Which of the following is the chief DNA polymerases responsible for the majority of the DNA replication in the prokaryotes? DNA Polymerase I DNA Polymerase II DNA Polymerase III All of the above

Will an unknown/experimental virus DNA sample is applied to a Vicrochip DNA microrray stick to one spot or more spots? From the following options which is the best choice It will stick to several spots since there're many pieces of DNA that can come from a single virus sample It will stick to one spot since only one piece of DNA on the chip will be able to hybridize with the sample DNA It will stick to several spots since there're always hybridization erros and the sample DNA probably contains DNA from several other viruses It will stick to one spot since the DNA is from one single virus None of the above

What is the purpose of reverse transcriptase in retroviruses? It translates viral RNA into proteins. It converts host cell RNA into viral DNA. It uses viral RNA as a template for DNA synthesis. It uses viral RNA as a template for making more viral RNA strands.
