microscope.

Do genes on the same chromosome separate?

Genes on the same chromosome can separate through a process called genetic recombination or crossing over during meiosis. This process can shuffle genes between homologous chromosomes, creating genetic diversity in offspring.

How many pairs of chromosomes do each human skin cell have?

Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.
