The Chipko movement was primarily for the conservation of: MCQ with Answer and Explanation

Explanation:
DNA sequencing determines the precise order of nucleotides in a DNA fragment. Sanger's dideoxy chain-termination method and next-generation sequencing are common. PCR amplifies DNA, gel electrophoresis separates by size, Southern blotting detects specific sequences. Sequencing is fundamental in genomics.

Explanation:
Mitosis is an equational division resulting in two genetically identical diploid daughter cells, not four. Meiosis is a reductional division involving two successive stages, meiosis I and meiosis II, producing four haploid cells. Crossing over, the exchange of genetic material, occurs exclusively during the pachytene stage of prophase I in meiosis, not in mitosis. Only statement 2 is correct.

Explanation:
Pepsin is the main digestive enzyme in the stomach. It is secreted by the chief cells (zymogenic cells) of the gastric glands in an inactive form called pepsinogen. Pepsinogen is activated into pepsin by the acidic environment created by hydrochloric acid (HCl) secreted by parietal cells. Pepsin then digests proteins into proteoses and peptones.
