    DNA Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. (Miller, 139) DNA is the genetic material found in most viruses

    Eukaryotic microorganisms can be defined as organisms whose cells contain a nucleus and other organelles enclosed in membranes. It is said that all multicellular organisms are eukaryotes which mostly comprises of animals, plants, and fungi. They are known to be much larger than prokaryotes which contain no nucleus because they are multinucleated organisms. Eukaryotes were said to have developed about 1.6 – 2.1 billion years ago. But that is only an approximation. We would not be here if eukaryotic

  • Mitochondria

    Mitochondria are responsible for energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP), which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy, such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen, pyruvate or fatty

Well according to Genetics Home Research, “Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).” Mitochondria cells produce energy through a process called oxidative phosphorylation. Human DNA has about 3 billion bases in them. 99 percent of DNA is in

  • The Biological Importance of Water

    591 Words  | 2 Pages

    The Biological Importance of Water Water is a simple molecule, yet it is fundamental to life. In active living cells, two-thirds, or often more, of the area is occupied by water, and two-thirds of the globe is covered in water. Water is therefore extremely abundant, and in biological terms it has great importance both inside cells, and externally, for example as a habitat. Every chemical reaction in the human body, and any other living thing require water. We use water to dilute poisonous

    Animal Cells vs. Plant Cells Introduction Cells are the basic units of life, and they can be found everywhere that you look and go. Most cells cannot be viewed without the aid of a microscope. Plant and animal cells are very different not only in their structure shape but in their functions as well. The diagrams found in the book on pages 65-66 are described as generalized cells that are used for study purposes (Mader & Windelspecht, 2016). According to Carl Woese, a professor of microbiology
