Gregor Mendel proposed the laws of inheritance, later termed Mendelism, foundational to genetics.
DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.
Phylum Arthropoda, the largest animal phylum, shows jointed feet and chitinous exoskeleton.
Ernst Haeckel’s theory states ontogeny (embryonic development) recapitulates phylogeny (evolutionary history).
Pheromones are chemical signals released by animals to communicate, attract mates, or warn others.
DNA fingerprinting (DNA profiling) identifies individuals by analysing repetitive DNA sequence variations.
India belongs to the Oriental (Indomalayan) zoogeographic realm, east of Wallace’s line.
Thomas Hunt Morgan discovered crossing over using Drosophila melanogaster in 1910.
Osmoregulation maintains water and solute balance across semipermeable membranes in body fluids.
It chronologically orders Earth’s history into eons, eras, periods, and epochs based on fossil records.
