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.

  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

  Sometimes, chemical damage to DNA can occur just before DNA replication begins, not giving the repair system enough time to correct the error before the DNA is duplicated. This gives rise to mutation. If the cytosine in the sequence TCAT is deaminated and not repaired, which of the following is the point mutation you would observe after this segment has undergone two rounds of DNA replication?
