As biotechnology has improved, scientists are able to look more closely at dna, the molecules that hold genetic instructions for development, reproduction, and functioning. the ability to study dna closely allows scientists to find evidence of genetic mutation and better understand the effects of these changes. think about how genetic mutations can be harmful, beneficial, or cause no change at all.
answer choices:
-a mutation in the hemoglobin gene can result in sickle cell anemia.
-a mutation that could cause a genetic disorder gets repaired by enzymes before an altered protein is produced.
-over time, a population of green lizards that live in a desert with white sand become much lighter in color.
-a mutation of a protein results result in protection against a destructive bacteria.
-a mutation occurs in a non-coding portion of dna and does not change the amino acid sequence of a protein.
-an extra copy of a human chromosome results in a child born with down's syndrome.
