Nucleus accumbens

mainly composed of the same things. Each organelle is significant to its cell, which are the building blocks of life. At the center of almost every cell is a dense organelle called the Nucleus. It contains the cell's genetic material and usually has a double membrane. The double membrane that protects the nucleus is similar to the thin single membrane made up of proteins and lipids. The membrane controls the passing of substances entering…

Pax6 is vital for proper eye development Eyes are essential organs for processing and interpreting sensory information in the environment, making them crucial features for many organisms to survive. The eye serves many functions, most of which are associated with a specific structure of this organ. For example, the lens, cornea, and iris are necessary for the optic capabilities of the eye. Light sensing is performed by photoreceptors located in the retinal pigmented epithelium. Transmission by…

CELLS VS. PLANT CELLS A plant cell is a eukaryotic cell, which is basically a membrane-bound nucleus. The DNA is located in a plant cell which is contained in the nucleus. Along with having a nucleus, plant cells have membrane-bound organelles. These organelles are accountable for constructing hormones and enzymes that deliver energy for a plant cell. An animal cell is as well a eukaryotic cell that has a nucleus and organelles. Animal and plant cells are very similar, but they are also very…

There are three samples of observation. The first one is called Mitotic stages, the 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…

In a cell, all of the organelles are a necessary part of the whole. The nucleus is the brains of the cell. The nucleus is also where the DNA is located. DNA are the proteins that hold the genetic code necessary for the cell to replicate. The DNA replication takes place in the ribosomes, where the proteins are translated in order to be replicated. The plasma membrane covers the entire cell and oversees the flow of chemicals that come both in and out of the cell. The plasma membrane creates a…

et Assignment 1.2 DNA or deoxyribonucleic acid is a molecule which carry genetic instruction used in the functioning ,development ,reproduction and growth of all living organism including viruses. DNA are composed of simpler monomer units called nucleotide. They are termed polynucleotide as DNA have two strands. Nucleotides is composed of four nitrogenous base, they are ADENINE(A), THYMINE (T),CYTOSINE(C), and GUANINE (G).””(DNA) DNA bases pair up with each other, A:T and C:G, to form…

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…

Structure Mitochondria are small membrane-bound organelles that are usually about 1 – 10 microns in length. They can be spherical or rod-shaped. The mitochondrion is enclosed by two membranes that separate it from the cytosol and the rest of the cell components. The membranes are lipid bilayers with proteins embedded within the layers. The inner membrane is folded to form cristae; this increases the surface area of the membrane and maximizes cellular respiration output. The region between the…
