| Where does transcription occur? | In the nucleus. |
| Where does translation occur? | On ribosomes in the cytoplasm. |
| What is a codon? | A three-nucleotide sequence on mRNA that codes for an amino acid. |
| What is an anticodon? | A complementary sequence on tRNA that pairs with mRNA codons. |
| What molecule brings amino acids to the ribosome during translation? | tRNA. |
| What is the process of DNA copying itself called? | DNA replication. |
| What are mutations? | Changes in DNA sequence that may affect protein synthesis. |
| What is the difference between a point mutation and a frameshift mutation? | A point mutation changes a single base, while a frameshift mutation adds or removes bases, shifting the reading frame. |
| What is the role of helicase in DNA replication? | It unwinds the DNA double helix. |
