A mutation in biology refers to changes in the nucleotide sequence of an organism's genome. These alterations can either be harmful, leading to conditions like cancer, or beneficial, such as providing antibiotic resistance. Mutations can occur in somatic cells or gametes, affecting both the individu

Cell division involves two main processes: mitosis and meiosis. Mitosis is responsible for the division of somatic cells, producing identical daughter cells. It consists of prophase, metaphase, anaphase, and telophase, followed by cytokinesis. In contrast, meiosis is crucial for the formation of gam

Watermelons undergo the processes of mitosis and meiosis to grow and reproduce. During mitosis, watermelons develop through interphase, prophase, metaphase, anaphase, and telophase. In meiosis, seeded watermelons produce gametes through prophase I, metaphase I, anaphase I, and telophase I. Both proc
