• Positive

• Negative

• Silent

• Special

NGSS.HS-LS3-2

True or False: a genetic mutation can be present in DNA but may NOT change the amino acid sequence produced.

• TRUE

• FALSE

Tags

NGSS.HS-LS3-2

True or False: The effects of a gene mutation would only be noticeable if it eventually changed the protein being produced.

• True

• False

A permanent error in DNA or RNA is called...

• A mutation

• Transcription

• Polymerase

• Misfunction

NGSS.HS-LS1-1

NGSS.HS-LS3-2

A genetic mutation which affects part of or an entire chromosome is called...

• Gene/DNA mutation

• Chromosomal Mutation

Tags

NGSS.HS-LS3-1

A genetic mutation which affects a single nitrogen base or a single gene within DNA is called...

• Gene/DNA mutation

• Chromosomal Mutation

Tags

NGSS.HS-LS3-2

This is considered the most harmful type of gene mutation. It occurs when the codon reading frame is shifted and creates a chain reaction of errors in amino acids.

• Duplication

• Frameshift

• Insertion

• Deletion
