Biotechnology: Principles and Processes: Class 12 Biology (UP Board) important questions and practice
Biotechnology: Principles and Processes is chapter 9 of 13 in UP Board Class 12 Biology. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Principles: genetic engineering and bioprocess engineering
- Tools: restriction enzymes (EcoRI, palindromes), cloning vectors (pBR322, Ti plasmid), competent host
- Gel electrophoresis and elution of DNA fragments
- Processes: isolation of DNA, cutting, amplification by PCR, ligation, transformation
- Selectable markers and insertional inactivation (lacZ, blue-white screening)
- Bioreactors and downstream processing
What examiners usually ask
- Draw a labelled diagram of pBR322 and explain the role of ori, rop and the selectable markers
- Describe the steps of polymerase chain reaction and mention the role of Taq polymerase
- How are competent host cells prepared and what is the role of insertional inactivation in selecting recombinants?
Exam tip
The pBR322 diagram with ori, ampR, tetR, rop and the restriction sites is asked almost every year; practise it and know that EcoRI cuts between G and A of GAATTC leaving sticky ends.
