44. Nisin is an antimicrobial peptide that is produced by bacteria in the genus Lacocous in an effort to kill competing bacteria, but is also used as a food preservative. What type of plasmid is the likely source of the gene encoding nisin?

Bacteriocins plasmids

48. DNA replication always proceeds in only one direction because the _______ of the incoming nucleotide is attached to

49. Which of the following is the best description of a gene?

a segment of DNA that is transcribed into an mRNA, a tRNA, or an rRNA

50. Many pharmaceutical drugs specifically inhibit transcription in Bacteria but not Archata or Eukarya. Why would drugs that

inhibit transcription only affect Bacteria and not Archaea even though they are both prokaryotes?

Archaca and Eukarya have very similar RNA polymerases that are different than bacterial RNA polymerases.
