Ribosome

transduction → Process where a signal from outside of the cell changes something within the cell Ribosome depurination → In N-glycosidic link leading to the loss of a purine base while leaving the DNA backbone unharmed…

Movement of cells are important since some cells depends on movement to carry out its major function. For example, sperm cells need to move from one place to another place to carry out reproduction. Movement of cells are supported by cytoskeleton system of the cells. The cyctoskeleton system are composed of microtubules, microfilaments and intermediate filaments. However, for unicellular organisms such as Paramecium, the movement of cells are regulated through cilia or flagella. Cilia can be…

DNA and RNA are nucleic acids that takes part in protein synthesis. The nucleic acid has molecules that are big. Nucleotides has phosphorus, atoms, hydrogen and oxygen that creates them. Each nucleotide has ribosome or deoxyribose. DNA is the genetic material of a cell that has a repeating chain of five-carbon sugars connected together. It has four organic bases which are called nucleotides. There’s also deoxyribose which is a sugar that is in a double helix shape. DNA molecules…

Restrictions on Antibiotics The CDC estimates that more than 200,000 people are hospitalized each year with the flu or with flu-related complications. Most people will believe that antibiotics are the resolution to all of their illnesses when in actuality, they are wrong. Antibiotics are not the resolve to every illness, in most cases antibiotics can work negatively. Antibiotic overuse is a serious matter that must be addressed by more people. The use of antibiotics should be restricted to…

messenger rna the structure of messenger rna : Messenger RNA functions as the template for protein synthesis it carries genetic information from DNA to a ribosome and helps to assemble amino acids in their correct order. Each amino acid in a protein is specified by a set of three nucleotides in the mRNA, called a codon. Both prokaryotic and eukaryotic mRNAs contain three primaryregions .The 5 untranslated region is a sequence of nucleotides that is at the 5 end of the mRNA and does not code for…

golgi apparatus to package and deliver materials within the cell. Also, they both have a nucleus, the control center of a cell. Within the nucleus there is a nucleolus that creates ribosomes, chromatin that holds information, and a nuclear envelope that controls the materials that pass in and out of the nucleus. The ribosome create proteins for the cell. Surrounding the nucleus are the smooth and rough endoplasmic reticulum. These create the materials that the golgi apparatus ships. Likewise,…

physiology of Human Body Systems Task 1: ORGANELLE DIAGRAM FORM FUNCTION Nucleolus • The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi apparatus A group of fluid-filled flattened membrane…

go to ribosomes in the cytoplasm. In the process of translation, mRNA, tRNA, and the ribosome all work together to create the protein. The ribosomes hold the mRNA and allows the tRNA to come in with the amino acids (building blocks of protein) to match up with the corresponding mRNA codons (coding blocks) which finalizes the process of protein synthesis. (Campbell, 85-86)…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

about its structure. “Pro” means before and “kary” means nucleus. The inside of Prokaryote cell is a single-celled organism and basically an open unit with no compartments. There is no membrane bound organelles. However, small structures called Ribosomes are scattered throughout Cytoplasm. The cell’s DNA is located in the region of Cytoplasm called the Nucleoid region. The Nucleoid region is not the same thing as Nucleus because it’s not enclosed by a membrane. Prokaryote…
