1. Nucleus- present only in eukaryotic cells, this structure stores most of the genetic information of the cell. The nucleus directs the production of proteins through the synthesis of mRNA. 2.
Unlike archaea and bacteria eukarya is the type of cell with a nucleus.
Kylinn Walston RADT 3143 Chapter 1: Cellular Biology 1-1. Explain how the structure of the plasma membrane influences the movement of oxygen, carbon dioxide, and sodium ions. a. The plasma membrane is extremely important because of its multi-functionality to each cell, it is what keeps the cell complete. The membrane structure is determined by the lipid bilayer, and proteins determine the membrane functions. The membrane has a lipid bilayer containing hydrophobic and hydrophilic regions. This bilayer blocks hydrophilic substances from passing while still allowing water diffusion.
a.) The nucleus of a eukaryotic cell is surrounded by two phospholipid bilayer membranes, with nuclear pores connecting them and regulating the movement of materials between the nucleus and the cytosol (1). The nucleus of a eukaryotic cell is the largest organelle, and within in it is the DNA. The DNA within each cell is identical within every cell in an organism, with only small differences due to mutations. The DNA within a nucleus is consists of two chains of combinations of Adenine, Thymine, Guanine, and Cytosine, with each chain held together by a Phosphate-deoxyribose backbone (1).
Cell division of both prokaryotes and eukaryotes, the cell is divided into two daughter cells. Only after the dividing cell replicates its DNA and then allocates the copies towards the opposite ends of the cell, will the cell be able to successfully split into daughter cells. The DNA molecules are tightly packaged into structures called chromosomes. Eukaryotic chromosomes consist of a long singular DNA molecule associated with many proteins. The associated proteins are able to maintain the structure of the chromosome and assist control of the gene activity.
1.) Structure of nucleus and function For being so small the nucleus packs a ton of information and subspaces into it. Our DNA has the blueprints for every protein in our body, all packaged into a neat double helix. The processes to transform DNA into proteins are known as transcription and translation, and happen in different compartments within the cell.
Prokaryotes are much simpler in their organization than are eukaryotes. There are a great many more organelles in eukaryotes, also more chromosomes. The usual method of prokaryote cell division is termed binary fission (The method by which bacteria reproduce. The circular DNA molecule is replicated; then the cell splits into two identical cells, each containing an exact copy of the original cell's DNA.). The
Moreover, eukaryotic cells are organized with many membrane bound organelles. This compartmentalizations, which occurs in eukaryotic cells, this allows the cell to perform incompatible chemical reactions concurrently. It’s function also increases the surface area of the cell membrane, this is a necessity when cells take in nutrient and excrete their waste products. All of the cell’s organelles functions must work together coordinately to make sure all the needs of the cell are met. For example, energy production, cell reproduction, synthesis of proteins, photosynthesis and membrane construction.
All eukaryotic cells are membrane-bound, containing cell organelles which are there for specific functions. The main two types of eukaryotic cell are animal and plant cells, which have some similar but some different cell organelles as they are needed for a range of different functions. They both share the organelles, the nucleus, plasma membrane, nucleolus, endoplasmic reticulum (rough and smooth), golgi body, lysosomes, mitochondria, ribosomes and cytoplasm. However plant eukaryotic cells contain chloroplasts and have a cell wall which animal cells don’t.
Both prokaryote and eukaryote cells have a cell membrane. The cell membrane has a vital role in the functioning of a cell as it not only keeps all cellular components of the cell within the cell, but it controls what enters and exits the cell. The membrane covers the surface of all living cells which contains most organelles within the cells, enabling the cells to change shape. While the membrane partakes a number of different functions so the cell can survive, it is most responsible for the action of diffusion and osmosis within the cell.
The first and most obvious similarity that the two types of cells, plants and animals, share is the nucleus. The nucleus is where the cell’s DNA is stored. This organelle is covered by a second membrane and contains its own nucleoplasm which serves a similar purpose to the cell’s cytoplasm but is inside a nuclear membrane to keep the chromatin from spilling into the cell itself. The nucleus acts as the control center for the cell, maintaining homeostasis, and choosing when to divide. Contained on the DNA is the genetic code for the ribosomes needed for protein synthesis which is crucial to the cell’s life.
The DNA of eukaryotic cells are more complex and extensive. The organelle of eukaryotic allow them to
The more that is known about DNA and RNA the better we understand on how it reacts, replicates, and produces proteins in varying environments. With the information that have today we have a rather sufficient grasp on how DNA replicates itself, how DNA produces RNA and vice versa, how RNA replicates itself, and how RNA makes the final product of proteins. Here, we will specifically look at how DNA transcribes into RNA within bacteria and eukaryotes. The main differences between the two transcription process is eukaryotes have a nucleus where the RNA is transcribed and processed while bacteria do not have a nucleus so the RNA is transcribed in the cytoplasm and the RNA is not processed after transcription. They are similar in the fact
The nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long. This mean that 6 feet of DNA fits inside the nucleus, which occupies about 10% of a total cell (https://en.wikipedia.org/wiki/Cell_nucleus), of a microscopic cell. For this to happen eight separate histone protein subunits attach to the DNA molecule to
By taking Cell Biology, it not only will provide me with a base level understanding of the foundation of life, but it will also teach me how to further analyze that information and project it into more complex concepts in my world. My major career goal is to be a physician, but before I can accomplish that I have to go to med school, and, without the core fundamentals of life that is taught in Cell Biology, I would have a hard time fully grasping the “why” and “how” of further and more complex processes and concepts that I will have to learn. When it comes to Science courses, my strengths include being detailed oriented, being well organized with assignments and notes, having a photographic memory that easily recalls information once studied, and putting in a great amount of effort because I have a true love for science. However, I am not perfect and I have weaknesses well, which include not always asking for help when I need it, getting hard on myself for not doing well/understanding a certain concept, and waiting for the last couple of days before a test to study. When preparing/studying for an exam, I have a routine that I typically follow.
