Across
- 4. an enzyme that separates double stranded nucleic acids into single strands
- 6. the process by which a cell makes an RNA copy of a piece of DNA
- 7. a segment of DNA that contains the instructions for building a specific protein or RNA molecule
- 8. the building block of nucleic acids like DNA and RNA, composed of a sugar group, a phosphate group, and a nitrogen nouse base
- 9. a type of RNA molecule that carries genetic instructions from DNA to the ribosome

Down
- 1. the process where a double stranded DNA molecule is copied to produce two identical DNA molecules
- 2. the biological process by which proteins are created in cells
- 3. a thread like structure within the nucleus of a cell, composed of DNA and proteins that carry genetic information in the form of genes
- 5. a molecule that is present in the majority of living organisms and viruses
- 10. a change in the DNA sequence of an organism, which can result from errors in DNA replication, exposure to mutagens, or viral infection
- 13. a RNA molecule that acts as an adapter, carrying amino acids to the ribosome during protein synthesis
- 14. an enzyme that catalyzes the joining of molecules by forming a new chemical bond
- 15. a type of cell division where a single cell divides into two identical daughter cells, each containing the same number and type of chromosomes as the parent cell
- 16. an enzyme that synthesizes short RNA sequences, acting as a starting point for DNA polymerase to begin adding DNA nucleotdies
- 17. the molecule that carries genetic information for the development and function of an organism
- 19. an enzyme that creates DNA/RNA polymers
