When scientist say that all living organisms share a universal genetic code it means DNA is called the universal genetic code because the structure and components of DNA are that all living organisms are related in some type of way. The universal genetic code relates to the hypotheses of life on earth by showing life originated from a single ancestor, the genetic code has more or less remained consistent. Life is a molecule that can rebuild itself, RNA-polymerase consists mostly of RNA. These fact tell that a world must have existed once, where proteins was also taken RNA molecules. The similarities of different species the scientists cut the DNA of the species into small-segments to separate the strands and mix the DNA together. When the DNA between the 2 species bonded together the match between two strands would not be perfect since there are genetic differences between the species, the more imperfect the match, the weaker the bond was. The weak bonds were broken with a little heat, while the closer required more heat to separate the strands again. The Rhesus monkey has 0 differences while Neurospora has 14 differences, I got these answers by following the chart and finding the differences and figuring out which had the same characteristics as us.

    BSC2011C Final Review Unit 1 Review Ch. 25, 22, 23, 24, 26, 19, 27 Ch. 25 1. Life is metabolism and heredity. Metabolism is the mechanism that creates order and complexity from chaos, by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication, ii. Inheritance, iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits hereditary information, but proteins do most of the work. DNA IS THE UNIVERSAL DIGITAL CODE FOR LIFE. To replicate and synthesize proteins, DNA relies on the pre-existence of protein molecules and RNA molecules. 3. RNA is the bridge between DNA and proteins, via mRNA for transcription and rRNA for translation. Thus, RNA can survive on its own while DNA relies on the existence of RNA and proteins, with them DNA is helpless. 4. The 4 points of “first life” are: 1. The Abiotic (non-living) synthesis of small organic molecules, such as amino acids and nucleotides. 2. The joining of these small molecules into macromolecules, including proteins and nucleic acids. 3. The packing of these molecules into “protobionts,” droplets with membranes hat maintained an internal chemistry different from that of their surroundings. 4. The origin of self-replicating molecules that eventually made inheritance possible. 5. The first cells to develop occurred in this order: Monomers > Polymers > Protobionts > RNA ‘world’ > DNA protobionts > first cell. 6. Fossils are the evidence of life and evolution. Organisms trapped in sediment > remain mineralized with hard and soft parts. 7. Fossils can be dated by two methods: Radiometric dating & Magnetism. In Radiometric dating, the age is based on the decay of radioactive isotopes. A radioactive “parent” isotope decays to a “daughter” isotope at a constant rate. The rate of decay is expressed by the half-life, the time requires for 50% of the parent…

    A central organizing concept in biology is that life changes and develops through evolution, and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth, both living and extinct, have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive evidence in favor of the theory of universal common descent for all bacteria, archaea, and eukaryotes (see: origin of life).[22]…

    Primate Evolution Essay

    This article relates to Big Idea 1, that the process of evolution drives the diversity and unity of life. More specifically it falls under the subunit 1B, that organisms are linked by lines of descent from common ancestry. With the discovery of a new primate species more information is found about the evolutionary history of all primates, from monkeys to humans. This ancient primate is connected to the modern day lemur, and could potentially serve as a missing link in the early branches of various lemur species. This connection is based on the idea that all organism are linked by common ancestors, and the identification of species can be determined by these genetic…

    DNA consists of two polynucleotide chains and these nucleotides consist of a deoxyribose sugar, a nitrogenous base and a phosphate group. The bases are Adenine, Cytosine, Guanine and Thymine. The sequence of these bases on DNA determines the structure of these proteins. A gene is a sequence of bases which codes for a single polypeptide. Chromosomes carry these genes and these genes come in specific forms called an allele which is how living organisms vary from each other. For example, humans are made up of an XY or XX chromosome. Females are XX and males are XY, however in some animals their sex is determined by the ZW sex-determination…

    For example, one of the most noticiable distinctions between the two is that humans are bipeda while chimpanzees walk on all fours. In addition, the chimpanzee genome was found to differ from that of humans by about 1.23%. While this figure may not seem significant to the untrained eye, it accounts for around 40 million differences in our DNA. Finally, another difference between chimps and humans is that chimpanzees are much stronger due to denser muscle fibers and phsyichemical advantages in the way their muscles contract.…
