QUESTION 20 In order to produce a(n) 0.5 dilution, in a total volume of 5 mL, how many mL of sample would be required? QUESTION 21 Group II viruses violate the Central Dogma. In the blank below, enter either True or False, followed by the number that best corresponds to your reasoning, e.g. False1 or True2 1. Group Il Viruses still use a DNA genome as a template for anti-sense DNA, which is then used as a template for RNA, which is then translated to proteins. This is still DNA->RNA->Protein. 2. Group lIl Viruses use an RNA genome as a template for for proteins. 3. Group ll Viruses use a DNA genome as a template for DNA, which is then transcribed to mRNA. The Central Dogma is DNA -> RNA-> Protein. Group II viruses use a DNA-> DNA->RNA->Protein pathway. 4. Group II Viruses use an RNA genome to synthesize DNA, which is then used to synthesize mRNA, which is then used to synthesize proteins. This is still DNA-> RNA-> Protein QUESTION 22 Which groups of viruses require an RNA-dependent RNA polymerase? Retrovirus )sSRNA (+)SsDNA dsRNA (+IssRNA dsDNA QUESTION 23 Match the protein that helps initiate transcription with the domain of life it is found in. Bacteria A Sigma Factor (o factor) Archaea Transcription Factor B (TFB) Eukaryotes , Transcription Factor II B (TFIIB)Explanation / Answer
1) In order to produce 0.5% dilution in a total volume of 5ml, 0.025 ml of sample should be added. 5*0.5%=0.025.
