Document Summary
The question is: the human body has hundreds of cell types; how do different cell types differentiate? (fig. Early zebrafish development (video: timelapse in seconds that in fact takes days to complete, early development has no brush in identification. Are genes lost in the course of cell differentiation? (fig. 19. 4: the gene remains in tact, the information is all there, experiment involving three sheep: one provides the nucleus, other provides the micropipette. The haploid is replaced by the diploid (how they got the. Dna inside: cloning by nuclear transfer argues against gene loss resulting in an identical to sheep number 1. Died relatively young due to issues but she was overall healthy and was able to provide offspring. A lot of the (cid:498)extra stuff(cid:499) in the genomes of more complex organisms has to do with the (cid:498)regulation(cid:499) aka not a loss.
