chromosome test

Expert Solution

Chromosome test is the testing of chromosomes by the preparation of a karyotype. It is also called as karyotyping.

Karyotype is the pictorial representation of chromosomes present in the somatic cell of an individual. It is prepared using a photograph of chromosomes taken at metaphase of mitosis. It is because the chromosomes are maximally condensed at this stage.

Karyotype helps us to determine the number of chromosomes present in the diploid cell of a given individual, shape and structure of chromosomes on the basis of the position of centromere, the sex of the individual and chromosomal abnormalities like deletion, duplication, translocation and inversion.

All the chromosomes on a karyotype are arranged in decreasing order of their lengths with sex chromosome place in the end. Human karyotype contains 46 chromosome out of which two are long and 44 are autosomes.

Given is the image of a karyotype of a normal human male and the one from klinefelter syndrome.

Suppose a translocation occurs between chromosome 14 and chromosome 21 in an individual. A translocation is the result of the fusion between two nonhomologous chromosomes. Chromosome 14 is 109 million base pairs in length, while chromosome 21 is 48 million base pairs in length. For this problem, assume that the translocation fuses the entirety of chromosome 14 to the entirety of chromosome 21. a. How long is the DNA portion of this translocation chromosome in meters? b. How many nucleosomes...

A miscarried fetus has primary Trisomy 16 (3 separate chromosome 16's). The chromosome 16's of the fetus, mother, and father were tested for a common polymorphism involving this chromosome. Four types of polymorphisms commonly occur in the population: A, B, C, and D. The results were: fetus = ABC, mother = AB, father = CD. When and where did the mis-segregation (non-disjunction) event causing trisomy 16 in the fetus most likely occur?
