Across
  1. 2. after proteins are built these molecules transfer each amino acid to the ribosome.
  2. 5. Pumps out oxygen rich blood.
  3. 6. proteins are built on ribosomes, which are made of two subunits made up of these molecules.
  4. 10. The two DNA strands are held together by weak hydrogen bonds between these base pairs
  5. 14. A nucleic acid that consists of a long chain of nucleotides
  6. 16. Bubble like structures that provide an enormous amount of surface area.
  7. 17. Father of Evolution
  8. 18. RNA holds the code for making proteins which are long chains of amino acids called ____
  9. 20. genes carry instructions from DNA for assembling amino acids into proteins, it carries these copies of instructions to the cell
  10. 22. a single imaginary plane divides the body into left and right sides.

  10. 15. Reads along each naked single strand adding the complementary nucleotide.
  11. 19. The process in which animals remove ammonia waste.
  12. 20. Structures that concentrate waste and add them to digestive wastes.
  13. 21. body cavity only partially lined with mesoderm.
