Mitosis

Since 1988 the plant Crupina vulgaris or the Common Crupina has been listed as a class A weed, it has invaded many parts of the Western United States, its has become a growing concern for many as it can grow quickly and is difficult to get rid of. C. vulgaris is native to Mediterranean Europe. It is a flowering plant, or angiosperm from the family Asteraceae, that can grow up to three feet tall. The stems of the plant are leafy and rigid with small spines and rounded 1/2 inch leaves near the…

The organisms used in this lab are the Ascomycota fungi Sordaria fimicola. S. fimicola is made of haploid cells in a hyphae. A diploid cell is formed when two haploid nuclei bud off of the hyphae. This diploid cell then undergoes meiosis and mitosis forming eight haploid cells called a tetrad. The cells develop within an ascospore, and a group of ascospores is an ascus. An perithecia contains the asci (Glase, 1995). S. fimicola have a unique feature in their meiotic process which easily lends…

Environmental-Dependent Sex Determination in Reptilians When we think of sex determination in organisms, we most often think of mitosis and the process of randomly receiving X and Y chromosomes from parent cells. This type of sex determination is known as genotypic sex determination (GSD), and it’s the most commonly found method of sex determination. However, this isn’t the only type of sex determination available to organisms. Some reptilians, for example, use environmental-dependent sex…

division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus. The first three steps where the cell grows, matures, and carries out its life function are collectively called interphase, followed by mitosis, and…

elongation, and termination. Eukaryotic genes are not regulated by operons, but they do have DNA binding proteins. Cell division in eukaryotes is more complex than prokaryotes. When eukaryotic cell divides it occurs in two steps: mitosis and cytokinesis. During mitosis, the nuclear membrane breaks down and reforms. The chromosomes also separate to where each daughter cell receives a diploid number of chromosomes. Cytokinesis is the division of cytoplasm that results in…

Chase Ochoa Biological Anthopology 1. Biological Anthropology, as a science, has had an enormous impact on the field of Human Anatomy. It’s given us insight into the history of human development, from where we’ve come to where we are now. Those within the science have researched mankind’s origins through the use of what was left behind: Remains of our ancestors, and the ancestors that came before we could even define ourselves as Homo Sapiens Sapiens. 2. This statement is true in numerous…

second one is called As 114d, and the third one is called Lily meiosis. Mitosis stages is animal cell. This sample is brown. It combined with two big parts of the cell. There are many small bubbles in first part. The sizes of bubbles inside the big bubble are random. They separate randomly. Some of them are stick together, and some of them are alone. The second part of the sample is white and brown. The second one is As 114d mitosis. It is the plant cell. The second one is brown. Personally, I…

Gene expression within a eukaryotic cell is directly impacted by the spatial organization of the nucleus [1]. Cellular organization is carried out at the chromosome-level [1], through means of chromosome folding, gene kissing, looping, nuclear lamina associations and protein-nucleic acid interactions within nuclear bodies. Observation of the nucleolus using Raman microspectroscopy may provide more insight into macromolecule density and distribution, as well as provide answers to the still…

Learning the science between babies is crucial for an educator to know. This concept is sort of compared to knowing your opponent before you play them in a game. This gives you different advantage points on how to handle them. Genetics, Prenatal care, and birth are the main concepts that you need to know about the history of a baby. Genetics is the disorders the child could have; usually it runs in the family. Prenatal Development is what the mother needs to know while she is pregnant; this…

Cancer is a disease of mitosis that removes the stop points on the mitosis cell and keeps building many cells. It starts with a single cell which transforms into a cancer cell. When the cell turns into a cancer cell, it forms a mass group of cancer cells called a tumor. Different cancer cells forms different cancers. The p53 gene is usually to control the cell cycle ,but it is most often mutated in over 50 percent of all cancers. The BRCA1 gene is to help suppress the tumor formation, but if it…
