5 True/False questions
interphase → A the resting phase between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
triplet → a group of three bases on DNA that codes for one amino acid.
chromosome → A threadlike, gene-carrying structure found in the nucleus. consists of one very long DNA molecule and associated proteins.
telophase → After the chromosome seperates, the cell seals off, Final Phase of Mitosis., A cleavage furrow forms during this phase, two nuclei are formed
gap junction → Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
