|The CORRECT sequence of stages of mitosis is ________.||prophase, metaphase, anaphase, telophase|
|Which of the following is a characteristic seen in prophase I that does NOT occur in prophase II?||Crossing over occurs|
|The function of independent assortment is||create genetic diversity in the offspring|
Which of the following is a characteristic seen in prophase I that does not occur in prophase II quizlet?
Upon completion of telophase I and cytokinesis, there is(are) ______ cell(s). Which of the following is a characteristic seen in prophase I that does not occur in prophase II? Crossing over occurs. Anaphase II is essentially the same as mitotic anaphase except that in anaphase II ______ and in mitotic anaphase ______.
Which does not occur at prophase 1?
E) Homologous pairs of chromosomes align at the metaphase plate does not occur during prophase I of meiosis.
What does not occur in the prophase?
What event does not occur in prophase of mitosis? The chromosomes are replicated. … – Those attached to chromosomes elongate, while those that are unattached shorten. – Those attached to chromosomes shorten, while those that are unattached elongate.
What is the function of prophase 1?
Prophase I highlights the exchange of DNA between homologous chromosomes via a process called homologous recombination and the crossover at chiasma(ta) between non-sister chromatids. Thus, this stage is important to increase genetic variation.
What is meant by prophase?
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
What must happen before a cell can pass the G2 checkpoint?
How about for the G2 checkpoint? Before passing the G1 checkpoint, the cell must determine that the environment is favorable for cellular division. In order to pass the G2 checkpoint, all of the DNA must be duplicated and repaired before entering M phase.
What factors are evaluated before a cell is allowed to proceed through the G1 checkpoint?
Damage to DNA and other external factors are evaluated at the G1 checkpoint; if conditions are inadequate, the cell will not be allowed to continue to the S phase of interphase. The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.
