What chromosome is Isobrachial?
In metacentric chromosome centromere is present in the middle so, these chromosomes are isobrachial. In anaphase the chromosome appear V shaped.
What is the function of the kinetochore?
In eukaryotes, the kinetochore is a proteinaceous multi-subunit assembly whose main function is to generate load-bearing attachments of sister chromatids (the replicated chromosomes held together by the protein complex cohesin) to spindle microtubules during cell division (mitosis or meiosis) (Figure 1A).
Can a human have 24 chromosomes?
In 1923 he published his results. Sperm contained 24 chromosomes, so if there were an equal number coming from the egg then humans must have 48 chromosomes in total, 24 pairs. Case closed.

A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Can you live without a chromosome?
Yes, but there are usually associated health problems. The only case where a missing chromosome is tolerated is when an X or a Y chromosome is missing. This condition, called Turner syndrome or XO, affects about 1 out of every 2,500 females.
