One Health- Exam One 1. A) Why is the One Health paradigm important? The One Health initiative is a change in basic assumptions that focuses on surveillance of the environment‚ animals‚ and humans to predict occurrence of an outbreak before it happens. This is important in improving the health of communities because preventative measures will be used and it also makes people aware of what could happen if preventative measures were not taken. Scientists and doctors worldwide collaborate to develop

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

Chapter 18 The Genetics of Viruses and Bacteria Lecture Outline Overview: Microbial Model Systems Viruses and bacteria are the simplest biological systems—microbial models in which scientists find life’s fundamental molecular mechanisms in their most basic‚ accessible forms. Molecular biology was born in the laboratories of microbiologists studying viruses and bacteria. Microbes such as E. coli and its viruses are called model systems because of their use in studies that reveal broad biological

Viroids are plant pathogens that consist of a short stretch (a few hundred nucleobases) of highly complementary‚ circular‚ single-stranded RNA without the protein coat that is typical for viruses.[1] The smallest discovered is a 220 nucleobase scRNA (small cytoplasmic RNA) associated with the rice yellow mottle sobemovirus (RYMV).[2] In comparison‚ the genome of the smallest known viruses capable of causing an infection by themselves are around 2kilobases in size. The human pathogen hepatitis D is

Section 10-2 VOCABULARY REVIEW 1. mRNA carries genetic information from the DNA in the nucleus to the cytosol of a eukaryotic cell. 2. tRNA is a chain of RNA nucleotides that are folded into a hairpin shape and can bind to a specific amino acid. 3. Transcription is the process by which genetic information is copied from DNA to RNA. 4. A promoter is a region of DNA that marks the beginning of the DNA chain that is to be transcribed.

RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

Uncontrolled transposition is deleterious to the cell and thus‚ the frequency of transposition is generally kept to a minimum by various regulatory mechanisms. Describe the FOUR ways that transposition is controlled. Transposition is the movement of a particular fragment of DNA from one part of a genome to another. A transposon is a segment of DNA which is capable of moving from a specific location on a DNA molecule to another location on the same or different molecule. For this reason‚ it is
