Human bone, muscle, and nerve cells all contain the same number of chromosomes with the same complement of genes. What enables these cells to perform specialized activities?

• The ability of some cells to remove unnecessary DNA sequences

• The regulation of gene expression within each cell type

• The mutation of genes within each cell type

• The use of different methods of cell division

Original: GAC-TAG-CAC

Mutated: GAC-TAA-GCAC

• A silent mutation results in the insertion of a different amino acid.

• A substitution occurs with the adenine base.

• A deletion of a cytosine base occurs.

• A base is inserted into one strand of the DNA.

The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?

• Mutations are a source of variation in the species

• Mutations are the cause of disease in the species

• Mutations are not harmful when they occur in somatic cells of the species

• Mutations are always passed on to subsequent generations of the species

Which point mutation would be most likely to have a harmful effect on the functioning of a protein?

• a base substitution

• a base deletion near the start of the coding sequence

• a base deletion near the end of the coding sequence, but not in the terminator codon

• a base insertion near the start of an intron

In the early 1980s scientists were able to produce two biomolecules by slicing a human gene into the bacterium E. coli to make recombinant human insulin and growth hormone. Which statement best explains why this experiment was successful?

• Human cells are eukaryotic, and E.coli cells are prokaryotic.

• All living organisms share the same genome.

• The genes for all organisms are composed of the same building blocks

• The human body contains many types of bacteria, including E.coli
