Across
  1. 6. Translates the genetic information from mRNA into a specific sequence of amino acids, which are the building blocks of proteins.
  2. 8. The site of protein synthesis and is a major component of ribosomes.
  3. 10. Contains a single molecule of DNa and is a thread-like structure in the nucleus of a cell which is coiled around proteins to form a dense package of genetic material.
  4. 14. Copies the genetic information from DNA in the nucleus by creating a complementary strand of mRNA from the code on the DNA strand.
  5. 15. A permanent, random change in the DNA sequence of an organism.
  6. 16. mRNA->Amino Acid Sequence->Protein
  7. 18. A cell division that reduces the number of chromosomes in a parent cell by half to produce four daughter cells.
  8. 19. Unzips the DNA-hydrogen bonds.
  9. 20. Helps give DNA fragments together.
Down
  1. 1. The biological process of producing two identical replicas of DNA from one original molecule.
  2. 2. The term for how proteins are made within cells/organisms.
  3. 3. Consist of one or more long chains of amino acids.
  4. 4. Replicates DNA molecules to actually build a new strand of DNA.
  5. 5. DNA->mRNA
  6. 7. The building blocks of DNA.
  7. 9. Tells DNA polymerase where to start.
  8. 11. A type of nucleic acid that plays a primary role in protein synthesis, the process of making proteins.
  9. 12. When a single cell divides into two identical daughter cells.
  10. 13. The molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms.
  11. 17. A DNA segment that contains instructions for building proteins.
