What causes disorders such as klinefelter syndrome and turner syndrome?
Klinefelter syndrome is a chromosomal condition that only affects males and is characterized by a male having an additional X chromosome (XXY) in cells. This chromosome abnormality occurs when there is an error in cell division, resulting in an extra copy of the X chromosome.
Is Turner syndrome a chromosomal error?
Yes, it is a chromosomal error which occured most likely during meiosis. It is an error in cell division called NONDISJUNCTION. The single X chromsome is maternal, which suggests that the meiotic error tends to be paternal (3/4 of cases) -Krista D. RN
What are three types of chromosomal mutations?
Insertion, Deletion and Frameshift mutation. These are the 3 basic types of mutation, however, there are other types of mutations: substitution, translocation, duplication, inversion, transversion and transition.
Do you see a place where problems could arise during Meiosis?
During the anaphase phase of meiosis, there can be non-dysjunction. This is when the spindle fibres do not effectively pull apart the chromosomes, leading to the cells having unequal numbers of chromosomes (ie. 3 and 1 rather than 2 and 2). An example of this is Trisomy 21, which is when there is non-disjunction of the 21st chromosome in either Anaphase I or Anaphase II. This causes Down's syndrome.
How can one identify the 3' and 5' ends of DNA?
The 3' end of DNA has a free hydroxyl group on the third carbon of the sugar molecule, while the 5' end has a phosphate group attached to the fifth carbon. These structural differences can be used to identify the 3' and 5' ends of DNA molecules.
What are the 3 major chromosomal disorders?
The three major chromosomal disorders are Down syndrome, Turner syndrome, and Klinefelter syndrome. Down syndrome is characterized by an extra copy of chromosome 21, Turner syndrome involves a missing or incomplete X chromosome in females, and Klinefelter syndrome is caused by an extra X chromosome in males.

What 3 things can you determine by looking at a persons karyotype?
Their chromosomes. Karyotyping is often used to diagnose genetic disorders where there is defect at a chromosomal level, such as a transformation, or a missing/additional chromosome. In Down's Syndrome, for example, there will be an extra copy of chromosome 21 which causes the condition.
