when a segment of one chromosome has been swapped with a segment from the other.

A reciprocal chromosomal translocation that results in the philadelphia chromosome is a translocation between

• chromosome 22

• chromosome 9

• chromosome 17

• chromosome 21

Select all that is true: During interphase...

• the cell expresses many of its genes

• duplicates its chromosomes

• duplicated chromosomes condense

• nuclear envelope breaks down

Once chromosomes are duplicated, the cell can enter this phase

• G1 phase
• G phase

• M phase
• S phase
