._ are used as important vectors in genetic engineering.
Correct answer: B. Plasmids
- A. Ribosomes
- B. Plasmids
- C. Nucleoids
- D. Mesosomes
Explanation
Explanation:This option is correct because plasmids are one of the most useful and important vectors. They have natural palindromes and antibiotic resistance genes that make them useful vectors to produce transgenic bacteria.This option is not correct because Ribosomes are non membranous organelles that are sites of protein synthesis.This option is also incorrect because nucleoid is the region that has the bacteria's own DNA.This option is also incorrect because mesosomes are small invagination of bacteria's cell membrane and are site of cellular respiration, DNA replication etc.
