The nucleus is the largest of organelles and can be found within the nuclear envelope. The nucleus is responsible for the storage of the genetic entropy required for growth, reproduction and metabolism. Not only the cell that it controls, but also the whole organism. It controls the replication and transfer of hereditary molecules deoxyribonucleic acid and ribonucleic acid (DNA and RNA) between the parent cell and child cell. The nucleus ensures identical distribution and exact duplication of the genetic contents during cell reproduction. The nucleus sustains and controls the cell growth by arranging the synthesis of structural proteins in the cell.
The nucleus is the place for DNA transcription in which messenger RNA (mRNA) that synthesizes protein, is produced. The nucleus contains numerous types of proteins which can either directly control transcription or are indirectly involved in regulating the process. The process of energy and nutrient metabolism in the cell is regulated by the nucleus. It directs the synthesis and functioning of enzymes; a type of protein.
The selective diffusion of cell's regulatory and energy molecules through the pores in the nuclear membrane are presided over by the nucleus. Nucleus is responsible for the secretion of ribosomes. The ribosomes, in turn are responsible for synthesizing all types of proteins.

Some ribosomes are found scattered in the cytoplasm (these can be referred to as free ribosomes), while others are attached to the endoplasmic reticulum (also known as bound ribosomes). The surface of the endoplasmic reticulum when bound with ribosomes is called rough endoplasmic reticulum (RER). Both the free and bound ribosomes have similar structure and are responsible for the production of proteins. Ribosomes are responsible for assembling amino acids to form specific proteins, which in turn are essential for carrying out the cell's
parts, and each part has its own job. The nucleus of a cell is very similar
This happens because the mitochondria now has more surface area connecting it to its surroundings. The processes that the mitochondria make are to break down the high energy organic molecules into smaller more useful packages. The endoplasmic reticulum is a network of tubes and channels that transport and with the help of ribosomes produce proteins. The rough endoplasmic reticulum contains ribosomes which are not present in the smooth endoplasmic reticulum.
Organelles work together to carry out life processes and functions. Each organelle has a certain responsibility to carry out. Organelles are always working diligently to maintain a cell’s internal process and functions. Firstly, the “brain” of the cell is the nucleus. The nucleus administrates all of the cell activities. And, found within the nucleus there is genetic material called chromosomes. Secondly, the nuclear membrane surrounds the nucleus. Additionally, the mitochondria makes ATP energy from food. The lysosomes has digestive enzymes that help break food down. Furthermore, the ribosomes make protein. Then, the Golgi apparatus process and package the
Trisomy 13 or Patau Syndrome” Trisomy 13 is a genetic disorder found in babies. It is also called Patau syndrome in honor of the physician who first described it, Krause Palau. Trisomy 13 is a genetic disorder in which there is three copies of chromosomes on Chromosome 13. Patau first described the syndrome and its involvement with trisomy in 1960. It is sometimes called Bartholin-Patau syndrome, named in part for Thomas Bartholin, a French physician who described an infant with the syndrome in 1656.
Similar examples can be found in physics. Prior to the Michelson-Morley Experiment of 1887, which showed the constant speed of light, the experiments of FitzGerald and Lorentz, which explained the constant speed of light as the contraction of bodies and slowing of clocks, and the subsequent conclusion by Einstein that electromagnetic waves do not require a medium, scientists felt that light required a medium, and thus one was invented-ether (Hawking). These experiments demonstrate yet another aspect of a personal point of view in the pursuit of knowledge; the fact that despite the assumptions a personal point of view brings into a study, such as FitzGerald’s and Lorentz’s assumption that ether did, in fact, exist, knowledge can still be gained from such a study. Despite their assumption, they contributed, through their experiments, the knowledge that light does travel at a set speed. Thus, even when associated with false assumptions brought into an experiment, personal points of view are not always negative.
Mitochondria are tiny organelles found in nearly all eukaryotic cells. They are rather large organelles ranging from 0.5µm to 10µm in length and 1µm in diameter. The mitochondria are the energy factories of the cell and are located in the cytoplasm. They are the sites of cellular respiration. The mitochondria are responsible for generating ATP from such organic fuels as simple sugars and fats in the process of cellular respiration. This doubled-membrane organelle has its own DNA and can reproduce by splitting itself.
The nucleus is a organelle that controls all life activities, especially reproduction. In a basketball stadium, the head coach is like the nucleus. The head coach controls everything that happens especially what his team does. This is how the
The nucleus is the CEO of the cell. It controls all cell activity, It regulates movement, reproduction, and eating in the cell. The nucleus contains the of the cell's genetic information. This information is organized as deoxyribonucleic acid molecules, in conjunction with a spread of proteins, to create chromosomes.
Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.
In the most general terms, the nucleus is the command center of a eukaryotic cell. Although the origin of the organelle is unclear, it is believed that it is derived from a symbiosis relationship between a bacterium and an archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles and sub-regions
As previously stated the nucleus stores the cells genetic information DNA, which in mitosis passes genetic information onto daughter cells for cell division (Lawhead & Baker, 2016). The nucleus also decides which protein molecules are produced by creating ribonucleic acid (RNA) to regulate the synthesis of various enzymes cells needed for activities such as growth, metabolism and reproduction (Lippincott, 2002). Furthermore, the nucleus, by repressing certain genes, aids cell evolution by allowing genetic variation and cell
Our comparison is between the ribosome and power outlets in the house. The ribosome of a cell has four types of macromolecules. Those four types are carbohydrates, lipids, nucleic acids, and proteins. The protein is vital to cell function because proteins do pretty much everything. Some of the things they do are signaling, structure, communication, transport movement. So our analogy is good because they both are there to do whatever needs to be done. The power outlets let anything that’s plugged into them work, and the ribosome does almost everything the cell needs.
The amount of information encoded by the genes within a cell is enormous, although some will never be expressed while others occasionally during its life cycle. For example some genes that encode for ribosomal RNA are being expressed continuously because they are responsible with the formation of proteins in the cell’s cytoplasm. Specific RNA molecules and proteins are expressed in all cells at all times, their genes going under the name of housekeeping genes. They are responsible with the maintenance of the cells and can aid geneticists recognize their function (Brown, 2011).
The membrane surrounding the nucleus in eukaryotic cells, separate the nucleus from the cytoplasm. Most of the cells we used in the experiments held, were multicellular or consisting of more than one cell. A variety of cells were used in completing the experiments. We used union cells, cheek cells, potato cells, and Elodeo cells. We also used Planaria which is a unicellular organism.
