which resembles mitosis but is considerably simpler owing to the less complex structure of bacterial DNA and cells. All eukaryotes, on the other hand – plants, animals and fungi – undergo both mitosis and meiosis.
One major difference between mitosis and meiosis that can contribute significantly to genetic diversity in offspring is referred to as "crossing over" or "chromosomal crossover." Crossing over occurs only in meiosis. Homologous chromosomes can physically "swap" chromosomal segments, thereby ensuring that...
What happens to chromosomes during meiosis? In a healthy biological male, when do mitosis and meiosis occur? What type of tissue is produced by each and what causes each process to start? Which event takes place during meiosis ii? What event occurs in both anaphase of mitosis and anaphase II...
What type of cell division generates most of the cells in the human body? a) mitosis b) meiosis c) cytokinesis d) dyad formation What does the biological term cytokinesis refer to? What type of cell division occurs in somatic cells of multi-celled organisms (non-sex cells)...
As its name suggests, DNA replication (i.e., synthesis) occurs during the S phase. During mitosis, a cell divides and splits its entire contents (including its chromosomes) between two daughter cells.As you can imagine, the cell cycle is a tightly regulated process. There are checkpoints ...
the coolest phase of meiosis. The 46 chromosomes in your body’s diploid cells are organized into 23 homologous pairs. One chromosome in each of these pairs is from your mom, and the other one is from your dad. Prophase in mitosis and prophase I of meiosis both start out with double thi...
However, in meiosis, the cycle occurs twice (meiosis I and meiosis II) before the four haploid daughter cells are produced. Another difference between the stages of mitosis and meiosis is that in meiosis, homologous chromosomes pair up during metaphase instead of chromatids. In a homologous pair...
Unlike mitosis where only one division occurs, cells undergoing meiosis experience two cell divisions. The first division is similar to mitosis and results in two daughter cells with the same number of chromosomes as the mother cell. These two daughter cells then experience a second division to ma...
division. Any failure ofhomologous chromosomesor chromatids to separate correctly is known as nondisjunction. Nondisjunction occurs during anaphase of mitosis or either stage of meiosis. Half of the resulting daughter cells from nondisjunction have too many chromosomes and the other half have none at ...
What event occurs in both anaphase of mitosis and anaphase II of meiosis II? At the end of telophase, what must occur? What happens when mitosis of somatic cells goes unchecked? Distinguish what happens in metaphase and anaphase of meiosis 1 and the same phases of meiosis 2. What major eve...
