Sometimes mutations in DNA can cause control of the cell cycle to fail. What might happen if such a mutation occurred in a person's DNA?
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
When DNA replication occurs before meiosis the original DNA strand cag ccg tag is copied into complementary strand gtc aca ggc atc what type of mutation has occurred?
inversion
How did sutton's two graduate school papers help to expand our understanding of genetics?
He observed that chromosomes occurred in distinct pairs, and that each chromosome goes to its own cell. Sutton published a paper on this and made ground breaking discoveries in genetics.
What major event happens just before prophase 1 of meiosis but does not occur before prophase 2?
DNA has already duplicated back in the S phase. centrosome has doubled. in other words DNA replication has occurred!
Why is the replication process is a source of few mutations?
Some mutations are due to errors in DNA replication. During the replication process, DNA polymerase chooses complementary nucleotide triphosphates from the cellular pool. Then the nucleotide triphosphate is converted to a nucleotide monophosphate and aligned with the template nucleotide. A mismatched nucleotide slips through this selection process only onece per 100,000 base pairs at most. The mismatched nucleotide causes a pause in replication, during which it is excised from the daughter strand and replaced with the correct nucleotide. After this so-called proofreading has occurred, the error rate is only one per 1 billion base pairs.
How many chromosomes in an infant?
46 unless a mutation has occurred
What would happen if cytokineses occurred without mitosis?
The cell ensures that mitosis and cytokinesis occurred without any mistakes.
But the end of prophase each of the following has occurred except?
lining up of chromosomes in the cell
What would you see if point mutation occurred during DNA replication?
A change to the newly synthesized DNA strand, but not the template.

The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
What would happen to the number of chromosomes in a cell if mitosis occurred but cytokinesis did not take place?
The chromosomes would still duplicate, but the parent cell wouldn't split into the two daughter cells.
What would happen if cytokinesis occurred before telophase was completed?
If cytokinesis took place before mitosis then the cell would not be able to divide evenly. This would cause one cell to have part of the organelles and the other cell to have to rest of the organelles.
What would happen if cytokinesis occurred without mitosis explain?
The chromosomes would not have replicated, so the resulting daughter cells will not have the correct ploidy.
When DNA replication occurs before meiosis the original DNA strand GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG. What type of mutation has occurred?
insertion
When DNA replication occurs before meiosis the original DNA strand CAG CCG TAG is copied into complementary strand GTC ACA GGC ATC. What type of mutation has occurred?
insertion
Is the order of base pairsfrom top to bottomdifferent or the same for each new DNA molecules?
Assuming that no errors occurred during DNA replication, both copies of the new DNA molecules should be identical.

inversion
