Chromosomal abnormalities can result from either a variation in the chromosome number or from structural changes. These events may occur spontaneously or can be induced by environmental agents such as chemicals, radiation, and t. However, mutations are most likely due to mistakes that occur when the genes are copied as the cells are dividing to produce new cells. These abnormalities may involve the autosomes, sex chromosomes, or both. The disruption of the DNA sequence or an excess or of the genes carried on the affected chromosomes results in a. Such a change may or may not alter the protein coded by a gene. Often, however, a mutation results in the disruption of gene functionality. The resulting altered or missing protein can the way a gene is meant to function and can lead to clinical disease. Only mutations occurring to the DNA in the gametes will potentially pass on to the offspring.
Mutations appear in gametes in one of two ways. A mutation may be inherited from one of an individual's parents. However, a mutation may also occur for the first time in a single, or during the process of fertilization between an egg cell and a. In this case the mutation or change is often called a de novo mutation. The parents are not affected by the condition and are not "carriers" of the mutation. The affected individual will have this mutation in all of his or her cells and may be able to pass the mutation on to any offspring.
Chromosomal aberrations can be produced by exposure to viruses, radiation, and various chemicals. Non disjunction of the twenty first chromosomal pair is Down syndrome.
a gene is passed on from generations and a chromosome is just found in certain cells
Not necessarily chromosomal mutations. Asbestos types are considered mutagens in lung cells, but any chromosomal mutation would have to be carefully engineered.
Vitamin D or cholecalciferol is the Vitamin, which is produced in the presence of ultraviolet rays in the skin.
Rubella IgG is a specific antibody which our body's defenses has produced in response to a prior exposure, in this case, the virus Rubella.
Vitamin D is produced in the skin, on exposure to UV (ultravoilet) radiation, from a modified cholesterol molecule; necessary for normal bone growth and function.
There is no actual chromosomal change, there is an extra chromosome.
yes.. it causes chromosomal aberrations to lymphocytes
Allelic diffrence in future generation can occur through chromosomal aberrations and mutaions.
Chromosomal aberrations occur when any of a number of structural changes in chromosomes. These changes result from abnormal divisions within the chromosomes, and may occur as a loss of the chromosome or the duplication of the chromosome.
Meiosis halves the chromosomal number. So haploid cells are produced

There are many synonyms for aberrations. They include anomaly, flaw, freakishness, prodigy, quirkiness, singularity, spreading, unbalanced, and unconventional.
Chromosomal Loci is a Heterozygous
learned helplessness
During the first exposure to an antigen antibodies are produced
