Across
- 3. 3 nitrogenous bases that specify the location of an amino acid when forming peptide chains
- 5. code The sequence of nucleotides in DNA or RNA that determines the specific amino acid sequence in protein synthesis
- 7. An organelle essential for mRNA translation and protein synthesis
- 8. A substance capable of increasing the activity of a catalyst to increase the rate of reaction
- 10. Part of either DNA of RNA that interrupts the sequence of genes and doesn't code for proteins
- 11. synthesis Creation of proteins using DNA, RNA and various enzymes
- 12. Instructions carried by an mRNA strand, uses these instructions to make peptide formations
- 13. In DNA replication and the strands unwind, these expose to the exposed nitrogenous bases
- 17. Composed of tightly coiled DNA, become visible in nucleus when a cell prepares to undergo mitosis
- 18. activation This process is crucial in growth and development
- 19. A molecule with genetically related amino acid attached to it
- 20. Binds to coding triplet during the translation phase of protein synthesis
Down
- 1. Opposite of Introns
- 2. strand DNA strand with the same sequence as the transcribed mRNA, gives primary sequence of a protein
- 4. Change of the nucleotide order of the DNA inside a cell
- 6. attached to its duplicate copy the chromatid
- 9. The genetic instructions on a DNA strand
- 14. Transfers the genetic information from the cell nucleus to ribosomes in the cytoplasm
- 15. Proteins that are wound around by DNA
- 16. strand DNA strand that gives the starting point for both the mRNA and DNA strand
- 17. grainy material in cell nuclei during interphase
- 21. Wound in a double helix and held together by hydrogen bonds
