Indicate which of the following statements regarding haptens and carriers are true. 

#Unit 4. Cell Communication and Cell Signaling
  1. Haptens are large protein molecules such as BSA. 
  2. When a hapten-carrier complex containing multiple hapten molecules is injected into an animal, most of the induced antibodies are specific for the hapten. 
  3. Carriers are needed only if one wants to elicit a cell-mediated response. 
  4. It is necessary to immunize with a hapten-carrier complex in order to obtain antibodies directed against the hapten.

 You are a scientist who is using genomics to currently study a new bacterial species that no one has ever studied before. The following sequence is a piece of DNA within the coding region of a gene that you have recently sequenced.
 
You are using shotgun sequencing to determine the DNA sequence of the genome of this new bacterial species. For one strand of a 30-nucleotide long stretch of DNA, you get the following sequences out of your shotgun sequencing reaction. 
 
Choose correct 30-nt-long DNA sequence with the help of above-mentioned fragments
