PUBH 6011 FINAL EXAM LATEST 2022|2023|2024 REAL EXAM QUESTIONS AND ANSWERS/PUBH 6011 FINAL STUDY GUIDE 2022-2024 | A GRADED. Disease and the Environment • 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...

This set of notes contain a detailed explanations on DNA & genetics containing the following: Cell nucleus DNA - the code of life and RNA Structure & location of DNA & RNA in a cell Replication of DNA The polymerase chain reaction (PCR) Human genome Protein synthesis Genetic aberrations/mutations Application of DNA technology Meiosis Chromosomal mutations/aberrations due to abnormal meiosis Genetics & genetic engineering Punnett diagrams Genetic problems Sex determination O...

Causes of chromosomal aberrations - errors in chromosome segregation (causes whole chromosome aneuploidy) and/or DNA damage repair (causes structural variation) Anneal - the ability of two complementary nucleic acids to align in an opposing orientation to allow the nucleotide bases of one strand to form hydrogen bonds with the nucleotide bases of the complementary strand; used in microarrays to bind DNA and show fluorescence Absolute risk - A person's chances of developing a disease or dis...

PUBH 6011 Final Test with Complete Solutions Protein Synthesis - Answer-DNA to mRNA via Transcription in the nucleus of the cell. RNA to protein via translation in the ribosomes . tRNA brings amino acids to the ribosmes in the correct sequence Mutagens - Answer-pollutants in the environment that enter the body and directly change your DNA sequence Gene-gene interactions - Answer-Pollutants that affect the functioning of one gene that directly affect the functioning of another gene Po...

Genetics -study of the way such disorders occur Cytogenetics -study of chromosomes by light microscopy and the method by which chromosomal aberrations are identified -used slide to visualize the chromosomes Genes -basic unit of heredity -made up of DNA -DNA= the are interwined with one another to be able to create chromosomes -DNA= basis of heredity -RNA= synthesizes protein for cellular growth, supports DNA growth and heredity Human composed of 46 CHROMOSOMES -22 pairs of autosomes (homolous...

PUBH 6011 FINAL LATEST EXAM REAL EXAM QUESTIONS AND ANSWERS/ PUBH6011 FINAL EXAM STUDY GUIDE | A GRADE Two differences between virus and bacteria - CORRECT ANSWER- 1. Bacteria are a single cell and can exist on their own (no nuclei or substructures) 2. Viruses must invade a host cell and use its genetic DNA Role of DNA in protein synthesis ?- CORRECT ANSWER- DNA acts as a template for RNA and encodes the sequence of proteins Role of mRNA in protein synthesis - CORRECT ANSWER- mRNA i...
