Mitosis and meiosis are two kinds of cell divisions. Mitosis occurs in almost all somatic/body cells and results in two daughter cells that are identical. Meiosis results in 4 haploid cells which are gametes.Answer and Explanation: Mitosis and meiosis have the same stages: prophase, metaphase, ...
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stages. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding...
1.The process of becoming mature. 2.Biology a.The processes by which gametes are formed, including the reduction of chromosomes in a germ cell from the diploid number to the haploid number by meiosis. b.The final differentiation processes in biological systems, such as the final ripening of ...
A centrosomal protein, pericentrin, was found tightly localized adjacent to nuclear lamina in UR, lacking any MT nucleation activity. In concordance with the competency to resume meiosis, an increase in the amount and nucleation capacity of pericentrin is noted. In FR, cytoplasmic MT almost ...
Ova in the primordial follicle are arrested prophase I of meiosis I. The primordial follicles maintain a dormant state until activated by signals from the pituitary gland to start the process of follicle development. Primary Follicle Stage Upon the beginning of the menstrual cycle, the hypothalamus ...

Shortening of the male-sterile maize stalks was studied to determine when the morphological differences between the three versions become evident during plant development. Since shortening usually occurred in the internodes above the ear, meiosis was selected as the reference point. Plants were examined...
the culture medium was replaced with 10% FBS lacking antibiotics. Six hours post-transfection, the medium was refreshed with 10% FBS. After 48 h, firefly and sea kidney luciferase activity were measured to assess the targeting effects ofssc-miR-133a-3ponKCNA1using the Duo-LiteTM Luciferase ...
What is Routine activity theory? Describe the activity of chromosomes in each stage of meiosis 1 and meiosis 2. How would you describe the universe? Explain the processes or stages of wetland eutrification. Which major event during meiosis is most likely to produce deviations from Mendel's laws...
