MCB 3020 Exam Questions And Answers (Verified And Updated) Microorganisms/Microbes - answer-Small living organisms that can't be seen by the human eye - diverse in form/funtion - inhabit every EVR that supports life - many single celled, some form complex structures, some multicellular - live in microbial communities Microorganisms/Microbes - answer- oldest form of life - major fraction of earth's biomass - surround plants and animals - affect human life (infectious diseases, food a...

Define "Microbe" and discuss exceptions to the definition - Microbe: small microorganism that can cause fermentation or disease. -Found in 3 domains of life (Eukarya, Bacteria, and Archaea). Exceptions: some microorganisms and viruses does not fall within in these categories. -Viruses are acellular (not composed of cells) Compare and contrast the features of prokaryotes and eukaryotes - Prokaryotes: - Bacteria/Archaea -no membrane bound organelles -generally smaller Eukaryotes: - Pro...

RNA nucleotide base pairings - Cytosine (C) pairs to Guanine (G) Adenine (A) pairs to Uracil (U) DNA Sructure - because of this complementary base pairing, the order of the bases in one strand determines the order of the bases in the other strand Griffith's Experiment - in the 1920's, Frederick Griffith worked with two strains of Streptococcus pneumoniae bacteria. It was discovered that DNA was transmitted between the toxic and the harmless bacteria. DNA - -deoxyribonucleic acid -store...

MODULE 3 LECTURE 1: Define diffusion Which 4 factors does it depend on? What are the 2 components of random motion? - correct answer diffusion: random/non-directed motion of molecules and small particles in a liquid factors: 1) driving force (i.e. gradient, temp.) 2) mechanical resistance of the surrounding medium 3) structural properties of the molecule 4) active forces causing non-thermal fluctuations (i.e. contraction/relaxation o...

Central Dogma - Answer DNA --> mRNA ---> Proteins DNA ---> DNA = Replication DNA ---> mRNA = Transcription mRNA ---> Proteins = Translation Base + Sugar = ? - Answer Nucleoside Base + Sugar + Phosphate = ? - Answer Nucleotide Bases - Answer Adenine, guanine, cytosine, uracil (RNA specific), thymine (DNA specific) Sugars - Answer ribose (RNA), deoxyribose (DNA) Differences between DNA and RNA - Answer The DNA and RNA have 3 bases in common, A, G, and C. RNA...
