3. a cell organelle that is the site of protein synthesis.
4. a nucleic acid that plays a role in protein synthesis.
5. the process of using the codons in an mRNA molecule to specify the sequence of amino acids in a protein molecule.
7. a strand of RNA that transfers amino acids to the growing end of a protein molecule during translation.
11. a subunit of a nucleic acid molecule (DNA or RNA) that consists of a sugar, phosphate, and a nitrogenous base.

1. a component of DNA that forms the “rungs” in the DNA structure.
2. the process of forming a nucleic acid by using another molecule as a template.
6. Polymerase an enzyme that enables the process of transcription by separating a strand of DNA and forming a complimentary strand of mRNA.
