Atomic nucleus

Cell to Cell Communication Two or multiple cells who are in a close radius have the capability to communicate with each other through the plasma membrane. Cells send signals through steps of signal transduction pathway. Cells communicate through chemical messages long distance and in a short radius. Different Types of Signaling In long distance and short distance signaling there are many different types of signaling used for communication between cells. The local communication is done through…

Eukaryotic cells are known for its organelles variety. Each organelle has its function so consequently each organelle differentiates from one another by its content. In this lab, the cells from a cauliflower were studied with the purpose to separate nuclei and mitochondria content from a solution. To achieve the results, the cauliflower solution had to go through differential centrifugation, microscopy, and succinate dehydrogenase assay. For the fist part of the lab density played a key role in…

1. What are the various phases that make up the cell cycle? Explain what happens during each phase. (4 marks) The cell cycle consists of many stages, which are separated into two phases: interphase and mitosis. During interphase, the cell grows larger and makes a copy of its own DNA. Interphase occurs for about 90% of the cell cycle and consists of the following stages: G1 phase, during which the cell grows larger and produces more of its organelles, proteins, and ribosomes. This phase ensures…

RNAs, 22 exchange RNAs, and 13 protein coding qualities (subunits of NADH, ATPase, and cytochromes). It additionally comprises of the non-coding control locale, or D-circle, which is associated with the direction of DNA replication. Not at all like atomic DNA, which is passed on from the two guardians, mitochondrial DNA is for the most part uniparentally acquired (with some outstanding exemptions). In creatures mtDNA is gone on maternally through the egg, with the exception of in bivalve…

acrosome is the part on the head of the sperm. It is located on the tip and it is made of chemicals. The function of the acrosome is to dissolve the membrane of the egg so the sperm can fertilize it. URL: https://goo.gl/m1bFIq Part: Nucleus Function: the function of the nucleus is to carry the 21 chromosomes to the egg to complete the 42 to be in the zygote URL: https://goo.gl/ED2A9S Part: Tail Sheath Function: Tail sheath acts as a cell membrane for the sperm URL: http://goo.gl/JZjVw8 Part:…

In the prokaryote cell, all the components of the cell are in the cytoplasm because they do not have a cell nucleus but in the eukaryote cell, the materials in the cell nucleus are separated from the cytoplasm. It is dominated mainly of water, but there are some enzymes like protein salts, organelles (mitochondria, Golgi apparatus and so on) and various organic molecules. The cytoplasm helps…

The Mitosis Diamond I was being chased by the biggest mob of people I 've ever seen. I was having to dodge arrows and axes it was this bad. Then I was hit!!! But first let me tell you about the beginning. It all started on a beautiful summer day at my jewelry store. Well let me go to the very beginning when I found the best jewel ever. I was hiking on a famous trail in Australia and about half way on the trail I tripped. I hit my head on a rock and I hadn’t really had a good day.…

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

FTO belongs to a member of Fe(II)- and α-ketoglutarate-dependent AlkB dioxygenase family and was originally recognized as an enzyme involved in the excision of N1- or N3-modified purine or primidine in both DNA and RNA substrates. Jia et al. for the first time demonstrated that human FTO could also demethylate m6A on nuclear RNAs in vitro, and increase and decrease in m6A was manifested in FTO-depleted and overexpressed-HeLa cell, respectively. FTO function has shown to link to the regulation of…

Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating…
