Question

DNA nucleotide differences between organisms:

Options

• indicate that evolution occurs

• indicate how closely related organisms are

• explain why there are phenotypic differences

• all of the above

Answer 1

all of the above

Explanation:

DNA nucleotide differences between organisms:

• Indicate that evolution occurs because changes in DNA sequences accumulate over time in populations, reflecting evolutionary processes.
• Indicate how closely related organisms are, since closely related species have fewer nucleotide differences than distantly related ones.
• Explain phenotypic differences, as nucleotide variations can affect proteins and traits, leading to observable differences among organisms.
