What is Cloning: Definition and 53 Discussions

Cloning is the process of producing individuals with identical or virtually identical DNA, either naturally or artificially. In nature, many organisms produce clones through asexual reproduction. Cloning in biotechnology refers to the process of creating clones of organisms or copies of cells or DNA fragments (molecular cloning).

    Writing: Input Wanted Clone Ship vs. Generation Ship

    We've just had an interesting thread about generation ships, but I don't think that that is the most reasonable way to colonize another planet. Fatal problems: - Crew may become chaotic and self destructive. - Crew may become so adapted to space as to be unwilling to return to a planet. -...

    Questions Regarding Methods of Gene Cloning

    I have been told that the traditional restriction digestion cloning method, where you use restriction enzyme to produce sticky ends in the gene of interest and the plasmid vector, is vulnerable to contamination. The lecturer proceeds to conclude that Gibson Assembly Cloning is therefore a...

    How can I clone a USB drive to a VFD file for use in Windows?

    I have a USB drive that I want to clone to a disk file to be mounted under Windows (so that I can send the file to people instead of sending them the pendrive itself). Doing so under linux is trivial with dd/mount, technically I see no reason why it couldn't be done under Windows as well, but I...

    Will Pet Cloning become the Test Bed for Vertebrate Germline Transformation

    The Ethics and Progress of Cloning: Exploring the Current Status

    No-cloning and stimulated emission
