Question 4 Why is CRISPR useful for genome editing? it can't be used in humans, but it works really well in most microbes it creates really long sticky ends that improve the efficiency of creating the correct plasmid it is being used to provide immunity to viruses in humans O it can direct DNA cutting to any specific sequence

What advantageous uses have viruses been shown to have? The activities of viral genes mimic those of host genes so they are useful for studying mechanisms of DNA replication and gene expression in their much more complex hosts. O Bacteria-killing viruses may play an increasing role in the war against bacterial pathogens. O All are correct. They can be used as a means to introduce foreign genes into human cells, which may serve as a basis for treatment of human diseases by gene therapy. O Insect-killing viruses may play an increasing role in the war against insect pests.

How would you go about cloning this amplified DNA into pL4440？Using your knowledge of cloning describe 5 important aspects of the method in details

Plasmids usually contain a gene for to a make make it easy to grow only colonies of bacteria that have acquired the plasmid. antibiotic resistance O lactose intolerance color O apoptosis

Which RNA polymerase makes TRNA? RNA pol I RNA pol II RNA pol III RNA pol IV

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

Which of the following cuts DNA like molecular scissors? Clustered regularly interpaced short palindromic repeats  Cas (CRISPR associated ) proteins

Which of the following helped show that DNA is the carrier of genetic information? Check all that apply Heat-killed S bacteria can "transform" live R bacteria into a virulent strain. 20 different amino acids are found in proteins, but only 4 different nucleotides are found in DNA Bacteriophage inject DNA, not protein, into the bacteria they infect Mice injected with heat-killed R strains of bacteria die of pneumonia MacBook Pro
