  1. 3. the components of DNA and RNA that pair together to form the genetic code: adenine (A), thymine (T), cytosine (C), guanine (G), and uracil (U) in RNA.
  2. 5. the process by which different species develop and change over time through adaptations.
  3. 7. a molecule similar to DNA that plays a crucial role in protein synthesis and gene expression.
  4. 9. building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
  5. 10. the complete set of genetic material in an organism, including all of its genes.
  6. 12. the set of rules by which information in DNA is translated into proteins.
  7. 13. a well-supported explanation of an aspect of the natural world based on evidence.

  1. 1. a species from which two or more different species have evolved.
  2. 2. a diagram that shows the evolutionary relationships among different species based on shared characteristics.
  3. 3. the process by which organisms better adapted to their environment are more likely to survive and reproduce.
  4. 4. a segment of DNA that contains the instructions for producing a specific protein or trait.
  5. 6. a group of organisms that can breed together and produce fertile offspring.
  6. 8. a molecule that carries the genetic instructions for the development and function of living organisms.
  7. 11. the basic units of life that make up all living organisms, containing organelles and genetic material.
  8. 13. characteristics or features of an organism that can be inherited or influenced by the environment.
