Across
- 3. a segment of a DNA or RNA molecule which does not code for proteins and interrupts the sequence of genes.
- 7. a cell with the unique ability to develop into specialised cell types in the body.
- 8. is the reason some object or process occurred in a system that evolved through natural selection.
- 9. signals the termination of the translation process of the current protein.
- 10. a series of actions or steps taken in order to achieve a particular end.
Down
- 1. the process by which the instructions in DNA are converted into a functional product
- 2. the first of several steps of DNA based gene expression in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
- 4. a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
- 5. is the process by which DNA makes a copy of itself during cell division.
- 6. organic compounds that combine to form proteins.
- 7. a messenger RNA transcript translated by a ribosome.
- 11. a segment of a DNA or RNA molecule containing information coding for a protein or peptide sequence.
