How does DNA analysis help scientists better understand evolution?
A. It shows us what codons an organism has.
B. It helps chart changes in amino acid sequences over time.
C. It spells out the amino acids that make up an organism.
D. It shows us an organism’s genome sequence
B. It helps chart changes in amino acid sequences over time.
DNA analysis allows scientists to compare the genetic sequences of different organisms and track changes in those sequences over time. By studying these changes, scientists can better understand the evolutionary relationships between different species and how they have evolved over time. This information can provide valuable insights into the processes of evolution and how different species have adapted to their environments.
