Mutant 1 N . . . Thr-His-Ser-Val-Leu-Lys-Ala . . . C
Mutant 2 N. . . Thr-His-Ser-C
Mutant 3 N . . . Thr-Thr-Leu-Asp-C
Mutant 4 N . . . Thr-Gln-Leu-Trp-Ile-Glu-Gly . . . C

Required:
Determine the wild-type mRNA sequence.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.

Multicellular organisms use cell division, mitosis, for growth and the maintenance and repair of cells and tissues. single-celled organisms may use cell division as their method of reproduction. regardless of the reason for mitosis, the process ensures genetic continuity. what is the step in the cell cycle that ensure genetic continuity?
