RNA and DNA involvement in Cell Replication
Question | Answer |
---|---|
What are the 3 steps of the cell cycle during interphase. | G1 phase , S phase, G2 phase |
The DNA double helix can be released to allow replication. | True |
What is Mitosis. | The process of cell duplication in which two daughter cells receive exactly the same nuclear material as the original cell. |
The S in S phase stands for sterilization. | False |
What happens in the G1 phase. | The DNA double helix unwinds to expose the bases. |
In the G2 phase the DNA double helix unwinds with help of enzymes. | False |
The three phases of interphase allow for checkpoints to make sure things are working properly. | True |
What does the G2 interphase include. | Continued protein synthesis and cell growth in preparation for cell division. |
The G1 and G2 phases are times of growth and preparation for major changes. | True |
How is DNA double helix released to allow replication. | Enzymes imitate the process of winding DNA and releasing the two complementary strands of that DNA so that DNA polymerase enzymes can duplicate them. |
There are two steps of the cell during interphase. | False |
what does the G in G1 and G2 stand for. | Gap |
