Galina-37 [17]

Answer:

It seems that a reciprocal translocation is going on.

Explanation:

A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.

According to this, there are different types of translocations:

  • Intrachromosomal translocations:
  1. Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569
  2. Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789
  • Extrachromosomal translocations:
  1. Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one.
  2. Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.

Reciprocal translocations might be:

  1. Fraternal: the interchange occurs among homologous chromosomes
  2. External: the interchange occurs among non-homologous chromosomes

Reciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed.  This association is a quadrivalent structure.

During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.

How does fever indicate that your body''s immune system is doing its job?
miv72 [106K]
Fever indicates that your body's immune system is doing its job because of two key reasons. One is due to the fever creating a "speed up" in white cell production and the other is due to the fever actually destroying harmful bacteria.
