PUBH 6011 FINAL LATEST EXAM REAL EXAM QUESTIONS AND ANSWERS/ PUBH6011 FINAL EXAM STUDY GUIDE | A GRADE • Understand the major functions of cells and the difference between viruses, bacteria Viruses are either naked or enveloped. Enveloped can be easily disrupted with alcohols but naked are more stable. Bacteria has different states of living. Some are free to flow while others stack up and create biofilm making them resistant • Explain protein synthesis and the role of DNA, mRNA, tRNA, ribosomes DNA is found within the chromosomes which are found in the nucleus of a cell. DNA has a nucleotide component (adenine, guanine, cytosine, thymine), phosphate group, and sugar. DNA carries the coding sequence is the template for messenger RNA (mRNA). Transfer RNA then links the amino acids which will form that specific protein by using units within ribosomes. 1) DNA is transcribed to messenger RNA via enzyme DNA Polymerase. 2) The mRNA is then spliced and the introns are then 3) Transfer RNA brings amino acids to the ribosome and creates a chain of amino acids coded bu the mRNA. Once the chain is complete it is released and folded into protein. • Explain how biological and genetic factors can influence our response to environmental hazards • Explain the role of the microbiome and its role in disease prevention • Explain how environmental factors influence genetic
