Mitosis And Meiosis Quizzes Online & Trivia

SelenaAll are expected to have curly hair. (4.)This is part of mitosis and meiosis quiz.

This is not a good question, with two of the choices being identical, and only one of the two being correct.

Why it is 24 not 48 ... mitosis doesn't mean the double of the daughter cell!

The answer to this is A. There are some people who may find this hard to understand if they do not know what meiosis is. There are four stages available such as prophase, metaphase, anaphase, and telophase. The end result of these four stages is the production of 4 haploid cells. This means that one starting cell has the ability to form four gametes in meiosis 1. When it comes to meiosis II, the same stages will take place but this time, they will be prophase II, metaphase II, anaphase II and telophase II. The main reason why meiosis takes place is to complete the process of fertilization.

The correct answer to this question is A. Centromeres are the region of a chromosome where the microtubules of the spindle attach during cell division. Centromeres are at the end of the chromatid where two replicated sister chromatids are attached. Centromeres only appears when DNA replication occurs. The normal number of chromosomes in the cell is 10, and there are normally 5 chromosome pairs. With 20 chromatids, there would be 2 identical pairs (sister chromatids) after they have gone through replication. So there would be 10 centromeres, because you would divide the 20 chromatids in half to get the 10 centromeres.

Meiosis is a little different than mitosis. In mitosis, you get two cells at the end with the final number of chromosomes still at 40 in each cell. In meiosis, the cells divide twice: once to split up the genes into half, and then again so that each cell has only a quarter of the DNA. So, if the mother cell has 40 chromosomes, then the daughter cells will have 10 each. Each combination of genes will be different for the daughter cells, but it will still be 10 chromosomes in the end. Meiosis takes a little longer than mitosis for that reason: the mother cell has four cells to produce. Other than that, the process of meiosis does not differ from mitosis.

I take issue with your answer and find it incredibly disheartening when panicked students lose their nerves due to incorrect keys. Centrosomes move to opposite sides during PROPHASE and not PROMETAPHASE. Prometaphase is when their kinectochore microtubules attach to the microtubules of the centromeres.

Mitosis is the phase when a cell is divided into two nuclei during the cell cycle. Even though the cells are supposed to divide, there are times when they do not. During nondisjunction at least a pair of chromosomes do not divided and so there are an odd number of chromosomes. The five main stages of mitosis are prophase, prometaphase, metaphase, anaphase and telophase. Before these five stages take place, the mitosis process goes through the interphase where the cells begin and try to get ready for the next five stages. During nondisjunction in mitosis, this takes place during the G2 phase where the cell is about to divide. Then it enters into the interphase and metaphase without the cell dividing appropriately.

IncorrectWhat are the steps (in order) of mitosis?prophase metaphase anaphase telaphaseCorrect answer:prophase, metaphase, anaphase, telephaseFeedbackmy answer is correct, what is wrong with it

This needs to be changed 1 and 2 are the same answer so it is not fair because if you press 2 you are wrong

The diploid nucleus is where the core has two or a double set of chromosomes in a cell. A homologous chromosome is a pair of chromosomes that are similar. Their similarities include the size and position and a few other things. A haploid is when there is one set of chromosomes. Therefore, there may be a picture of a diploid nucleus. In this diploid nucleus, there are four chromosomes in it. Then there are also two pairs of homologous chromosomes. One of the couples is long, and the other pair is short. Also, one haploid set is symbolized as black. The different haploid set is gray. The chromosomes have not replicated yet. So, the correct chromosomal conditions for the following stage would be E, e.

There are many differences between animal and plant cells. Plant cells are usually larger. Pertaining to the shape of these cells, the plant cells are about the same in size to each other whereas the animal cells are not. The plant cells will get bigger, but the animal cells will just multiply. Cytokinesis is when the cytoplasm divides. This occurs during cell division. This happens in both animal and plant cells. During plant cells, the cell is divided by a cell plate. When the animal cell goes through cell division, it is squeezed to divide the cell. Other differences include the lysosomes in which the animal cells have enzymes and the plant cells don’t because really they don’t have as many lysosomes.
