The spindle is the structure that pulls the chromatids to opposite ends of the cell during the cell division processes of mitosis and meiosis. Once separated, each chromatid becomes a chromosome. Thus, when the cell divides, both daughter cells have complete sets of chromosomes....
What is the main difference between sperms and eggs of humans ? Write the importance of this difference. View Solution What are the main differences between electromotive force of cells and cell potential? List the main differences between 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...
This process is present only in the bodies of multicellular organisms and serves several functions, such as repair, growth regulation, and formation of gametic cells. There are two mechanisms for this physiological process; ...
Meiosis vs. mitosis. Image fromA&P 6. Prophase I is, in my opinion, 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. Prop...

One such case is DNA repair at the natural ends of linear chromosomes, known as telomeres, which can lead to chromosome-end fusions. Here, we review data obtained over the past decade and discuss the mechanisms that protect mammalian chromosome ends from the DNA damage response. We also ...
Diagram for Meiosis. Meiosis is a type of cell division in which a single cell undergoes division twice to produce four haploid daughter cells. The cells produced are known as the sex cells or gametes (sperms and egg). The diagram of meiosis is beneficial for class 10 and 12 and is freq...
Osmosis is of two types: Endosmosis– When a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid or undergoes deplasmolysis. This is known as endosmosis. Exosmosis– When a substance is placed in a hypertonic solution, the solve...
