Which stage of the following does nuclear envelope break down?
the nuclear envelope breaks down during prophase near the same time the chromatin condenses.
Why does the nuclear envelope break down in prophase?
If the nuclear envelope didn't break down, the spindle would not attach to the kinetochore proteins on the condensed chromosomes in prometaphase because the nuclear envelope would be in the way.
What causes the base pairs in DNA to break apart?
The base pairs in DNA are broken apart during replication. Specific enzymes such as DNA polymerase break the nucleic acids apart forming two chains of DNA.
What process of two rails or sides break apart and attract new nucleotide bases to form a new and complete strand?
Replication.
DNA replication results in two identical DNA molecules. What role do DNA helicases have in DNA replication?
DNA helicases break the hydrogen bonds in the DNA molecule
What stage does the nuclear envelope break down?
During the interphase
When in the cell cycle does the nuclear membrane begin to fade?
In mitosis the nuclear envelope begins to break in prophase. In meiosis the nuclear envelope begins to break in prophase 1.
Which stage of the following does nuclear envelope break down?
the nuclear envelope breaks down during prophase near the same time the chromatin condenses.
Why does the nuclear envelope break down in prophase?
If the nuclear envelope didn't break down, the spindle would not attach to the kinetochore proteins on the condensed chromosomes in prometaphase because the nuclear envelope would be in the way.
When does the nuclear envelope break down into vesicles?
To be or not to be, that is the question.
In mitosis, when does the nuclear envelope break down?
Answerlate prophase (aka prometaphase)
Why do nitrogenous bases break apart during DNA replication?
So that the DNA can replicate/duplicate.
What disappears in the prophase of mitosis?
"...the nuclear envelope and the nucleolus break up, dispersing, and are no longer visible..." (Hole's essentials of human anatomy & physiology, 67).
Why is it important for the nuclear membrane to be broken down during mitosis?
The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA) The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be formed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.
What causes the base pairs in DNA to break apart?
The base pairs in DNA are broken apart during replication. Specific enzymes such as DNA polymerase break the nucleic acids apart forming two chains of DNA.
What process of two rails or sides break apart and attract new nucleotide bases to form a new and complete strand?
Replication.
What happens when the DNA replication complex comes across a double strand break?
It stops.
