A piece of a chromosome breaks off and re-attaches to a nonhomologous chromosome

• inversion

• deletion

• duplication

• translocation

NGSS.HS-LS3-2

An extra copy of a region in the DNA is produced, which can be in the normal part of the chromosome or in a different part.

• deletion

• inversion

• duplication

• translocation

A portion of the chromosome is flipped )reversed) and gets inserted back into the chromosome

• inversion

• deletion

• duplication

• translocation

The diagram represents which type of chromosomal mutation?

• deletion

• duplication

• inversion

• translocation

The statements below describe the type of mutation illustrated above. Select TWO correct answers that describe the action and/or effects of this type of mutation.

• A chromosome breaks and the fragmented pieces re-attach to different chromosomes

• this type of mutation is due to incorrect copying of the second chromosome of a matched pair

• since the same genes are present, although rearranged, this type of mutation is usually non-harmful

• mutations of this type usually result in cancerous cell division

• the effects depend on which chromosomes break, and at which points. Normal gene function can be disrupted.

A​ (a)   is a specific sequence of DNA that contains the instructions for ma​king a protein. ​ (b)   occurs when the DNA sequence is copied into an mRNA molecule. mRNA then moves into the cytoplasm and looks for a ​ (c)   . ​ (d)   is where the information in the mRNA is used to assemble an amino acid into a polypeptide chain.

Reorder the followingA child is born with developmental delays and learning disabilities. After genetic testing, it is determined that the child has chromosomes in which a few have longer or shorter sections than normal. It is learned that the DNA in the gametes underwent a rearrangement/reattaching that led to these developmental issues. Click the type of genetic mutation in the diagram below that this situation describes.

• translocation

• 
• inversion

• 
• deletion

• 
• duplication

DNA sequence after mutation:
TACGAATGGAAT

• His is replaced by Ala

• Iso is replaced by Leu

• Try is replaced by Thr

• Alg is replaced by Met
