Across
  1. 3. the process by which the genome's DNA is copied in cells.
  2. 5. the process in which cells make proteins.
  3. 8. the relationship between two versions of a gene.
  4. 10. a biological catalyst and is almost always a protein.
  5. 11. a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
  6. 15. having different alleles for a particular trait.
  7. 17. The process by which a single parent cell divides to make two new daughter cells.
  8. 18. The basic unit of heredity passed from parent to child.
  9. 19. a biomolecule comprised of amino acid residues joined together by peptide bonds.

  1. 1. the process by which a cell makes an RNA copy of a piece of DNA.
  2. 2. A structure found inside the nucleus of a cell.
  3. 4. the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
  4. 6. a small RNA molecule that plays a key role in protein synthesis.
  5. 7. refers to certain patterns of how traits are passed from parents to offspring.
  6. 9. a type of single-stranded RNA involved in protein synthesis.
  7. 12. One of two or more DNA sequences occurring at a particular gene locus.
  8. 13. a trait that is expressed only when genotype is homozygous
  9. 14. The presence of two identical alleles at a particular gene locus.
  10. 16. A special form of cell division in which each daughter cell receives half the amount of DNA as the parent cell.
  11. 20. ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
