Nucleotide: a nucleic acid monomer, consisting of five carbon sugar covalently bonded to nitrogenous base and phosphate group. DNA “backbone” : chain nucleotide made of sugar and phosphate group that are joined together by covalent bond and are resistant to cleavage Antiparallel: the 2 strands of DNA double helix that run in opposite directions of each other Reactive chemical group at the 5’ end of DNA: phosphate group Reactive chemical group at the 3’ end of DNA : hydroxyl group The four DNA nucleobases thymine (T), adenine (A), Cytosine (C) and guanine (G) , Complementary base pairing adenine and thymine pair (A-T) and guanine and cytosine pair (G-C) Melting temperature: temperature needed to break 50% of the hydrogen bonds Chromatin:…
Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…
The role of nucleic acids are to store, express, and transmit genetic information. A nucleotide is an organic molecule having three components: one or more phosphate groups, a five carbon sugar, and a single or double ring of carbon and nitrogen atoms. Two types of nucleic acids are DNA and RNA. RNA. The structure of DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.…
Sedna- Formally known as 90377 Sedna is a large minor planet. It is in the far reaches of the solar system. It was discovered 11/14/2003. It's Aphelion (the far extreme of it's orbit) is a jaw dropping 937AU, or 87,099,591,409 miles, from the sun. It is made up of Water, Methane, and Nitrogen ices.…
Mitochondria play a very important role in the body. They create energy for the body, which is used to sustain and support growth and other functions. When the Mitochondria become diseased, the results can be disastrous. Take Mitochondrial Disease, for example. It's an inherited chronic illness that effects the mitochondria and weakens their ability to produce energy for the cell.…
3-2-1 Assignment- Genetic Inheritance 3 Main Points: 1. The cell contains three important things. Those three things are the nucleus, mitochondria, and the ribosomes. The nucleus consists of DNA and RNA molecules which contain hereditary information that has a jurisdiction of the cell’s purpose. The mitochondria contains mtDNA distinctive influence in human developmental research.…
I completed The ViualDNA Who Am I Quiz?. This quiz was based on the Big Five personality traits:openness, agreeableness, extraversion, conscientiousness, and neuroticism. The Big 5 model is a taxonomy of personality traits that helps to identify people’s descriptions, or rating, of one another (Srivastava, 2015). The model was used by early trait psychologist, such as Cattell and Fiske.…
DNA determines how our body functions and what we look like. So what is the reason that could cause our own DNA to be our downfall? Inbreeding, which is the mating of organisms that are relatives. Inbreeding or the breeding or related individuals will cause an issue known as inbreeding depression. This is when the biological fitness in a population is reduced.…
Mitochondria are filamentous organelles of all aerobic cells of higher animals and plants and also certain microorganism like protozoa. Studies show that that mitochondria are the direct descendants of a bacterial endosymbiont that became established at an early stage in a nucleus-containing host cell (Gray et al., 1999). Mitochondria are surrounded by a double-membrane system, consisting of inner and outer mitochondrial membranes separated by an intermembrane space. (Cooper, 2000). It has the outer membrane and the inner membrane.…
Mitochondria are organelles found in eukaryotes obtained through endosymbiosis with prokaryotes billions of years ago. They are organelles with their own DNA and outer and inner membrane and few organelles, because they lost many of their organelles to the Nuclear DNA of the eukaryotes which resulted them being dependent of the cell they live in This endosymbiosis is very crucial for eukaryotes survival since mitochondria produce the energy needed for the cell to survive through oxidative phosphorylation (OXPHOS) in the electron transport chain (ETC). Mitochondria is the power house where the OXPHOS takes place. It is more exposed to the toxic products of this process, like the reactive oxygen species(ROS) than any other organelles in the cell,…
These proteins determine everything from how the organism looks to how it behaves. The human genome consists of 50,000 to 100,000 genes located on 23 pairs of chromosomes. One chromosome in each pair is inherited from…
-In a SCNT, the nucleus of an egg cell is removed and it becomes an enucleated egg cell. -The nucleus is removed because the nucleus contains the majority of the genetic information (DNA). -DNA has a double helix structure and it is made from many nucleotides -Nucleotides are made from a nitrogen base (Adenine, Guanine, Cytosine, or Thymine), a phosphate group, and a deoxyribose. -The DNA is stored in the nucleus as chromatin, but during cell division the DNA stored as chromatin condense into chromosomes.…
Individuals are very unique and complicated to understand, and DNA is what makes individuals who they are. It is the code for our physical being, such as appearance, personality, and even…
Scientists classify organisms by grouping and sorting organisms together based on their physical structure, evolutionary relationships, embryonic similarities, genetic similarities, and their biochemical similarities. The most popular form of classification system used by scientists is Linnaeus’s System of Classification, by which organisms are classified and grouped into 6 different kingdoms; bacteria, archaea, protista, fungi, plant and animal. By classifying organisms it provides scientists with an easy way to study organisms efficiently, and allows for predictions and knowledged observations. Knowledge about classification allows scientists to make predictions about organisms, living and extinct. It allows for a comparison and understanding…
