On the other hand it has been shown that chromosomal DNA may consist of a series of segments of replicons. A symmetric karyotype is a karyotype which shows a smaller difference between the smallest and largest chromosomes in the set. And, they have median or sub-median centromeres. Chromosomes divide into 22 numbered pairs (autosomes) and one pair of sex chromosomes (X and Y). DNA: DNA stands for "deoxyribose nucleic acid.". A symmetric karyotype has more metacentric chromosomes while an asymmetric karyotype has more acrocentric chromosomes. Sometimes you can inherit the genetic mutation from a parent and sometimes the gene mutates randomly mutates in you, with no history of the mutated gene or the genetic condition in your family.

DNA of a particular cistron transcribes its m-RNA by their specific anticodons. View the full answer. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics. It has a fewer metacentric chromosomes. Cultivated peanut is an allotetraploid (2n = 4x = 40). This test looks for changes, or abnormalities, in the chromosomes that make up your body's DNA, or genetic road map. Notice that the 23rd chromosome pair is not included in this count.
