Title: Translocation
Post by: Scooby on October 28, 2012, 09:41:03 pm

Does anyone know why VCAA has referred to this as translocation, rather than chromosome fusion? Or is chromosome fusion just a type of translocation?

Thanks  :)

chromosomal fusion is merely a type of translocation that involves full chromosomes. make sure that you specify that in the exam if it pops up

yeah, what curry said. do you reckon its better off stating the broader term in this case translocation than the more narrow answer, chromosom fusion.
another example would be point mutation or substitution?

on exams, i typically say:
E.g.
point mutation (specifically a substition) is whats being observed in the above DNA sequence...

Translocation (specifically chromosomal fusion between chromosomes 2 and 5) is whats being observed in the cell...

A macromutation (specifically a chromosomal segment inversion) has occurred on Jack's chromosome 6...
etc etc.

 i try doing this as much as i can, because it shows a very high understanding of the content. if you're running out of space, and can only fit in either the less specific or more specific term, always go with the more specific one. bio examiners love specifics
