Across
- 3. The bases A/T and C/G are always 1:1
- 4. Directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins
- 9. copying DNA onto RNA by initiation, elongation and termination
- 10. A permanent change in the nucleotide sequence of a gene
- 11. numerical results/ objective
- 14. Parts of cells that control spindles
- 16. Characteristics visible to the eye
- 22. Making pre-mRNA into mature mRNA
- 24. Filaments involved in moving and segregating chromatids in cell division
- 25. Formed in the nucleus by transcription and carries a copy of DNA nucleotide to ribosome to create protein
- 26. non-coding regions of DNA
Down
- 1. makes the ribosomes
