Across
  1. 4. A specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid
  2. 6. a new organism grows by mitosis and cell division on the body of its parent
  3. 7. nitrogen-containing base found in RNA (but not in DNA) and derived from pyrimidine
  4. 9. Diffusion of water through a selectively permeable membrane
  5. 11. A type of RNA, synthesized from DNA, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein; also called messenger RNA.
  6. 12. Cytosine and Thymine
  7. 14. a change in the base sequence of a gene that results from the loss of one or more base pairs in the DNA
  8. 15. a branching diagram that depicts the evolutionary relationships among species or other taxa
  9. 20. A mutation due to an intramolecular reorganization of a gene
  10. 21. A type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses.
  11. 24. Mutation that shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide
  12. 25. DNA to RNA
  13. 26. specific codon (AUG) that signals to the ribosome that the translation commences at that point
  14. 27. gives physical support for mRNA and tRNA
Down
  1. 1. Cell division that produces reproductive cells in sexually reproducing organisms
  2. 2. DNA unzips into two parts and splits with the cell. In it's new home each side of the DNA strand attack to matching nucleotides to create 2 exact copies. It is important in puberty and other times of growth as it is the reproducing of your cells.
  3. 3. Mutation in which a single base is replaced, potentially altering the gene product.
  4. 5. helix The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape.
  5. 8. process that does not require oxygen
  6. 10. is the addition of one or more nucleotide base pairs into a DNA sequence
  7. 13. mutation A change in the sequence of the bases in a gene, which changes the structure of the polypeptide that the gene codes for.
  8. 16. (genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
  9. 17. a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix
  10. 18. Codon that signals to ribosomes to stop translation
  11. 19. group of three bases on a tRNA molecule that are complementary to an mRNA codon
  12. 22. Adenine and Guanine
  13. 23. Movement of molecules from an area of higher concentration to an area of lower concentration.
