Crossing over occurs in metaphase as soon as all the chromosomes space aligned in the center of the cell. Their close proximity enables crossing over to occur.

You are watching: In which phase will crossing-over occur


Crossing over occurs in telophase right prior to the cells split because all the DNA and also cell expansion has developed by this point.


Crossing end occurs in anaphase at every pole that the cell wherein the chromosomes room packed together.


Explanation:

Mitosis is to move cloning. This means the Mitosis ends through two the same cells; no variation. Mitosis is exactly how the human body repairs skin and other tissues. Since the tissue being repaired needs to enhance its neighboring cell, there is no need for variation i m sorry is specifically what crossing over does. It mixes-n-matches the hereditary material amongst chromosomes, which helps to provide rise come the variation we see amongst our own species and in all animals that reproduce sexually (Meiosis). 


In i m sorry stage of mitosis carry out sister chromatids line up along an imagine line the divides the cell in half?


Explanation:

Metaphase is identified by the lining increase of chromosomes along the "metaphase plate," an imagine line that divides the cabinet in half. Following metaphase and during anaphase, the sisters chromatids will certainly separate and move towards the poles that the cell.


Mitosis and also meiosis are comparable and frequently incorrectly thought of together the very same process. Which of these best explains their differences? 


Mitosis will generate 2 daughter cells with the same genetic material from the parent cell, if meiosis will certainly generate 4 daughter cells with fifty percent the genetic material indigenous the parent cell. 


Mitosis will certainly generate 4 daughter cells with fifty percent the hereditary material indigenous the parental cell, while meiosis will generate 2 daughter cells through the same genetic material from the parent cell.


Correct answer:

Mitosis will certainly generate 2 daughter cells with the same genetic material indigenous the parent cell, when meiosis will generate 4 daughter cell with half the hereditary material indigenous the parent cell. 


Explanation:

There are plenty of ways the mitosis and also meiosis differ, in this concern we are primed to look in ~ the differences in the end products of each kind of cell division.

Mitosis creates two brand-new cells that are similar to the parent cell (diploid). Meiosis creates 4 brand-new cells with half the hereditary information (haploid) in every cell, and also the cells room nonidentical to the parental cell and also to their sister cells.


Explanation:

Prophase- spindles forming, chromosomes condense, and also the atom membrane begins to rest down

Prometaphase- microtubules grow

Metaphase- chromatids are lined up in the center of the cell on the equatorial plate

Anaphase- the 2 chromatids of the chromosome are pulled apart in ~ the centromere

Telophase- new nuclear membranes kind around each collection of chromosomes, the spindles break down, and also chromosomes decondense


Which stage of mitosis exhibits the 2 chromatids that the chromosome are pulled apart at the centromere?


Explanation:

Prophase- spindles forming, chromosomes condense, and the nuclear membrane begins to break down

Prometaphase- microtubules grow

Metaphase- chromatids room lined up in the center of the cell on the equatorial plate

Anaphase- the 2 chromatids the the chromosome are pulled apart in ~ the centromere

Telophase- new nuclear membranes type around each set of chromosomes, the spindles break down, and also chromosomes decondense


Explanation:

Prophase- spindles forming, chromosomes condense, and also the atom membrane starts to rest down

Prometaphase- microtubules grow

Metaphase- chromatids are lined increase in the facility of the cell on the equatorial plate

Anaphase- the 2 chromatids that the chromosome space pulled apart in ~ the centromere

Telophase- new nuclear membranes form around each set of chromosomes, the spindles break down, and also chromosomes decondense

Explanation:

Interphase would be an initial as this is the component of the bicycle cycle the the cabinet prepares to go into Mitosis. The vital indicators of prophase space that the nuclear envelope is tho intact and the chromosomes are start to pair increase sister chromatids. The mitotic spindle is also beginning come form. Premetaphase, the following phase, is once the spindle has actually attached itself to the corresponding chromosomes and they start to migrate to the center of the cell. In Metaphase the chromosomes have actually lined up on the mitotic plate and beginning come separate. In anaphase every sister chromatid move to its respective side of the cell, together it is gift pulled over there by the mitotic spindle. The last phase the mitosis is telophase, i beg your pardon is shown by the beginning of the cell separating into two, dubbed cytokinesis.

Example question #18 : expertise Stages of Mitosis


At which step of mitosis room the chromosomes separated and also move to every side the the cell?


Possible Answers:

Metaphase


Prophase


Telophase


Premetaphase


Anaphase


Correct answer:

Anaphase


Explanation:

Anaphase is where the duplicated chromosomes split, disconnected in ~ the centromere, and also each sister chromatid is moved towards opposite sides of the cells.

Example question #19 : expertise Stages the Mitosis


Telophase is the next phase in mitosis. List two things that occur during this phase. 


Possible Answers:

The spindles start to develop and also pull each set of chromosomes to opposite sides of the cell.


Chromosomes space lined increase in the facility of the cell and also the mitotic spindle begins to pulls them in the direction of either side of the cell.


The nuclear envelope starts to malfunction and the chromosomes start to move to opposite political parties of the cell.


Chromosome sets space assembled at opposite end of the cell and also a atom envelope forms about the chromosomes. 


Chromosomes are lined up in the middle of the cell and also the nuclear envelope begins to form.


Correct answer:

Chromosome sets space assembled in ~ opposite end of the cell and a nuclear envelope forms around the chromosomes. 


Explanation:

Important indications that the cell is in telophase room that the chromosomes have actually been moved towards the opposite sides of the cell. The nuclear envelope does start to form around the brand-new respective cell nucleus of each daughter cell and the cabinet itself starts the stages of cytokinesis, or this splitting of the cell right into two daughter cells.

Example concern #20 : understanding Stages the Mitosis


What term refers to the cell separating into 2 daughter cells?


Possible Answers:

Cytokinesis


Anaphase


Telophase


Fission


Interphase


Correct answer:

Cytokinesis


Explanation:

Cytokinesis is the department of the cell into two particular daughter cells. Cytokinesis have the right to start as at an early stage as anaphase and moves v with telophase. The most essential thing in this part of the procedure is to make sure that there is one cell nucleus in each brand-new cell being formed. A protein filament ring, referred to as the contractile ring, reasons the center of the cabinet to shrink and pinch off to kind the two different daughter cells.
