2 Genetics questions

Postby DeltaHQ » Thu Apr 20, 2017 8:36 pm

1) A child born to a perfectly healthy family was diagnosed with a rare disease. After abnormal behavior in the child, the family decided to get his DNA checked via 23andme company and also consult an oncology doctor. The child was diagnosed with chronic myelogenous leukemia. When the sequence of his DNA was retrieved, the doctors told the parents of the child that the chromosomal sequence of the child was different than his parents. In fact, especially one of the chromosomes (chromosome 8) looked extensively long (like chromosome 1). How could this child acquire this kind of extension in the chromosome?

2)What are the two terminators in prokaryotes and how do they work to stop transcription?
