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

You are watching: In which phase does crossing over occur


Crossing over occurs in telophase right prior to the cell split due to the fact that all the DNA and also cell growth has arisen by this point.


Crossing over occurs in anaphase at each pole that the cell wherein the chromosomes are packed together.


Explanation:

Mitosis is cellular cloning. This means that Mitosis ends through two identical cells; no variation. Mitosis is just how the human body repairs skin and also other tissues. Due to the fact that the tissue being repaired demands to match its neighboring cell, over there is no need for variation which is exactly what crossing over does. It mixes-n-matches the genetic material among chromosomes, which help to provide rise come the variation us see amongst our own species and in all animals that give birth sexually (Meiosis). 


In i beg your pardon stage of mitosis carry out sister chromatids line up along an imagine line that divides the cabinet in half?


Explanation:

Metaphase is identified by the lining increase of chromosomes along the "metaphase plate," an imaginary line the divides the cabinet in half. Adhering to metaphase and also during anaphase, the sister chromatids will certainly separate and also move towards the poles the the cell.


Mitosis and meiosis are similar and regularly incorrectly thought of together the very same process. Which of these finest explains their differences? 


Mitosis will generate two daughter cells through the same hereditary material indigenous the parent cell, while meiosis will certainly generate 4 daughter cell with half the hereditary material native the parental cell. 


Mitosis will certainly generate 4 daughter cell with half 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 two daughter cells v the same genetic material from the parent cell, if meiosis will certainly generate 4 daughter cell with half the hereditary material from the parental cell. 


Explanation:

There are numerous ways that mitosis and meiosis differ, in this question we are primed to look in ~ the differences in the end commodities of each type of cell division.

Mitosis creates two brand-new cells the are the same to the parental cell (diploid). Meiosis creates 4 new cells with fifty percent the genetic information (haploid) in each cell, and the cells room nonidentical to the parental cell and also to your sister cells.


Explanation:

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

Prometaphase- microtubules grow

Metaphase- chromatids space lined up in the center of the cabinet on the equatorial plate

Anaphase- the two chromatids of the chromosome room pulled apart at the centromere

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


Which phase of mitosis exhibits the 2 chromatids the the chromosome are pulled apart in ~ the centromere?


Explanation:

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

Prometaphase- microtubules grow

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

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

Telophase- new atom membranes kind around each set of chromosomes, the spindles rest down, and also chromosomes decondense


Explanation:

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

Prometaphase- microtubules grow

Metaphase- chromatids room lined increase in the center of the cabinet on the equatorial plate

Anaphase- the 2 chromatids of the chromosome room pulled apart at the centromere

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

Explanation:

Interphase would be very first as this is the part of the bike cycle that the cell prepares to get in Mitosis. The vital indicators that prophase space that the nuclear envelope is still intact and the chromosomes are beginning to pair up sister chromatids. The mitotic spindle is also beginning come form. Premetaphase, the following phase, is as soon as the spindle has attached chin to the corresponding chromosomes and they start to move to the center of the cell. In Metaphase the chromosomes have lined up on the mitotic plate and also beginning come separate. In anaphase every sister chromatid move to its respective side that the cell, as it is gift pulled there by the mitotic spindle. The last phase of mitosis is telophase, which is indicated by the beginning of the cell separating into two, called cytokinesis.

Example inquiry #18 : understanding Stages that 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 whereby the duplicated chromosomes split, disconnected in ~ the centromere, and each sister chromatid is relocated towards opposite sides of the cells.

Example concern #19 : knowledge Stages that Mitosis


Telophase is the following phase in mitosis. Perform two points that occur throughout this phase. 


Possible Answers:

The spindles begin to develop and also pull each set of chromosomes come opposite political parties of the cell.


Chromosomes are lined increase in the facility of the cell and the mitotic spindle starts to traction them in the direction of either next of the cell.


The atom envelope begins to break down and the chromosomes start to move to opposite political parties of the cell.


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


Chromosomes are lined increase in the middle of the cell and also the nuclear envelope starts to form.


Correct answer:

Chromosome sets room assembled in ~ opposite ends of the cell and a nuclear envelope forms approximately the chromosomes. 


Explanation:

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

Example inquiry #20 : expertise Stages of Mitosis


What term refers to the cell splitting 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 deserve to start as early on as anaphase and also moves with with telophase. The most vital thing in this part of the procedure is come make certain that there is one nucleus in each new cell being formed. A protein filament ring, referred to as the contractile ring, reasons the center of the cabinet to shrink and also pinch turn off to form the two separate daughter cells.
