Write a paragraph on Cloning.( refer page no.108 of NCERT textbook)
Answers
Answer:
Cloning, the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination. Prokaryotic organisms (organisms lacking a cell nucleus) such as bacteria create genetically identical duplicates of themselves using binary fission or budding. In eukaryotic organisms (organisms possessing a cell nucleus) such as humans, all the cells that undergo mitosis, such as skin cells and cells lining the gastrointestinal tract, are clones; the only exceptions are gametes (eggs and sperm), which undergo meiosis and genetic recombination.
Answer:
The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. Clones are organisms that are exact genetic copies. Researchers have cloned a wide range of biological materials including genes, cells, tissues and even entire organisms.
