It is defined as the process by which a cell will segregate the cellular constituents that include cytoplasm and genetic components and thus, produces new cells. Meiosis, binary fission, and mitosis are three kinds of cell division.Answer and Explanation: The cell organelles involved in cell divis...
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have onlyone set of chromosomes: they are haploid. They have undergone a process of cell division calledmeiosis. During meiosis, crossing over occurs. This make...
What is one way that bacterial and archaeal cells differ from each other? What are some examples of specialized cells? What are Purkinje cells? What are epidermal dendritic cells? What kind of cells are lymphocytes? What are killer T-cells made of? Where do primordial germ cells originate? W...
2a) present in salivary gland cells of third instar larvae (Additional file 1: Video S1). These can be used to visualize events taking place at particular loci using a combination of FISH/RISH with confocal IF (e.g. [25, 26]). The fly system is also connected with polyploid nuclei of...
To answer the question, we need to break down the process of meiotic division in the secondary oocyte and identify what induces its completion, as well as the resultant cells formed. Here’s a step-by-step solution:Step 1: Understanding
When a protein is covalently and irreversibly bound to DNA (i.e., a DNA–protein cross-link [DPC]), it may obstruct any DNA-based transaction, such as transcription and replication. DPC formation is very common in cells, as it can arise from endogenous factors, such as aldehyde produced ...
[25, 26]). The fly system is also connected with polyploid nuclei of nurse cells in egg chambers reaching up to 1024 N in the nuclei of cells next to the oocyte (Fig. 2d). The chromatin organization of such nuclei may serve as an excellent control for chromatin organization in the ...
An example of such a reduction is seen in a study of human cells in which centromere 21 spontaneously lost a specific portion of the centromeric repeat array at a measurable frequency [25]. Although rice centromeres 4 and 8 do not contain massive arrays of CentO, other rice centromeres do...
the lumen from the sertoli cells. Following this, they are passed into the epididymis where they experience the other events pertaining to maturation to turn into fully mature spermatozoa. The process of Spermatidogenesis produces spermatids and cells participate in spermiogenesis to produce spermatozoa...
Meiosis is sometimes called reductive cell division. It's a process of cutting a cell in half, twice, in order to halve the number of chromosomes. These halved-chromosomed cells (called haploids) are the sperm and egg, which will join together to make a brand new organism....
