D Extension at 94°C, Denaturation at 72°C, Annealing at 50-60°C

NEET Biology

Bt cotton is resistant to bollworms because it expresses a toxin derived from:

A Pseudomonas

B Bacillus thuringiensis

C Sacharomyces cerevisiae

D Aspergillus niger

NEET Biology

Which of the following is the correct statement about "DNA fingerprinting" as developed by Alec Jeffreys?

A DNA fingerprinting uses repetitive DNA sequences (VNTRs) that vary between individuals to create a unique genetic profile for identification

B DNA fingerprinting sequences the entire genome of an individual to identify them

C DNA fingerprinting compares only the mitochondrial DNA between individuals

D DNA fingerprinting uses protein patterns from blood samples for identification

NEET Biology

Which of the following is the correct example of a biotechnological application of recombinant DNA technology?

A Production of insulin using E. coli

B Cross-breeding two varieties of rice

C Selection of disease-resistant plants

D Mass selection of high-yielding crops

NEET Biology

Vector in recombinant DNA technology refers to:

A A plasmid or virus used to transfer foreign DNA into a host cell

B An enzyme that cuts DNA at specific sequences

C A method to amplify DNA sequences

D A type of gel used to separate DNA fragments

NEET Biology

Which of the following is the correct statement about "DNA profiling" in forensic science and its applications?

A DNA profiling uses STR (Short Tandem Repeat) markers analyzed by PCR to create a unique genetic fingerprint; it is used for paternity testing, forensic identification, and disaster victim identification

B DNA profiling sequences the entire human genome to identify individuals, which takes only a few hours

C DNA profiling compares blood types (A, B, AB, O) to identify individuals with high accuracy

D DNA profiling can only be done on blood samples and cannot be performed on other biological materials

NEET Biology

In biotechnology, which vector is commonly used for cloning genes in plants?

A pBR322

B pUC19

C Agrobacterium tumefaciens Ti plasmid

D pGEM-T
