As there were glitches with Canvas not always taking the highest of two attempts for quizzes, you will have only one attempt for this quiz. Note that only the first 10 questions are counted in your grade. The remaining 34 questions are merely practice to prepare you for exam questions. I posted additional slides from today\'s lecture that were not in the Ch 8 part 2 presentation in Canvas, these slides may be helpful for some of the questions. Which of the following NEVER results in a change in the lengths of one or more arms of a chromosome? terminal deletion reciprocal translocation paracentric inversion pericentric inversion tandem duplication.

Solution

The answer is Paracentric inversion.

Terminal deletion - alters thee length of choromosome arms.
EG: ABCD.EFGH > ABCD.EFG

Reciprocal transloaction:- alters thee length of choromosome arms.
Eg:
ABCD.EFGH > ABCD.EF890
12345.67890 >12345.67GH

Paracentric inversion: No alteration in length of choromosome arms.
Eg:
ABCD.EFGH >ABCD.GFEH   

Paracentric inversion : alters thee length of choromosome arms.
Eg:
ABCD.EFGH >ABCEF.DEH   

Tandem duplication: alters thee length of choromosome arms.
Eg:
ABCDBC.EFGH
