Nonsense

Question 7

A part in the chromosome or sequence of DNA is left out during the DNA replication

Answer 7

Chromosome Deletion

Question 8

An extra copy of segment of chromosome

Answer 8

Chromosome Duplication

Question 9

Two different chromosomes have exchange segments

Answer 9

Reciprocal Translocation

Question 10

Certain type of chromosome is attached to other

Answer 10

Robertsonian Translocation

Question 11

Chromosome segment is rearrange and is reverse. SIngle chromosome undergoes
breakage and rearrangement within itself

Answer 11

Chromosome Inversion

Question 12

● Normal chromosomes has one long arm (q) and one short arm (p) arm
● has two long arms and two short arms = extra or missing of genes

Answer 12

Isochromosomes

Question 13

● Circular structure that occurs when chromosomes break in two places and ends fuse
together
○ Caused by deletion in both arms of chromosomes and this will result in missing
DNA

Answer 13

Chromosome Rings
