How do cells created through meiosis differ from somatic cells? Why does meiosis occur? Why must DNA be packed into chromosomes before mitosis can occur? A) During mitosis, the chromosomes are replicated, is the cell still diploid? B) After meiosis, the gametes only have 1/4 number of...
Mitosis and meiosis bothinvolve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development....
On the other hand, meiosis is the type of cell division that is used for producing sex cells (gametes).Answer and Explanation: Onion root tips are the apex region of the root of onions, so it is the part of the root that grows in the ground, increasing the stability of the...Become...
Duringmitosis the sister chromatids separate and go to opposite ends of the dividing cell. Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs...
Pollen grains are created through the process of meiosis, during which cells divide and grow in number. The grains of pollen are often located in pollen sacs on the ends of the stamen (the male parts of the flower), which typically surround the carpel (the female parts of the flower). ...
In nature, living thingsevolvethrough changes in theirDNA. In an animal like a chicken, DNA from a male sperm cell and a female ovum (egg) meet and combine to form a zygote, the firstcellof a new baby chicken. This first cell divides innumerable times to form all of the cells of the...
The anther wall formation of fertile stamens is of the basic type, and the simultaneous meiosis form tetrahedral tetrads, while mature pollens are 2-celled and tricolpate. Sporogenous tissue of staminodes fails to develop further at an earlier stage, without the formation of secondary sporogenous...
It may be preceded by a premeiotic endomitosis (Dawley and Bogart, 1989) or include an endomeiosis without separation of the two cells and followed by a gathering of the two chromosomal sets (Simon et al., 2003). This gathering may also concern two cells resulting from distinct meioses....
” The strategy was to design an algorithm that would input a seed question, generate a set of constraints that characterized the relationship between conceptsAandB, then output all pairs of concepts that met the constraints, thus generating more questions of the form “What is the difference ...
What types of cells have chromosomes? What do the X and Y chromosomes stand for? What is a homologous chromosome pair? What do chromosomes do only once in mitosis and meiosis? In humans, what is chromosome pair 23 called? In humans, what are chromosome pairs 1 through 22 called? What mo...
