How does CRISPR-Cas9 function using biotechnology to edit DNA?

An example of a comment on children’s art is:

The rebound hypertension that is seen when beta-adrenergic antagonists such as propranolol (Inderal) are discontinued abruptly is most probably due to which of the following 

When prescribing selective serotonin reuptake inhibitors for depression, the APRN has responsibility to monitor for adverse effects. Which of the following are among those adverse effects? Select all that apply.

Write pseudocode that creates a child process, switches the child’s standard output (1) and standard error (2), and lets the child process execute a program whose name is provided as a command line argument.  As an example, assume that helloworld binary’s main function is implemented as follows: int main(int argc, char **argv) {     write(1,”HELLO”,6);     write(2,”WORLD”,6);     return 0; } Let’s assume that the binary of the code you will implement is called changingWorlds would be called as  $ ./changingWorlds helloworld and after this the child process that will execute helloworld writes “HELLO” to file that was accessible through descriptor 2 in the parent process and writes “WORLD” to the file accessible through descriptor 1 in the parent process.

  The ribosome is important for catalyzing the formation of peptide bonds. Which of the following statements is true?  

Which of the following effects of diuretics can influence serum lithium levels?

Why is a washing step necessary during an ELISA assay?

  You have discovered a gene (Figure 7-3A) that is alternatively spliced to produce several forms of mRNA in various cell types, three of which are shown in Figure 7-3B. The lines connecting the exons that are included in the mRNA indicate the splicing. From your experiments, you know that protein translation begins in exon 1. For all forms of the mRNA, the encoded protein sequence is the same in the regions of the mRNA that correspond to exons 1 and 10. Exons 2 and 3 are alternative exons used in different mRNA, as are exons 7 and 8. Which of the following statements about exons 2 and 3 is the most accurate?   Figure 7-3  

  Which of the following statements correctly explains what it means for DNA replication to be bidirectional?
