  1. a a group of three bases on DNA that codes for one amino acid.
  2. b A sequence of three nucleotide bases on mRNA that refers to a specific amino acid. (if DNA triplets are AAT-CGT-TCG then related _____ on mRNA would be UUA-GCA-AGC
  3. c A substance produced by a living organism that acts as a catalyst to bring about a specific chemical reaction
  4. d A solution in which the concentration of solutes is greater than that of the cell that resides in the solution.,causes a cell to shrink because of osmosis
  5. e Anchoring junctions that prevents cells subjected to mechanical stress from being pulled apart; two adjacent cells are attached. formed from protein plaques in the the cell membranes linked by protein filaments

5 Multiple choice questions

  1. Cell's division (PMAT) of the nucleus. Final product is 2 daughter cells that are exactly like the parent cell., asexual reproduction and contains same number of chromosomes.
  2. Second Stage of Cell division: Centromeres of duplicated chromosomes are aligned at plate. chromosomes become attached to spindle fibers
  3. Division of the cytoplasm during cell division after the cell nucleus has divided.
  4. A tiny cell structure that carries out a specific function within the cell
  5. 3rd phase; the chromatids of each chromosome separate at the centromere and move in opposite poles of the spindle.

5 True/False questions

  1. concentration gradienta gradient in concentration of a solute that molecules move down and the greater the difference in concentration between the two areas, the faster diffusion occurs. It is An increase or decrease in the density of a chemical substance in an area., A difference in concentration between two areas.

          

  2. diffusionCell's division (PMAT) of the nucleus. Final product is 2 daughter cells that are exactly like the parent cell., asexual reproduction and contains same number of chromosomes.

          

  3. cell divisionProcess by which a cell divides into two new daughter cells

          

  4. endocytosisActive transport process where a cell engulfs materials with a portion of the cell's plasma membrane and releases the contents inside of the cell to form a vacuole.

          

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