Which of these results when one nitrogen base replaces another in a segment of DNA?

• an adaptation

• a feedback loop

• a mutation

• an enzyme substrate

NGSS.HS-LS3-2

The change between sequence 1 and sequence 2 above is most similar to which of the following types of mutations?

• frame shift

• point

• insertion

• deletion

Tags

NGSS.HS-LS3-2

A deletion of a DNA base from a gene affects an organism by —

• causing future gametes to have additional chromosomes

• changing the sequence of amino acids in a protein

• causing chromosome fragments to form long chains

• changing the structure of ribose sugar in nucleic acids

NGSS.HS-LS1-1

Mutations are only passed to the offspring of an organism when they happen in which of the following types of cells?

• gamete cell

• somatic cell

• blood cell

• brain cell

NGSS.HS-LS3-2

The change between the two chromosomes above is best described as which of the following types of chromosomal mutations?

• translocation

• duplication

• inversion

• deletion

A mutation is least likely to affect a cell when the mutation —

• reverses the order of bases in a DNA strand

• allows the total number of bases in a DNA sequence to remain the same

• replaces a base with its complementary base

• produces a triplet that codes for the same amino acid as the original triplet

The change between the two chromosomes to the right is best described as which of the following types of mutations?

• inversion

• deletion

• insertion

• duplication
