5 True/False questions

  1. interphaseA the resting phase between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins

          

  2. tripleta group of three bases on DNA that codes for one amino acid.

          

  3. chromosomeA threadlike, gene-carrying structure found in the nucleus. consists of one very long DNA molecule and associated proteins.

          

  4. telophaseAfter the chromosome seperates, the cell seals off, Final Phase of Mitosis., A cleavage furrow forms during this phase, two nuclei are formed

          

  5. gap junctionCommunicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
