1 hours ago Chromosome classification is performed by identifying the morphological features which mainly include the centromere location. The parameter is essential for classification which helps in determining a karyogarm. In this paper, a comparative analysis of two algorithms for identification of centromere position is done.

2 hours ago Automated homologous classification of human chromosomes from the metaphase spread of a cell is an essential task to identify various genetic disorders. Karyotyping is the process of visualizing and categorizing the chromosomes within a cell. It is very important to have a good feature extraction scheme for proper chromosome classification.

6 hours ago In this article we will discuss about the classification of human chromosomes on the basis of size and position of the centromere. All the human chromosomes in nor­mal numbers (46) can be arranged in groups based on size and positions of the centromere. The resulting classification of the chromo­somes is given in the following table:

6 hours ago Three discriminant analysis models for chromo- some classification are developed: one in which each chromosome is classified in isolation, a modification in which the cell, if normal, contains 2 chromosomes of each of the 23 kinds, and a final one in which the cell is the unit of analysis instead of the chromosome. Suggestions are made

2 hours ago Classification of human chromosomes Karyotype is a chromosome set (diploid), located in any of the body's somatic cells. It is characteristic of this organism and is the same in all cells, with the exception of genital cells. Chromosomes in karyotype are: autosomes, do not differ in individuals of different sexes;

9 hours ago Classifier for chromosomes using G-Band chromosome images. G-Band is the most common type of banding. It generates a distinct transverse banding pattern characteristic of each class which is an important feature for chromosome classification and pairing The idea of using G-band images is that, it helps to identify even tiny abnormalities [10].

2 hours ago In a normal human cell there are 46 chromosomes which, at appropriate stages of cell division (prophase and metaphase) can be observed as separate objects using high resolution light microscopy. Figure 18.1 shows chromosomes in a metaphase cell. The chromosomes have been stained to exhibit a series of bands along their lengths.

3 hours ago Chromosome classification. Chromosomes are packaged and organized structures which contain most of the DNA of living organisms. The DNA that constitutes the chromosomes becomes more tightly aligned in the middle of the cell during the metaphase (the cell division) and is then visible on a microscope. In humans, each cell generally contains 23

Frequently Asked Questions

How are chromosomes classified on the basis of size and position?

In this article we will discuss about the classification of human chromosomes on the basis of size and position of the centromere. All the human chromosomes in nor­mal numbers (46) can be arranged in groups based on size and positions of the centromere.

How can chromosome 21 genes be classified by their expression levels?

By use of this new data analysis protocol, human chromosome 21 genes can now be ranked into four classes by their expression levels in DS cell lines relative to controls. This protocol could be applied to expression data obtained from other human tissues, to validate the classification.

How many chromosomes are there in the human body?

All the human chromosomes in nor­mal numbers (46) can be arranged in groups based on size and positions of the centromere. The resulting classification of the chromo­somes is given in the following table:

Should cytologists be able to perform manual chromosome classification?

Cytologists able to perform a manual chromosome classification are rare and the results they obtain could be improved in terms of time, and costs when supported or replaced by machine learning systems.
