| Question | Answer |
|---|---|
| Process in which mRNA ( messenger) is synthesized from the template DNA | transcription |
| Process in which mRNA attaches to the ribosome and a protein is assembled | translation |
| A self-replicating material present in nearly all living organisms as the carrier of genetic information in chromosomes | DNA |
| A nucleic acid that is single-stranded and plays a major role in carrying out (completing) protein synthesis ( protein making) | RNA |
| Twisted-ladder shape of DNA, formed by two nucleotide strands twisted around each other | Double Helix |
| Permanent change in a cell's DNA, ranging from changes in a single base pair to deletions of large sections of chromosomes | Mutation |
| Complex process where the original(parent) strands of DNA in a double helix are separated and each one is copied to produce a new identical daughter strand. | replication |
| Sequence of three DNA or three RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis | Codon |

| Substance(s) formed by a chemical reaction; located on the right side of the arrow in a chemical equation | Product |
| The green pigment found in the chloroplasts of higher plants, which is primarily involved in absorbing light energy for photosynthesis | Chlorophyll |
| Cell organelle that helps synthesize(make) proteins | Ribosome |
