Since diabetics are not able to make enough insulin, scientists use gene engineering to make it for them. they insert the gene that codes for the production of insulin in the plasmid (circular DNA of bacteria ) to create recombinent DNA, and the bacteria will asexually reproduce, making more and more of the insulin in a short amount of time! hope this helped it took me a long time to understand the whole process in this unit!
Answer:
Control of the cell cycle is necessary for different reasons. When the cell cycle are not regulated, cells could constantly undergo cell division without any form of control which will lead to cancer.
Internal regulation of the cell cycle is necessary to alert the passage of one phase to the next at a set given time. This helps in the overall metabolism of the body.
Answer:
B
Explanation:
Offspring would all have genes of TT, TT, Tt and Tt. All offspring have the dominant tall gene.
It cannot survive because an earth worm will not become 2 new worm. The head of the worm may survive and regenerate a tail. But if original tail of the worm may not survive because it will not be able to grow a new head or the rest of its vital organs and it will die. I hope this helps. :)
Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
