The scientific name of the lion is: MCQ with Answer and Explanation

Explanation:
Monocots are less susceptible to Agrobacterium-mediated transformation using Ti plasmid. Therefore, direct gene transfer methods like particle bombardment (biolistics) are commonly used. The gene gun shoots DNA-coated gold or tungsten particles into plant cells. Ti plasmid works well for dicots. Bacteriophage and cosmids are for bacterial cloning.

Explanation:
Cacti, xerophytes, have spiny leaves to minimize surface area and transpiration, conserving water. Thus, R correctly explains A.

Explanation:
Polymerase chain reaction (PCR) amplifies a specific DNA segment exponentially using primers, DNA polymerase (Taq), and thermal cycling. Gel electrophoresis separates DNA by size, sequencing determines base order, microarray analyzes gene expression. PCR is crucial in cloning, diagnostics, and forensics.
