Answer: Option D
Solution (By JKExamLibrary)
The common garden pea is scientifically named Pisum sativum. It belongs to the family Fabaceae. Mendel chose this plant for his genetic experiments because it has easily distinguishable contrasting traits, a short generation time, and is primarily self-pollinating. Cicer arietinum is chickpea, and Phaseolus vulgaris is the common bean.
Explanation:
Agarose gel electrophoresis separates DNA fragments by size under an electric field; smaller fragments migrate faster. PCR amplifies DNA, sequencing determines base order, cloning produces copies.
Explanation:
The corpus callosum is a thick band of nerve fibers that connects the left and right cerebral hemispheres, allowing interhemispheric communication. The thalamus is a sensory relay station, hypothalamus regulates homeostasis, pons is part of the brainstem. Severing the corpus callosum results in split-brain syndrome.
Explanation:
