BIOTECHNOLOGY REVIEW SHEET
EXAM 2025/2026 QUESTIONS AND
ANSWERS 100% PASS
What is altering an organism's genetic code so that it produces desired protein called? -
ANS genetic engineering
Enzymes that cut DNA at specific base sequence are called? - ANS restriction enzymes
What is the name of the process that separating cut DNA fragments by size using an electric
current? - ANS gel electrophbresis
What is the name of the process that allows specific DNA fragments to be copied millions of
times by cycling of temperature? - ANS PCR
What is the name of the process that used to identify DNA when a mutation adds or deletes a
restriction site? The process is usually used to identify genes that cause genetic illness -
ANS REIPs
Process that is similar to RFLP analysis, but uses highly variable, non-coding sequences of DNA
to determine the identity of someone. The process is used in forensic applications. -
