GE 02-59 MUTATIONS

Chromosomal mutations
1. do not change genes like that
2. do not change the structure of chromosomes
3. can be observed only by light microscope
Loss of the fragment between two breaks on the chromosome arm or...
1. ...deficiency
2. ...translocation
3. ...transformation.
Translocation means...
1. transpose of a chromosome part on another chromosome
2. loss of a chromosome part on another chromosome
3. reverse of a chromosome section
Loss of internal chromosome part is
1. deletion
2. translocation
3. reverse
Reverse of a chromosome section is
1. inversion
2. deletion
3. duplication
Duplication means
1. doubling of a chromosome part
2. reverse of a chromosome part
3. break-up of a chromosome part
chromosomal mutations arise
1. relatively often
2. very rarely
in contrast to gene mutations chromosomal mutations (aberrations) cannot be an obstacle in normal process of meiosis
1. statement is false
2. statement is true
Break-up of a chromosome into more parts
1. fragmentation
2. inversion
3. deletion
By which chromosomal mutation does the chromosomal ring arise?
1. after short deletions
2. after inversion
3. after translocation
