Across
- 3. A 3-nucleotide sequence on mRNA that codes for a specific amino acid; AUG = start, UAA/UAG/UGA = stop.
- 5. The monomer of DNA and RNA; made of a phosphate group, a 5-carbon sugar, and a nitrogenous base.
- 7. The process where RNA polymerase reads a DNA template in the nucleus to produce mRNA.
- 10. Membrane-bound organelle that contains the cell's DNA and is the site of transcription.
- 11. The process where a ribosome reads mRNA codons and assembles amino acids into a polypeptide chain.
- 13. The monomer of proteins; 20 types joined by peptide bonds during translation.
- 14. The two-step process (Transcription + Translation) by which DNA instructions are used to build a protein.
- 15. Organelle made of rRNA and proteins; the site of translation in all cell types.
Down
- 1. Single-stranded RNA that carries the genetic code from the nucleus to the ribosome.
- 2. A chain of amino acids linked by peptide bonds; folds into a functional protein after translation.
- 4. The process where DNA copies itself before cell division, using each strand as a template.
- 6. The rule that A pairs with T (or U in RNA) and G pairs with C, connected by hydrogen bonds.
- 8. The fluid-filled interior of the cell outside the nucleus; the site of translation and many metabolic processes.
- 9. Double-stranded molecule that stores genetic instructions, made of nucleotides with bases A, T, G, and C arranged in a double helix.
- 12. RNA molecule that carries a specific amino acid to the ribosome; its anticodon matches the mRNA codon.
